Postural Drainage Positions and Chest Physiotherapy (CPT) Study Guide

So if you’re ready, let’s go ahead and dive right in.

What is Airway Clearance Therapy?

Airway Clearance Therapy uses noninvasive techniques to help mobilize and remove secretions in order to improve gas exchange.

There are several that fall into this type of therapy but this guide is specifically focused on Postural Drainage and Chest Physiotherapy.

What is Chest Physiotherapy?

It is a form of Airway Clearance Therapy that is generally performed by a Respiratory Therapist with the goal of clearing mucus from the airways and lungs. It involves striking the lungs manually with your hands, with a cuff, or with an automatic percussor. 

The rhythmic strikes and vibrations help loosen secretions from the airways. Then you can help propel them forward by placing the patient in various postural drainage positions using gravity. 

What is Postural Drainage?

It is a form of Airway Clearance Therapy that involves placing the patient’s body in various positions in order to drain secretions from the lung segments into the central airways using gravity. From there, the secretions can be removed via cough or suctioning.

Postural Drainage Positions:

The following tables break down every Postural Drainage Position that is needed in order to drain each specific lobe or segment of the lungs.

Postural Drainage Positions Image:

Hopefully you can use this illustration to help make learning the Postural Drainage Positions much easier.

Postural Drainage Indications:

• To mobilize retained secretions so that they can be suctioned or expectorated
• Cystic Fibrosis
• Atelectasis
• Bronchiectasis
• Foreign body obstruction

Postural Drainage Contraindications:

There are certain situations in which Postural Drainage would not be recommended. Here are some examples:

• Head, neck, or spinal injury
• Hemodynamic instability
• Increased intracranial pressure
• Hemoptysis
• Bronchopleural fistula
• Pulmonary edema as a result of CHF
• Pleural effusion
• Flail Chest

Is Postural Drainage Used to Treat Cystic Fibrosis?

Yes, Postural Drainage is an effective method that is used to treat patients with Cystic Fibrosis.

With that said, other forms of Airway Clearance Therapy can be used as well and no one method has been proven to be more effective than others. It all depends on the patient’s preference. In general, you should select the method that will be most tolerated by the patient.

What is the Chest Physiotherapy Vest?

After wearing the vest for a period of time, usually 5 minutes, the therapy is paused so that the patient can attempt to cough and remove mucus from the lungs.

Chest Physiotherapy Indications:

Chest Physiotherapy should only be recommended for certain patients under certain conditions. Here are some examples:

• To mobilize retained secretions so that they can be suctioned or expectorated
• Cystic Fibrosis
• Atelectasis
• Bronchiectasis
• Foreign body obstruction
• Lung abscess
• Neuromuscular diseases

Chest Physiotherapy Contraindications:

There are certain situations in which Chest Physiotherapy would not be recommended. Here are some examples:

• Head, neck, or spinal injury
• Hemodynamic instability
• Increased intracranial pressure
• Hemoptysis
• Rib fractures or flail chest
• Vertebral fractures
• Osteoporosis

More Practice Questions About Chest Physiotherapy and Postural Drainage:

Clearance techniques, exercise protocols, and breathing retaining methods.

8. How long should each postural drainage be held?
3–5 minutes for each position.

9. What is the procedure for performing chest wall percussion and vibration?
Percussion – Cupping over the lung segment. Have the patient do purse lip breathing. Vibration – is done after percussion and you should vibrate towards the carina. Be sure to have the patient inhale and then perform the vibration while they are exhaling.

Lying supine with a pillow under the legs.

14 What is the position for the left lingual (left lower)?
Raise the bed about 12 inches (on the feet) (Trendelenburg) with the left arm and back raised.

15. What is the position for the posterior segments (lower lobes)?
Legs raised about 18 inches (30 degrees) (Trendelenburg). Prone with a pillow under the stomach.

16. What is the position for the superior segments (middle)?
Prone with a pillow under the stomach.

17. What are the contraindications for postural drainage?
An unstabilized head or neck injury, hemorrhage, hemoptysis, rib fracture, flail chest, surgical wound, and a pulmonary embolism.

18. What are the contraindications for percussion and vibration?
Recent pacemaker placement, lung contusion, blood clotting, burns, wounds, osteoporosis, and chest wall pain.

19. When you have a patient is hooked up to an EKG, IV, or other device, what do you do before administering CPT?
Notify the nurse and/or monitor technician.

20. What should be charted after completing CPT?
The position and time, sputum amount, tolerance, and any problems that occurred.

21 What are some adverse reactions that can occur during CPT?
Hypoxemia, increased ICP, acute hypotension, pulmonary hemorrhage, pain, vomiting, aspiration, bronchospasm, and arrhythmias.
