When Should a Respiratory Therapist Notify the Physician?

Respiratory therapists routinely make clinical decisions that extend beyond performing ordered treatments. They must assess patients, recognize deterioration, identify complications, question unsafe orders, and communicate significant findings to the appropriate provider.

Knowing when to notify the physician is therefore an important part of respiratory care.

In some situations, notification is the next appropriate step after assessment. In others, the therapist must first stop treatment, stabilize the patient, or activate an emergency response. Understanding this sequence helps protect patients and supports appropriate clinical decision-making.

Why Physician Notification Matters in Respiratory Care

Respiratory therapists often spend significant time at the bedside and may be among the first clinicians to recognize changes in a patient’s cardiopulmonary status. A patient may suddenly develop hypoxemia, tachycardia, bronchospasm, altered mental status, hypotension, an arrhythmia, or another complication during therapy.

These findings may indicate that the patient’s condition has changed enough to require a new medical decision. The physician may need to modify a medication dose, discontinue a treatment, order additional testing, change ventilator settings, evaluate a new complication, or adjust the overall plan of care.

Physician notification is especially important when:

• A critical laboratory or diagnostic result is identified
• The patient’s condition significantly deteriorates
• A serious adverse reaction occurs during therapy
• A treatment appears unsafe or inappropriate
• A physician order is questionable or incomplete
• The patient refuses prescribed therapy
• A new cardiac arrhythmia develops
• Oxygen or ventilatory requirements increase substantially
• An unexpected airway problem occurs
• A respiratory therapy procedure produces a significant complication
• Assessment findings suggest a new medical problem

Note: The therapist must also determine whether physician notification should occur immediately or after an urgent intervention has already been initiated.

Stabilize the Patient Before Making a Routine Call

One of the most important principles in respiratory care is that physician notification should never delay necessary emergency treatment.

If a patient is rapidly deteriorating, the therapist should not leave the bedside simply to make a routine phone call. Immediate threats to airway, breathing, oxygenation, ventilation, or circulation should be addressed first.

For example, if a patient becomes severely hypoxemic during therapy, the therapist may need to stop the procedure, administer oxygen, restore ventilatory support, reposition the patient, or activate the emergency response system.

The general sequence is:

1. Recognize the problem.
2. Stop or pause the causative therapy if necessary.
3. Remain with the patient.
4. Stabilize airway, breathing, and circulation.
5. Obtain assistance when needed.
6. Notify the physician or responsible provider.
7. Reassess the patient.
8. Document the event.

Note: This sequence is particularly important on respiratory therapy examinations. “Notify the physician” may be an appropriate answer, but it is not always the first action when the patient is experiencing an immediate life-threatening problem.

Critical Laboratory and Diagnostic Findings

Critical laboratory results represent one of the clearest situations in which the physician should be notified promptly.

A critical value is substantially outside the expected range and may represent a potentially dangerous physiologic abnormality. Respiratory therapists commonly encounter critical results involving arterial blood gases, oxygenation, ventilation, acid-base balance, electrolytes, and other measurements relevant to cardiopulmonary function.

Obtaining the result is only part of the therapist’s responsibility. A critical value must be communicated to someone who has the authority to evaluate the patient’s condition and modify the treatment plan.

Read-Back and Verification

When receiving a critical laboratory value, the therapist should verify the information carefully. A read-back process may be used to ensure that the result was heard correctly.

The therapist should then communicate the critical value to the physician, physician assistant, nurse practitioner, or other responsible provider according to institutional policy.

Documentation should include the relevant result, the time it was received, the person who was notified, and any intervention performed. Errors in communication can be especially dangerous when dealing with critical PaO₂, PaCO₂, pH, electrolyte values, or other findings that may require immediate intervention.

Questionable or Potentially Unsafe Physician Orders

Respiratory therapists are responsible for recognizing orders that appear incomplete, inappropriate, or potentially unsafe. An order should not be followed blindly simply because it was written by a physician.

For example, a medication order may contain an unusually large dosage, an inappropriate route, incomplete instructions, or another apparent error. The therapist should not knowingly administer an unsafe treatment.

At the same time, the therapist should not independently rewrite the order or simply substitute what seems like the correct dose. Instead, the therapist should contact the prescribing provider for clarification.

This principle can be summarized as follows:

• Do not carry out an order that appears unsafe.
• Do not independently alter the order without authorization.
• Contact the prescribing provider for clarification.
• Document the clarification according to institutional policy.

Note: This situation differs from an emergency caused by patient deterioration. When the problem involves an unsafe order before treatment begins, the appropriate action is generally to withhold the questionable intervention and clarify the order before proceeding.

Significant Changes in the Patient’s Condition

Respiratory care requires continuous comparison between the patient’s current condition and previous findings.

The therapist should monitor for changes in:

• Respiratory rate
• Heart rate
• Blood pressure
• Oxygen saturation
• Breath sounds
• Work of breathing
• Mental status
• Cough
• Secretions
• Skin color
• Chest pain
• Dyspnea
• Ventilator parameters
• Oxygen requirements

A significant change may indicate deterioration even before the patient reaches a critical state.

For example, a patient who previously required minimal supplemental oxygen but suddenly needs a substantially higher FiO₂ may be experiencing worsening gas exchange. Increasing oxygen requirements should not be viewed merely as an equipment adjustment. They may reflect progression of pneumonia, pulmonary edema, atelectasis, acute respiratory failure, or another underlying problem.

The physician should therefore be informed when respiratory support requirements increase significantly or when clinical findings suggest that the existing plan of care is no longer adequate.

Adverse Reactions During Respiratory Therapy

Any respiratory procedure can produce complications. The therapist should understand the expected risks of each treatment and monitor for adverse responses before, during, and after therapy.

Potential warning signs include:

• New or worsening dyspnea
• Cyanosis
• Pallor
• Diaphoresis
• Dizziness
• Chest discomfort
• Hemoptysis
• Severe coughing
• Nausea or vomiting
• Wheezing
• Stridor
• Decreased breath sounds
• Significant oxygen desaturation
• Altered consciousness
• Tachycardia
• Bradycardia
• Cardiac arrhythmias
• Marked blood pressure changes

Note: Significant adverse findings generally require reassessment and may require discontinuation of therapy. A useful concept is to stop the causative treatment, remain with the patient, stabilize the patient, and then notify the appropriate provider.

Changes in Heart Rate During Bronchodilator Therapy

Beta-adrenergic bronchodilators may produce cardiovascular side effects, particularly increases in heart rate.

The patient’s pulse should be assessed before and during treatment. A heart rate increase of approximately 20% from baseline is often considered clinically significant in respiratory therapy testing situations.

A mild increase in pulse does not always require stopping treatment. The therapist must determine whether the change is clinically meaningful.

If the patient’s heart rate rises substantially, the therapist should reassess the patient and consider pausing treatment. If the heart rate returns toward baseline and the therapy is resumed, the patient should continue to be monitored closely.

If significant tachycardia recurs, the therapy should generally be stopped and the physician notified. Persistent tachycardia, palpitations, or cardiac arrhythmias may lead the physician to reduce the medication dosage, change the medication, or discontinue the treatment.

Note: The key principle is that a significant adverse cardiovascular response should not be ignored simply because tachycardia is a known side effect of beta agonists.

Cardiac Arrhythmias During Respiratory Treatment

A new cardiac dysrhythmia developing during respiratory therapy requires careful attention. Beta agonists, hypoxemia, acidosis, electrolyte abnormalities, myocardial ischemia, stress, and direct stimulation of the myocardium can all contribute to rhythm disturbances.

Premature Ventricular Contractions

Premature ventricular contractions may develop because of hypoxemia, myocardial irritation, medication effects, electrolyte disturbances, or other physiologic stressors.

If PVCs appear during a respiratory procedure, the therapist should evaluate the patient’s condition, stop the procedure when appropriate, provide supplemental oxygen if needed, and notify the physician.

Atrial Fibrillation and Atrial Flutter

If atrial fibrillation develops during respiratory therapy, the treatment should be stopped and the patient should be assessed and stabilized. Atrial fibrillation typically involves an irregular rhythm, variable R-R intervals, absent identifiable P waves, and a fibrillatory baseline.

If the rhythm develops during treatment, physician notification is appropriate because medication effects or physiologic stress may be contributing.

If atrial fibrillation or flutter was already present before treatment, the therapist should assess the patient’s baseline rhythm and heart rate and follow the established treatment plan. Consultation may still be appropriate if the patient’s status has changed.

Allergic and Serious Medication Reactions

Respiratory medications can occasionally produce allergic or severe adverse reactions.

The therapist should monitor the patient for findings such as:

• Difficulty breathing
• Hives
• Swelling
• Redness
• Stridor
• Wheezing
• Sudden hypotension
• Rapid deterioration

If a medication appears to be causing a serious reaction, the medication should be discontinued. The therapist should remain with the patient, assess airway and breathing, administer appropriate respiratory support, and obtain emergency assistance when indicated.

The physician and nurse should be notified as part of the response. A major allergic reaction may require activation of the hospital’s emergency response system rather than relying solely on routine physician notification.

Bronchospasm During Aerosol Therapy

Aerosol therapy may occasionally trigger bronchospasm rather than improve airflow. The patient may develop increased wheezing, chest tightness, coughing, dyspnea, decreased airflow, or worsening oxygenation.

When significant bronchospasm develops during therapy, the treatment should be stopped. Oxygen should be administered or increased if needed, and the patient should be monitored closely.

The physician should be contacted regarding further treatment. Depending on the situation, the provider may order another bronchodilator, change the medication, or modify the treatment plan. The therapist should not continue an obviously harmful therapy simply because the treatment was originally prescribed.

Minor Reactions Versus Serious Reactions

Not every adverse response requires immediate physician notification. Some reactions are minor, reversible, and easily corrected.

For example, a patient performing incentive spirometry may become dizzy because of hyperventilation. In that situation, the therapist can stop the procedure temporarily, allow the patient to rest, and resume therapy more slowly after symptoms resolve.

By contrast, serious findings such as persistent bronchospasm, marked hypoxemia, severe fatigue, arrhythmias, hypotension, hemoptysis, or altered consciousness require more aggressive action. The therapist should distinguish between a temporary problem that can be corrected at the bedside and a significant complication requiring a change in the medical plan of care.

Patient Refusal of Respiratory Treatment

A competent patient has the right to refuse treatment. The therapist should never attempt to force a competent patient to accept respiratory therapy simply because a physician ordered it. When a patient refuses, the therapist should first determine why.

Possible reasons include:

• Anxiety
• Fear
• Fatigue
• Discomfort
• Misunderstanding
• Previous negative experiences
• Language barriers
• Hearing impairment
• Concern about side effects

The therapist should explain the purpose of the therapy, expected benefits, and potential consequences of refusing it. Clear communication may resolve the problem.

If the patient continues to refuse after appropriate explanation, the therapist should respect the decision. The nurse or physician should be notified, and the refusal should be documented.

Documentation should generally include what treatment was refused, what education was provided, the patient’s response, and who was informed.

Mechanical Ventilation and Hemodynamic Deterioration

Mechanical ventilation can affect both the respiratory and cardiovascular systems. Positive-pressure ventilation increases intrathoracic pressure and can reduce venous return to the heart. This effect becomes particularly important when airway pressures or PEEP are increased.

A mechanically ventilated patient who develops decreasing blood pressure with increasing heart rate may be experiencing reduced cardiac output related to excessive intrathoracic pressure. The therapist should assess the patient and ventilator, evaluate recent changes, and determine whether immediate intervention is needed.

Significant hemodynamic deterioration associated with a ventilator change should be communicated to the physician so that the respiratory and cardiovascular effects of the intervention can be evaluated. Blood gases or appropriate noninvasive monitoring may also be necessary after major ventilator adjustments that could substantially alter PaO₂ or PaCO₂.

Deterioration During Ventilator Weaning

Spontaneous breathing trials increase the patient’s respiratory workload and may also increase cardiovascular stress. The therapist should closely monitor patients during weaning.

Signs of intolerance may include:

• Sustained tachypnea
• Oxygen desaturation
• Tachycardia
• Bradycardia
• Significant blood pressure changes
• Agitation
• Anxiety
• Diaphoresis
• Altered consciousness
• Increasing respiratory distress

Note: When sustained signs of intolerance occur, the patient should generally be returned to appropriate ventilatory support. The therapist should then communicate the results to the physician or responsible provider.

Cardiac Ischemia During Weaning

Cardiac abnormalities during weaning deserve particular attention. Increasing heart rate, inverted T waves, or acute ST-segment elevation may indicate myocardial ischemia associated with the increased workload of spontaneous breathing. In such a situation, the weaning attempt should be stopped.

Appropriate ventilatory support should be restored, oxygen should be administered as needed, the patient should be monitored closely, and the physician should be notified immediately. Further weaning should generally be delayed until the cardiac abnormality has been evaluated and the patient’s condition has improved.

Complications During Airway Clearance Therapy

Airway clearance procedures can produce significant complications.

These may include:

• Hypoxemia
• Hypotension
• Increased intracranial pressure
• Pulmonary hemorrhage
• Bronchospasm
• Vomiting
• Aspiration
• Arrhythmias
• Musculoskeletal pain or injury

Note: When serious complications develop, the procedure should be stopped.

Hypoxemia

If significant hypoxemia occurs during airway clearance, stop the therapy and return the patient to an appropriate resting position. Administer or increase oxygen as needed and reassess the patient.

The physician should be consulted when the event is clinically significant or requires modification of the treatment plan.

Pulmonary Hemorrhage

Pulmonary hemorrhage requires immediate discontinuation of the airway clearance procedure. The airway should be maintained, oxygen should be administered, and the physician should be notified promptly.

Because bleeding into the airway can compromise both ventilation and oxygenation, this should be treated as a potentially serious event.

Vomiting and Aspiration

If the patient vomits and aspirates during therapy, stop treatment immediately.

The therapist may need to:

• Reposition the patient
• Clear the airway
• Suction secretions
• Administer oxygen
• Maintain airway patency
• Monitor oxygenation and ventilation

Note: The physician should then be contacted immediately because aspiration can lead to acute airway obstruction, hypoxemia, chemical pneumonitis, or subsequent infection.

Intracranial Pressure and Hypotension

If airway clearance causes a significant rise in intracranial pressure or acute hypotension, therapy should be discontinued. The patient should be returned to a stable resting position and monitored while the physician is contacted.

Pulmonary Rehabilitation and Exercise Complications

Pulmonary rehabilitation exposes patients to increased cardiopulmonary demand. Exercise may reveal abnormalities that are not obvious while the patient is resting. The therapist should monitor for excessive dyspnea, chest discomfort, abnormal heart rhythm, desaturation, unusual fatigue, dizziness, headache, nausea, and major blood pressure changes.

A severe hypertensive response requires immediate attention. For example, a patient who develops headache and nausea during exercise with a blood pressure of 220/130 mm Hg should stop exercising immediately.

The blood pressure should be documented, the patient should be monitored, and the physicians responsible for the patient’s care should be notified. Further exercise may need to be postponed until the cardiovascular abnormality has been evaluated.

Increasing Oxygen Requirements

A rising oxygen requirement can be an important sign of clinical deterioration. Patients receiving oxygen should be monitored to determine whether the prescribed device and FiO₂ are maintaining the desired saturation range.

If a patient remains hypoxemic after equipment problems have been ruled out, additional oxygen may be necessary.

When protocols allow respiratory therapists to titrate oxygen independently, the therapist may adjust therapy within the established parameters. However, a substantial or unexpected increase in oxygen requirements should still be reported to the physician because it may signal progression of the underlying disease.

Examples may include worsening:

• Pneumonia
• Pulmonary edema
• Acute respiratory distress
• Atelectasis
• Pulmonary embolism
• Airway obstruction
• Ventilation-perfusion mismatch

Note: The physician may need to order additional diagnostic testing or escalate respiratory support.

Oxygen Therapy in Neonates and Children

Oxygen administration in neonates and children requires careful control. Both inadequate and excessive oxygen can produce harmful effects, particularly in premature infants.

A written oxygen plan may establish a target SpO₂ range and specify when the physician should be contacted.

For example, a neonatal care plan may allow the therapist to adjust FiO₂ while directing physician notification if the required concentration exceeds a predetermined level such as 0.40. The exact numerical threshold depends on the care plan.

The broader principle is that increasing oxygen requirements can represent worsening disease and should be communicated according to the established protocol.

Artificial Airway and Tracheostomy Problems

Artificial airway complications can rapidly threaten ventilation and airway patency. The respiratory therapist should carefully assess tracheostomy tubes, endotracheal tubes, stomas, secretions, breath sounds, and oxygenation.

Resistance During Tracheostomy Care

Abnormal resistance during placement of a tracheostomy inner cannula should never be overcome by force. Resistance in a fenestrated tracheostomy tube may indicate that tissue is obstructing the fenestration.

The therapist should withdraw the cannula rather than forcing it into position and should notify the physician. Forcing the device could damage soft tissue or worsen airway complications.

Signs of Tracheostomy Infection

The tracheostomy stoma should also be assessed for abnormalities such as:

• Redness
• Swelling
• Purulent drainage
• Foul odor
• Skin breakdown

Note: These findings may indicate infection or another complication. The nurse and physician should be informed so that the site can be evaluated and treatment initiated if necessary.

Suspected Pleural Effusion

Respiratory assessment may reveal new findings that require physician evaluation even when no treatment complication is occurring. A patient with localized dullness to percussion and decreased breath sounds may have a pleural effusion.

The finding becomes particularly significant in patients with conditions such as congestive heart failure, malignancy, or infection.

The therapist should report suspected pleural effusion to the nurse and physician so that additional evaluation can be performed. The physician may subsequently order chest imaging, ultrasound, thoracentesis, or other testing.

Rapid Clinical Deterioration and Emergency Response

Some patients deteriorate too rapidly for ordinary physician notification alone. Hospitals often use rapid-response or medical emergency teams to intervene before cardiopulmonary arrest occurs.

Possible criteria for emergency escalation may include:

• Acute change in mental status
• Heart rate below 40 beats/min
• Heart rate above 130 beats/min
• Respiratory rate below 8 breaths/min
• Respiratory rate above 30 breaths/min
• Systolic blood pressure below 90 mm Hg
• SpO₂ below 90% despite supplemental oxygen
• Severe respiratory distress
• Major decrease in urine output
• Significant overall clinical deterioration

Exact activation criteria vary by institution. The respiratory therapist may provide oxygen, suctioning, bronchodilator therapy, noninvasive ventilation, blood gas assessment, bag-mask ventilation, or assistance with intubation.

The important principle is that severe deterioration requires immediate escalation and stabilization rather than passive waiting.

Complications During CPR

Cardiopulmonary resuscitation is another setting in which physician notification occurs alongside active emergency treatment. The therapist may recognize complications related to airway management, ventilation, arrhythmias, gastric inflation, aspiration, or other interventions.

Changes in the patient’s condition and complications associated with resuscitation should be communicated to the physician. However, CPR should not be interrupted merely to make a routine notification.

Life-saving interventions continue while communication occurs within the resuscitation team. The physician or other authorized provider ultimately makes decisions such as changing the resuscitation plan or terminating unsuccessful in-hospital CPR according to institutional policy.

When Respiratory Therapy Should Be Discontinued

Respiratory treatments should not automatically continue indefinitely simply because they were previously ordered.

There are several situations in which discontinuation may be appropriate. Treatment may no longer be needed because the patient has recovered. Therapy may also need to be discontinued when it repeatedly causes a serious adverse response.

Finally, certain therapies may be withdrawn when goals of care have changed and treatment is no longer consistent with the wishes of the patient or responsible decision-maker. The therapist should communicate these findings to the physician and participate in reassessment of the care plan.

Temporary interruption differs from permanent discontinuation. A reversible problem may allow the treatment to resume after correction. Persistent or recurrent complications may justify a permanent change in therapy.

Communication and Documentation

Proper physician notification includes more than simply making a phone call.

Communication should clearly describe:

• What changed
• When the change occurred
• Relevant vital signs
• Oxygenation or ventilation findings
• Treatments being administered
• Interventions already performed
• The patient’s response
• Important laboratory data
• Any recommendation requiring medical review

Documentation should include the clinically important findings, interventions, patient response, and the provider who was notified. Critical laboratory values, patient refusals, adverse reactions, and emergency events are particularly important to document accurately.

Clear documentation provides continuity of care and creates a record of how the patient was assessed and managed.

Exam-Focused Decision-Making

Questions involving physician notification often test the order in which actions should occur. The therapist should first determine the urgency of the problem.

Life-Threatening Emergency

If the patient has an immediate threat to airway, breathing, or circulation:

• Begin appropriate stabilization.
• Stop harmful therapy.
• Activate emergency assistance when indicated.
• Notify the physician as part of ongoing management.

Serious Adverse Reaction

If treatment causes a significant complication:

• Stop or pause the causative therapy.
• Assess and stabilize the patient.
• Notify the physician.
• Do not resume therapy until it is safe or additional instructions are received.

Questionable Physician Order

If an order appears incomplete or unsafe:

• Do not administer the questionable therapy.
• Contact the physician for clarification.
• Proceed only after the order has been appropriately addressed.

Patient Refusal

If a competent patient refuses treatment:

• Determine the reason.
• Explain the purpose and potential consequences.
• Respect the patient’s decision.
• Notify the nurse or physician.
• Document the refusal.

Minor Reversible Reaction

If the patient experiences a minor problem:

• Pause the therapy.
• Correct the problem.
• Reassess the patient.
• Resume treatment when appropriate.

Note: Physician notification may not be necessary if the problem is minor, resolves completely, and does not require a change in the care plan.

Persistent or Recurrent Adverse Response

If the same significant reaction repeatedly occurs:

• Stop the treatment.
• Stabilize the patient.
• Notify the physician.
• Recommend reassessment of the treatment plan.

Note: The provider may decide to reduce a medication dose, use another therapy, or permanently discontinue the intervention.

Notifying the Physician Practice Questions

1. When should a respiratory therapist notify the physician about a critical laboratory value?
When the laboratory result is substantially outside the expected range and may represent a potentially life-threatening condition, the therapist should promptly notify the responsible physician or provider.

2. What should a respiratory therapist do after receiving a critical laboratory result by telephone?
The therapist should verify the result using a read-back process, communicate the finding to the responsible provider, and document the notification in the medical record.

3. What should the respiratory therapist do if a physician orders a medication dose that appears dangerously high?
The therapist should withhold the questionable dose and contact the physician for clarification rather than administering it or independently changing the dose.

4. Should a respiratory therapist independently correct an order that appears to contain an error?
No. The therapist should contact the prescribing physician or provider to clarify or correct the questionable order.

5. What should a respiratory therapist do if a competent patient refuses a prescribed respiratory treatment?
The therapist should determine the reason for the refusal, explain the purpose and potential consequences of refusing therapy, respect the patient’s decision, notify the nurse or physician, and document the refusal.

6. A patient becomes severely hypoxemic during a respiratory treatment. Should notifying the physician be the therapist’s first action?
Not necessarily. The therapist should first stop the causative treatment when appropriate and stabilize the patient’s oxygenation, then promptly notify the physician.

7. What general sequence should be followed when a serious adverse reaction develops during respiratory therapy?
Stop or pause the causative treatment, remain with the patient, assess and stabilize the patient, obtain assistance if needed, notify the physician, reassess, and document the event.

8. During aerosolized bronchodilator therapy, a patient’s heart rate increases approximately 20% above baseline. What should the therapist do?
The therapist should recognize the increase as clinically significant, assess the patient, pause or stop treatment as appropriate, and notify the physician if the adverse response is significant or persistent.

9. What should the respiratory therapist do if significant tachycardia returns after aerosol therapy is restarted?
The treatment should be stopped, the patient should be monitored, and the physician should be notified regarding further therapy.

10. A patient develops new premature ventricular contractions during a respiratory procedure. What is the appropriate response?
Stop the procedure when appropriate, assess and stabilize the patient, administer supplemental oxygen if needed, and notify the physician promptly.

11. What should be done if a patient develops atrial fibrillation during respiratory therapy?
The therapist should stop the treatment, assess and stabilize the patient, and notify the physician because the new arrhythmia may represent a significant adverse response.

12. A patient develops difficulty breathing while receiving a newly administered inhaled medication. What should the therapist do?
Stop the medication, assess and support the patient’s airway and breathing, obtain emergency assistance if necessary, and notify the physician and nurse.

13. What should the respiratory therapist do if significant bronchospasm develops during aerosol therapy?
The therapist should discontinue the treatment, administer or increase oxygen as needed, monitor the patient, and notify the physician regarding additional treatment.

14. Does dizziness caused by hyperventilation during incentive spirometry always require immediate physician notification?
No. The therapist can temporarily stop the procedure, allow the patient to recover, reassess the patient, and resume the therapy more slowly if the symptoms completely resolve.

15. A mechanically ventilated patient develops decreasing blood pressure and increasing heart rate after PEEP is increased. What should the therapist suspect?
The therapist should suspect decreased venous return and cardiac output caused by increased intrathoracic pressure and should assess the patient and notify the physician if significant hemodynamic deterioration is occurring.

16. What should the respiratory therapist do when a patient develops sustained signs of intolerance during a spontaneous breathing trial?
The patient should be returned to appropriate ventilatory support, reassessed, and the results should be communicated to the physician or responsible provider.

17. During ventilator weaning, a patient develops increasing heart rate and acute ST-segment elevation. What is the appropriate response?
Stop the weaning trial, restore appropriate ventilatory support, provide oxygen as indicated, closely monitor the patient, and notify the physician immediately.

18. What should be done if significant hypoxemia develops during airway clearance therapy?
Stop the treatment, return the patient to an appropriate resting position, administer or increase oxygen as necessary, reassess the patient, and consult the physician.

19. A patient develops pulmonary hemorrhage during airway clearance therapy. What should the respiratory therapist do?
Immediately discontinue the treatment, maintain the airway, administer oxygen as needed, monitor the patient, and promptly notify the physician.

20. What should the respiratory therapist do if a patient vomits and aspirates during airway clearance therapy?
Stop the treatment, reposition the patient, clear and suction the airway as needed, administer oxygen, maintain airway patency, and contact the physician immediately.

21. A patient undergoing pulmonary rehabilitation develops headache and nausea with a blood pressure of 220/130 mm Hg. What should the therapist do?
Stop the exercise, monitor and document the patient’s condition, and immediately notify the physicians responsible for the patient’s care.

22. Why should a significant increase in a patient’s oxygen requirement be reported to the physician?
An increasing oxygen requirement may indicate worsening gas exchange or progression of the underlying disease and may require additional evaluation or changes in treatment.

23. A neonatal oxygen protocol states that the physician should be contacted if the required FiO₂ exceeds 0.40. What should the therapist do when the infant requires an FiO₂ of 0.45?
The therapist should provide oxygen according to the established plan and notify the physician because the oxygen requirement has exceeded the specified threshold.

24. During insertion of an inner cannula into a fenestrated tracheostomy tube, the therapist encounters unexpected resistance. What should be done?
The therapist should not force the inner cannula. It should be withdrawn, and the physician should be notified because tissue may be obstructing the fenestration.

25. During routine tracheostomy care, the therapist notices redness, swelling, purulent drainage, and a foul odor around the stoma. What should be done?
The therapist should recognize these findings as possible signs of infection and notify the nurse and physician so the site can be evaluated and appropriate treatment initiated.

26. What should the respiratory therapist do if a major contraindication to a prescribed respiratory treatment is identified before therapy begins?
The therapist should withhold the treatment and contact the prescribing physician for clarification or guidance before proceeding.

27. Why is a sudden increase in FiO₂ requirement clinically important even if oxygen saturation can still be maintained?
Because the higher oxygen requirement may indicate worsening gas exchange or progression of the patient’s underlying condition and may require a change in the treatment plan.

28. What should the therapist do if a patient develops a significant increase in intracranial pressure during airway clearance therapy?
The therapist should stop the treatment, return the patient to an appropriate resting position, monitor the patient, and consult the physician.

29. A patient develops acute hypotension during chest physiotherapy. What is the appropriate response?
Stop the therapy, place the patient in an appropriate resting position, assess and stabilize the patient, and notify the physician.

30. What should the respiratory therapist do if a patient develops severe musculoskeletal pain during an airway clearance procedure?
The therapist should stop the portion of therapy causing the problem, move the patient cautiously, assess for possible injury, and consult the physician.

31. A patient develops new stridor during a respiratory treatment. What should the therapist do?
The therapist should stop the treatment, assess airway patency, provide appropriate respiratory support, and notify the physician promptly.

32. What should the therapist do if a patient develops hemoptysis during a respiratory procedure?
The therapist should stop the procedure, assess the amount and severity of bleeding, maintain oxygenation and airway patency, and notify the physician.

33. Why should a new change in mental status during respiratory therapy be taken seriously?
Because altered mental status may indicate hypoxemia, hypercapnia, poor perfusion, medication effects, or other significant deterioration that requires immediate assessment and possible physician notification.

34. A patient receiving respiratory therapy suddenly becomes diaphoretic, pale, and increasingly dyspneic. What should the therapist do?
The therapist should stop the therapy, remain with the patient, assess vital signs and oxygenation, stabilize the patient, and notify the physician or activate emergency assistance if necessary.

35. What should the therapist do if a patient’s SpO₂ falls below 90% despite supplemental oxygen?
The therapist should assess the patient immediately, correct reversible causes, increase respiratory support as appropriate, and escalate care by notifying the physician or activating a rapid-response system if indicated.

36. What should be done if a patient’s respiratory rate rises above 30 breaths/min with signs of worsening distress?
The therapist should promptly assess and stabilize the patient and consider emergency escalation or physician notification because this may indicate significant clinical deterioration.

37. Why should a systolic blood pressure below 90 mm Hg during respiratory care prompt concern?
Because hypotension may indicate hemodynamic instability, reduced perfusion, or a serious treatment complication that requires immediate assessment and possible physician notification.

38. What should the therapist do if a patient develops a heart rate above 130 beats/min along with respiratory distress?
The therapist should assess and stabilize the patient, stop any therapy contributing to the problem, and notify the physician or activate an emergency response if the deterioration is severe.

39. What should be done if a patient develops a heart rate below 40 beats/min during respiratory treatment?
The therapist should stop the treatment, assess the patient’s airway, breathing, circulation, and level of consciousness, and obtain immediate medical assistance while notifying the physician.

40. What should the therapist do if a patient develops a substantial drop in SpO₂ during therapy but the equipment appears to be functioning correctly?
The therapist should treat the desaturation as a clinical problem, reassess the patient, provide appropriate oxygen or ventilatory support, and notify the physician if the change is significant.

41. A patient receiving respiratory therapy develops severe fatigue and can no longer perform the procedure effectively. What should the therapist do?
The therapist should stop the treatment, allow the patient to rest, reassess the patient’s condition, and notify the physician if the fatigue suggests the current therapy is no longer safe or effective.

42. When should a respiratory therapist recommend that a treatment be permanently discontinued?
When the treatment is no longer needed, repeatedly causes a serious adverse reaction, or is being withdrawn in accordance with the patient’s goals of care and the physician’s plan.

43. What is the difference between temporarily pausing a treatment and permanently discontinuing it?
A temporary pause allows a reversible problem to be corrected before therapy resumes, while permanent discontinuation is considered when the treatment is no longer needed or continues to cause significant harm.

44. What should the therapist do if repeated doses of the same medication consistently cause significant tachycardia?
The therapist should stop the treatment, monitor the patient, notify the physician, and recommend reassessment of the medication dose or selection of an alternative therapy.

45. Why should the therapist notify the physician when assessment findings suggest a pleural effusion?
Because findings such as localized dullness to percussion and decreased breath sounds may indicate a new condition that requires diagnostic evaluation and possible treatment.

46. What should the therapist do if a patient with suspected pleural effusion is otherwise stable?
The therapist should document the assessment findings and notify the nurse and physician so the patient can be further evaluated.

47. During tracheostomy care, why should the therapist assess breath sounds and oxygenation after completing the procedure?
Because changes in breath sounds or oxygenation may indicate airway obstruction, tube displacement, retained secretions, or another complication that may require immediate intervention and physician notification.

48. What should the therapist do if a significant complication develops during CPR-related airway management?
The therapist should continue necessary resuscitative interventions, correct the complication when possible, and communicate the change to the physician or resuscitation team without interrupting lifesaving care.

49. Why should the therapist not delay emergency treatment while attempting to contact the physician?
Because immediate threats to airway, breathing, circulation, or oxygenation require prompt intervention, and delaying stabilization could worsen the patient’s condition.

50. What information should be documented after notifying the physician about a significant respiratory event?
The therapist should document the abnormal finding, relevant assessment data, interventions performed, the patient’s response, the time of notification, and the name or role of the provider who was contacted.

51. A patient receiving aerosol therapy develops new chest pain but remains conscious and hemodynamically stable. What should the therapist do?
The therapist should stop the treatment, assess the patient, monitor vital signs and oxygenation, and notify the physician because new chest pain may indicate a significant cardiovascular problem.

52. Why should the therapist reassess a patient after stopping a treatment because of an adverse reaction?
Reassessment helps determine whether the patient is improving, whether additional intervention is needed, and whether the therapy can be safely resumed or should remain discontinued.

53. A patient with chronic respiratory disease suddenly requires a higher level of ventilatory support than earlier in the shift. Why should the physician be informed?
Because an unexpected increase in ventilatory support may indicate worsening respiratory failure or progression of the underlying disease and may require changes in the treatment plan.

54. What should the respiratory therapist do if a patient becomes confused shortly after a ventilator adjustment?
The therapist should assess oxygenation, ventilation, vital signs, and ventilator function, correct any immediate problem, and notify the physician if the mental status change persists or is clinically significant.

55. A patient receiving chest physiotherapy develops a new cardiac arrhythmia. What is the appropriate response?
The therapist should stop the therapy, assess and stabilize the patient, administer oxygen if indicated, and notify the physician promptly.

56. Why is a persistent adverse response more concerning than a brief, easily corrected treatment reaction?
A persistent adverse response suggests that the therapy may be unsafe or inappropriate and may require physician-directed modification or discontinuation.

57. What should the therapist do if a patient becomes cyanotic during a respiratory procedure?
The therapist should stop the procedure, assess airway and breathing, provide oxygen or ventilatory support as needed, obtain help, and notify the physician once immediate stabilization is underway.

58. A patient repeatedly becomes severely dyspneic each time a prescribed treatment is attempted. What should the therapist do?
The therapist should stop the treatment, stabilize the patient, notify the physician, and recommend reassessment of whether the therapy should be modified or discontinued.

59. Why should changes in breath sounds during therapy be taken seriously?
New wheezing, stridor, markedly decreased breath sounds, or other significant changes may indicate bronchospasm, obstruction, pneumothorax, or another complication that could require immediate intervention and physician evaluation.

60. What should the therapist do if a patient develops sudden hypotension after a major ventilator setting change?
The therapist should assess the patient and ventilator immediately, provide appropriate stabilization, evaluate whether the setting change contributed to the problem, and notify the physician.

61. A patient is alert and competent but refuses suctioning despite retained secretions. What should the therapist do?
The therapist should explain the purpose and potential consequences of refusing suctioning, respect the patient’s decision, document the refusal, and notify the nurse or physician.

62. Why should patient education be provided before documenting a treatment refusal?
Education helps ensure that the patient understands the purpose, benefits, and possible consequences of refusing therapy before making an informed decision.

63. A patient refuses therapy because of a language barrier and appears not to understand the explanation. Should this immediately be treated as a final refusal?
No. The therapist should first address the communication barrier, such as by obtaining an interpreter or appropriate communication assistance, before concluding that the patient has made an informed refusal.

64. What should the therapist do if a respiratory treatment order is missing essential information such as the medication dose or frequency?
The therapist should contact the prescribing provider for clarification before administering the treatment.

65. Why is it inappropriate for a respiratory therapist to guess what an incomplete order was intended to mean?
Guessing can result in medication or treatment errors. The order should be clarified with the prescribing provider so the intended therapy is clearly established.

66. A patient develops marked wheezing and decreasing oxygen saturation shortly after a medication is started. What should the therapist suspect?
The therapist should suspect a serious adverse respiratory reaction, stop the medication, assess and stabilize the patient, and notify the physician.

67. What should the therapist do if a medication-related adverse reaction resolves after the treatment is stopped?
The patient should still be reassessed, and the physician should be notified when the reaction was significant because the medication plan may need to be changed before another dose is given.

68. Why might a respiratory therapist notify the physician even when a patient is not in immediate danger?
The physician may still need to evaluate a new abnormality, clarify an order, modify therapy, investigate a suspected diagnosis, or address a persistent treatment problem.

69. A patient undergoing exercise in pulmonary rehabilitation develops a new irregular pulse without severe symptoms. What should the therapist do?
The therapist should stop the exercise, assess the patient’s rhythm, vital signs, and symptoms, and notify the physician because a new rhythm abnormality requires evaluation.

70. Why should respiratory therapists monitor more than oxygen saturation during pulmonary rehabilitation?
Exercise can reveal cardiovascular, neurologic, and systemic problems such as arrhythmias, hypertension, hypotension, chest symptoms, dizziness, headache, or nausea that may require physician evaluation.

71. A patient on oxygen therapy remains below the prescribed saturation goal after equipment problems are ruled out. What should the therapist do?
The therapist should increase oxygen if permitted by protocol, reassess the patient, and notify the physician if the patient requires a significant increase in oxygen or remains hypoxemic.

72. When should a therapist contact the physician instead of independently increasing oxygen?
The physician should be contacted when institutional policy or the prescription does not allow independent titration, when the needed increase exceeds protocol limits, or when the patient’s condition is significantly worsening.

73. Why is documentation important after a significant treatment complication?
Documentation creates an accurate record of the event, the patient’s condition, interventions performed, response to treatment, and communication with the physician or other providers.

74. What should the therapist document when a questionable order is clarified with the physician?
The therapist should document the clarification or corrected order according to institutional policy, including relevant communication and any resulting change in treatment.

75. What is the main clinical principle behind deciding when to notify the physician in respiratory care?
The therapist should recognize significant changes, protect the patient from immediate harm, stabilize urgent problems, and notify the physician whenever a new medical decision or change in the treatment plan may be needed.

76. A patient develops severe anxiety and diaphoresis during a spontaneous breathing trial, but oxygen saturation remains acceptable. What should the therapist do?
The therapist should recognize these findings as possible signs of weaning intolerance, stop or shorten the trial as appropriate, return the patient to ventilatory support, and communicate the findings to the physician.

77. Why should acute ST-segment changes during ventilator weaning be treated seriously?
Because they may indicate myocardial ischemia caused by the increased cardiovascular workload of spontaneous breathing and require prompt termination of the trial and physician evaluation.

78. A patient receiving airway clearance therapy suddenly becomes hypotensive and light-headed. What is the appropriate response?
The therapist should stop the treatment, place the patient in a safe resting position, assess vital signs and oxygenation, stabilize the patient, and notify the physician.

79. What should the therapist do if airway clearance therapy causes a significant increase in intracranial pressure?
The treatment should be discontinued, the patient should be returned to an appropriate position, and the physician should be consulted regarding further therapy.

80. A patient develops bronchospasm during chest physiotherapy. What should the respiratory therapist do?
The therapist should stop the therapy, assess the patient, administer or increase oxygen as needed, and notify the physician. A prescribed bronchodilator may be administered if appropriate.

81. Why should pulmonary hemorrhage during airway clearance therapy prompt immediate physician notification?
Because active bleeding can compromise airway patency, ventilation, and oxygenation and may require urgent medical intervention.

82. A patient aspirates gastric contents during a respiratory procedure but is still breathing spontaneously. What should the therapist do first?
The therapist should immediately stop the procedure and protect the airway by repositioning and suctioning as needed, then provide oxygen and notify the physician.

83. What should the therapist do if a patient’s respiratory treatment repeatedly produces significant hypotension?
The treatment should be stopped, the patient stabilized, and the physician notified so the therapy can be reassessed or modified.

84. A patient develops severe rib pain during percussion therapy. What should the therapist do?
The therapist should stop the procedure, assess the patient for possible musculoskeletal injury, move the patient cautiously, and consult the physician.

85. Why can a large change in blood pressure during respiratory therapy require physician notification?
A major blood pressure change may indicate hemodynamic instability, a treatment complication, or another significant clinical problem requiring medical evaluation.

86. A neonatal patient requires progressively higher FiO₂ to maintain the prescribed SpO₂ range. What does this trend suggest?
It may indicate worsening gas exchange or progression of the infant’s underlying condition and should be communicated according to the prescribed oxygen plan.

87. Why should oxygen therapy in neonates be carefully titrated rather than increased without limits?
Both inadequate and excessive oxygen can be harmful, so therapy should follow a prescribed saturation range and physician-notification thresholds.

88. During routine tracheostomy care, the therapist finds foul-smelling drainage but the patient has stable vital signs. Is physician notification still appropriate?
Yes. Foul-smelling drainage may indicate infection or another local complication and should be reported to the nurse and physician for evaluation.

89. What should a respiratory therapist do if breath sounds are markedly reduced after tracheostomy care compared with the preprocedure assessment?
The therapist should reassess airway patency, tube position, oxygenation, and secretions, correct any immediate problem, and notify the physician if the abnormality persists or is significant.

90. Why should a therapist avoid forcing an airway device when unexpected resistance is encountered?
Forcing the device can cause tissue injury, bleeding, airway trauma, or worsening obstruction, so the attempt should be stopped and medical assistance obtained.

91. A patient develops localized dullness to percussion and diminished breath sounds at the lung base. What should the therapist do?
The therapist should recognize these findings as potentially consistent with pleural fluid, document the assessment, and notify the nurse and physician for further evaluation.

92. What is the role of the respiratory therapist when a rapid-response team is activated for respiratory deterioration?
The therapist may assess airway and breathing, provide oxygen, suction the airway, administer indicated respiratory treatments, assist with noninvasive ventilation, obtain blood gases, and prepare for advanced airway management.

93. Why is routine physician notification alone insufficient for a patient who is rapidly approaching respiratory arrest?
Because the patient requires immediate emergency intervention and escalation of care rather than waiting for a routine physician response.

94. A patient becomes unresponsive and severely bradycardic during respiratory therapy. What should the therapist do?
The therapist should immediately assess airway, breathing, and circulation, activate the appropriate emergency response, begin indicated lifesaving interventions, and communicate with the physician as part of the emergency response.

95. What should the therapist do if a patient develops severe hypoxemia despite increasing supplemental oxygen?
The therapist should rapidly assess the cause, provide additional ventilatory support as indicated, activate emergency assistance when appropriate, and notify the physician because the patient may require escalation of respiratory care.

96. Why should the therapist report an adverse reaction even if the patient recovers quickly after treatment is stopped?
A significant reaction may recur with future treatments and may require the physician to modify the medication, dosage, procedure, or overall treatment plan.

97. What should the therapist do when a prescribed therapy is no longer producing a clinical benefit?
The therapist should reassess the patient, document the lack of effectiveness, and communicate the findings to the physician so the treatment plan can be reviewed.

98. A patient has recovered from an acute respiratory condition and appears to no longer need a previously ordered treatment. What should the therapist do?
The therapist should reassess the indication for therapy and communicate with the physician or follow an approved protocol regarding discontinuation rather than continuing unnecessary treatment indefinitely.

99. What should the therapist include when reporting a significant clinical change to the physician?
The report should include the patient’s current condition, relevant vital signs, oxygenation and ventilation data, recent changes, interventions already performed, and the patient’s response.

100. How can a respiratory therapist decide whether to stabilize the patient first or notify the physician first?
If the patient has an immediate threat to airway, breathing, circulation, or oxygenation, stabilization and emergency intervention take priority. If the problem is nonemergent but requires a medical decision, the physician should be contacted promptly for guidance.

Final Thoughts

Knowing when to notify the physician requires clinical judgment rather than memorizing a single rule. Respiratory therapists should communicate critical values, serious adverse reactions, important assessment changes, treatment failures, increasing respiratory support requirements, patient refusals, questionable orders, and significant complications.

However, notification should never delay immediate stabilization when a patient is actively deteriorating. The therapist must first recognize the problem, stop harmful therapy when appropriate, protect airway and breathing, obtain assistance, and then communicate the findings clearly.

Effective respiratory care depends on assessment, timely intervention, professional communication, reassessment, and accurate documentation.
