Are you ready to learn about the different types of abnormal and irregular breathing patterns? If so, then you’re in the right place, because that is what this article is all about.

Below, we’ve listed out the most common breathing patterns that you must be familiar with while working as a Respiratory Therapist or medical professional.

There are 3 primary reasons that you need to learn and understand the different breathing patterns:

  1. Because you will be tested on this information in Respiratory Therapy School.
  2. Because you will see this information again when you take the TMC Exam and Clinical Sims.
  3. Because you will need to recognize the breathing patterns once you start seeing your own patients.
So taking that into consideration, you can easily see the importance of mastering the breathing patterns — especially the irregular ones.

That good news is, this study guide can help you do just that. So if you’re ready, let’s go ahead and dive right in.

What is a Breathing Pattern?

As humans, our breathing pattern is similar to our heartbeat in that we do not have to consciously think about it — it just occurs automatically. This response is generated by the medullary respiratory center in the brain.

Although this stimulus comes from the brain, there are quite a few conditions that can abnormal and irregular breathing patterns. We are going to talk about those below.

Types of Breathing Patterns that you must know as a Respiratory Therapist:

Breathing PatternDescriptionAssociated Conditions
EupneaNormal breathing, including a normal respiratory rate (12 -20 breaths per minute), depth, and rhythm.Normal, healthy people.
TachypneaIncreased respiratory rate greater than 20 breaths per minute.Hypoxemia, respiratory distress, fever, pain, anxiety.
BradypneaDecreased respiratory rate less than 12 breaths per minute.Sedation, alcohol, fatigue, drug overdose.
ApneaNo breathing.Cardiac arrest, respiratory arrest, airway obstruction, drug overdose, sleep apnea.
HyperpneaIncreased respiratory rate, rhythm, and depth of breathing.CHF, metabolic or CNS disorders.
Cheyne-stokesAn abnormal breathing pattern with periods of progressively deeper breaths alternating with periods of shallow breathing and apnea.Increased intracranial pressure, brain stem injuries.
Biot’sBreathing characterized by irregular periods of apnea alternating with periods in which four or five breaths of identical depth are taken. Similar to Cheyne-Stokes except that each breath has the SAME depth.Increased intracranial pressure, meningitis.
Kussmaul’sRemember: DEEP and FAST. Increased respiratory rate and depth, with an irregular rhythm. This is a labored form of breathing that is usually associated with diabetic ketoacidosis.Diabetic ketoacidosis, renal failure.
ApneusticAn abnormal pattern of breathing characterized by deep, gasping inspiration with a pause at full inspiration followed by a brief, insufficient release.Head trauma, severe brain hypoxia, lack of blood flow to the brain.
OrthopneaDifficulty breathing while lying down.CHF, fluid overload, chronic lung disease.

Practice Questions about Breathing Patterns:

1. What is the best technique to assess a patient’s respirations accurately?
Place a hand on the upper abdomen and observe the rise and fall of the chest.

2. What is Apnea?
It is the complete absence of breathing.

3. What is Eupnea?
Normal breathing.

4. What is Biot’s Breathing?
Short episodes of rapid, uniformly deep inspirations, followed by 10-30 seconds of apnea. It is most often seen in patients with meningitis.

5. What is Hyperpnea?
Increased depth (volume) of breathing with or without an increased frequency.

6. What is Hyperventilation?
An increased rate or depth of breathing that causes an increase in CO2.

7. What is Tachypnea?
A rapid rate of breathing when the respiratory rate is greater than 24.

8. What is Cheyne-Stokes Breathing?
It is a gradual increase and then a decrease in the rate and volume of breathing, followed by 5-10 seconds of apnea. It most often occurs in patients with cerebral disorders and CHF.

9. What is Kussmaul’s Breathing?
Both an increased depth (hyperpnea) and rate of breathing. With this pattern, the CO2 decreases, while the oxygen increases.

10. What is Orthopnea?
A condition in which an individual is able to breathe most comfortably only in an upright position. They have difficulty breathing while lying down.

11. What is Dyspnea?
Difficulty in breathing, of which the individual is aware. It is also called – shortness of breath.

12. What is the purpose of pursed-lip breathing?
To prevent the air trapping caused by bronchiolar airway collapse by increasing the back pressure; it also helps to aid with panic attacks.

13. How do you perform pursed-lip breathing?
Take a deep breath in and hold; then breathe out with your lips puckered like you’re blowing out a candle.

14. The physiological effects of pursed-lip breathing will do what?
It will decrease the patient’s respiratory rate by increasing the expiratory rate.

15. What are the diseases that are helped with pursed lip breathing?
COPD and emphysema.

16. What is the purpose of abdominal diaphragmatic breathing exercises?
This promotes a greater use of the diaphragm, decreases the work of breathing by slowing your breathing rate, decreases oxygen demand, uses less effort and energy to breathe, and helps to prevent atelectasis.

17. What is a disease that will benefit from diaphragmatic breathing?
COPD

18. What is lateral costal breathing?
Unilateral or bilateral costal breathing exercises increase ventilation to the lower lobes and aid in diaphragmatic breathing.

19. What patients use lateral costal breathing?
Post-surgery, pregnancy, or ascites patients.

20. What are the purposes of breathing exercises?
To promote efficient use of the diaphragm, to decrease the use of the rib cage, and to improve cough and the efficiency of ventilation.

21. What are the 4 phases of a cough?
Irritation, inspiration, compression, and expulsion.

22. What is a direct cough?
A deliberate maneuver that is taught, supervised, and monitored.

23. What is the incentive spirometer technique?
A technique using visual feedback to encourage patients to take a slow, deep sustained inspiration.

24. What is a sustained maximal inspiration?
A method to get the patient to hole the inspiratory effort as long as possible.

25. What is Apneustic Breathing?
A prolonged inspiration and a regular expiration. It is caused by a brain injury.

26. What is Paradoxical Breathing?
The chest depresses on inspiration, and on expiration, the chest puffs. It is caused by a chest injury.

27. How would you describe asthmatic breathing?
A prolonged expiration and a regular inspiration.

28. What is Platypnea?
When the patient can breathe better when laying down.

29. What is Orthopnea?
When the patient can breathe better when sitting up.

30. What can result from hypoventilation?
Hypercapnia.

31. What does hypercapnia mean?
Increases arterial PCO2.

32. How is hypercapnia counteracted?
By an increased ventilation rate and depth.

33. What is hyperventilation?
An increased ventilation rate and depth.

34. What can hyperventilation cause?
Hypocapnia.

35. What can hypocapnia cause?
A decrease in the arterial PCO2.

36. Which of the following breathing patterns is MOST indicative of increased intracranial pressure?
Cheyne-Stokes and Biot’s breathing.

Final Thoughts

Again, I just want to thank you for taking the time to read through this study guide about the abnormal and irregular breathing patterns in Respiratory Care.

You’re an action-taker! And I like that!

This gives me a good feeling that you are going to have a very successful career as a medical professional. Keep working and studying hard — it’s going to pay off for you in a big way.

Thanks again for reading and as always, breathe easy, my friend!
