Postural Drainage Positions and Chest Physical Therapy (CPT)

Postural drainage and chest physical therapy (CPT) are essential therapeutic techniques used to help clear mucus from the lungs, particularly in patients with respiratory conditions such as cystic fibrosis, bronchiectasis, or chronic bronchitis.

These methods use gravity-assisted body positioning and manual techniques—like percussion and vibration—to mobilize secretions and improve airway clearance.

Understanding the proper positions and techniques is crucial for both healthcare professionals and patients, as they play a vital role in preventing infections, improving breathing, and enhancing overall lung function.

 

 

Understanding Postural Drainage and Chest Physical Therapy

Postural drainage and chest physical therapy help remove secretions from the lungs using specific body positions and manual techniques. They are used to improve lung function and prevent complications from retained mucus.

Definition and Purpose

Postural drainage involves placing the patient’s body in various positions so gravity helps move mucus from the smaller airways toward the larger ones. This approach makes it easier for patients to cough out or suction the secretions.

Chest physical therapy (CPT) includes techniques like percussion, vibration, and coughing. The primary goal is to clear mucus from the airways, enhancing breathing. These interventions can also reduce infection risk and relieve symptoms in chronic lung conditions.

Healthcare providers tailor these techniques based on the patient’s needs, disease state, and physical abilities. Proper application can significantly improve symptoms and quality of life in people with respiratory problems.

Physiological Principles

Postural drainage positions optimize gravity’s effect on different segments of the lung. By positioning the lung segment to be drained higher than the trachea, mucus can flow more freely toward the central airways.

CPT techniques such as percussion and vibration loosen thick secretions. Percussion uses rhythmic clapping with cupped hands over the chest wall, while vibration involves shaking the chest during exhalation. Both methods help dislodge mucus so it can be expelled.

These methods are based on the idea that removing retained secretions prevents airway obstruction and infection. Improved airway clearance supports better gas exchange and lowers the risk of lung complications.

Patient Indications and Contraindications

Postural drainage and CPT are indicated for patients with increased mucus production or difficulty clearing secretions. Common candidates include those with cystic fibrosis, bronchiectasis, chronic bronchitis, or pneumonia.

Contraindications are important to consider. These include severe hypoxemia, unstable cardiovascular status, untreated tuberculosis, recent lung surgery, active hemoptysis, or fractured ribs. Care must be taken with patients who have osteoporosis or recent trauma.

Before starting therapy, providers assess the overall health, diagnosis, and risks to determine if it is safe and effective for the individual. Adjustments are made depending on the patient’s response and tolerance.

Key Postural Drainage Positions

Effective chest physical therapy uses targeted body positions to help move mucus from specific lung segments. These positions rely on gravity and patient orientation to improve airway clearance and support lung health.

Upper Lobe Drainage Techniques

To drain the apical segments of the upper lobes, the patient typically sits upright, sometimes leaning slightly forward. Gravity assists mucus movement toward the larger airways in this posture.

For the posterior segments of the upper lobes, sitting and leaning forward at roughly a 30-degree angle is advised. The respiratory therapist may use cupping and vibration on the upper back, between the spine and shoulder blade.

The anterior segments are best accessed by having the patient lie flat on the back with a pillow under the knees for comfort. This position helps secretions shift from the front portions of the lungs toward the central airways.

Middle Lobe and Lingula Positions

Draining the right middle lobe involves placing the patient in a side-lying position on the left side, with the body rotated slightly backward and the foot of the bed elevated about 12 inches. This angle uses gravity to move secretions upward and outward from the middle lobe.

For the lingula (the left-sided equivalent of the middle lobe), the patient lies on their right side, again with the torso rotated slightly backward and the bed’s foot elevated to a similar degree. Both positions often include slight arm extension or shoulder rotation for better access.

Proper pillow support maintains body alignment and reduces tension. Respiratory therapists commonly apply manual chest percussion and vibration in these positions to enhance effectiveness.

Lower Lobe Drainage Methods

The lower lobes require head-down positions to maximize gravity’s effect. For the anterior basal segments, the patient lies on their back, foot of bed raised 18 inches, allowing secretions to drain from lower lung fields.

Posterior basal segment drainage is achieved by lying on the abdomen, again with the lower body elevated. The therapist targets percussion over the lower back and sides.

For the lateral basal segments, side-lying is used, with the affected lung uppermost. Elevation of the bed’s foot continues to aid mucus movement. The superior segment of the lower lobe is best addressed by positioning the patient flat on the stomach without elevation, with percussion between the lower shoulder blades.

Chest Physical Therapy Techniques

Chest physical therapy (CPT) consists of hands-on techniques that help clear mucus from the lungs and airways. These methods support breathing and can be adapted to different patients’ needs, focusing on improving airway clearance.

Percussion

Percussion is performed by rhythmically clapping on the chest wall with cupped hands. This action helps loosen thick secretions in the lungs, making it easier for the patient to cough them up.

It is important to avoid clapping over the spine, breastbone, stomach, and lower ribs to prevent injury. A layer, such as a towel, is often placed between the hands and the patient’s skin for comfort. Sessions typically last 3 to 5 minutes per area, with different positions used based on the lung segments needing drainage.

The technique must be consistent and gentle but firm, adjusted for the age and condition of the patient. Parents or caregivers are often taught how to perform percussion at home.

Vibration and Shaking

Vibration and shaking are used following percussion to further help move mucus toward the larger airways. Vibration involves placing a flat hand or hands on the chest and creating a gentle, rapid shaking motion during exhalation.

Shaking is a more forceful version of vibration, done with a slightly larger movement, and is usually performed only by trained professionals. Both techniques should be synchronized with the patient’s breathing cycle, especially during exhalation, to maximize mucus movement.

Care should be taken to maintain proper hand placement and pressure to avoid discomfort or injury. These techniques are often repeated until the secretions become loose enough for the patient to cough them out effectively.

Indications

• Copious secretions
• Retained secretions
• Ineffective cough
• Cystic fibrosis
• Bronchiectasis
• Ciliary dyskinetic syndromes

Contraindications

• Neck or spinal cord injury
• Hemodynamic instability

Complications of Postural Drainage

While postural drainage is an effective airway clearance technique for patients with chronic respiratory conditions, it is not without its potential hazards and complications. Some examples include:

• Hypoxemia
• Increased intracranial pressure
• Acute hypotension
• Pulmonary hemorrhage
• Injury to muscles, ribs, or spine
• Aspiration
• Vomiting
• Bronchospasm
• Arrhythmias

How to Remember the Postural Drainage Positions

Remembering all the postural drainage positions for different lung segments can be overwhelming, especially for students and new clinicians. One helpful shortcut is to associate gravity and lung anatomy using the phrase:

Lower Lobes

• Posterior basal segment
• Lateral basal segment
• Anterior basal segment
• Superior segment

Right Middle Lobe and Left Lingula

• Right lateral and medial segments
• Left superior and inferior lingula segments

Upper Lobes

• Posterior segment
• Apical segment
• Anterior segment

Percussion and Vibration

Percussion and vibration techniques involve the use of mechanical energy on the thoracic region to loosen up secretions for easier clearance. This is performed manually by hand or with a pneumatic or electrical device.

Manual percussion, a technique performed by respiratory therapists, involves striking the patient’s chest wall with cuffed hands. Rhythmic percussions over a targetted area are performed for 3–5 minutes as the technique is performed back and forth in a circular pattern.

Mechanical percussion involves a pneumatic or electrical device to deliver vibrations at a controllable frequency. This method is preferred because it reduces fatigue, decreases treatment time, and delivers consistent impact forces. 

Postural Drainage for Cystic Fibrosis

Postural drainage is a key component of airway clearance therapy for individuals with cystic fibrosis (CF), a genetic condition characterized by thick, sticky mucus that can clog the lungs and lead to chronic infections. This technique involves positioning the body in specific ways to use gravity to help move mucus from the smaller airways toward the larger ones, where it can be more easily coughed out or suctioned.

For cystic fibrosis patients, postural drainage is often combined with manual chest physiotherapy techniques like percussion and vibration to further loosen mucus. Different positions target different lung segments—for example, lying on your side or stomach at a downward angle can help drain the lower lobes, while sitting upright or leaning forward may target the upper lobes.

High-Frequency Chest Wall Oscillation (The Vest)

High-frequency chest wall oscillation (HFCWO), commonly referred to as “the vest,” is an advanced airway clearance therapy frequently used by individuals with cystic fibrosis and other chronic lung conditions. The device consists of an inflatable vest connected to a machine that rapidly inflates and deflates the vest, creating gentle, high-frequency vibrations across the chest wall.

These oscillations help to loosen and thin mucus in the lungs, making it easier to cough up and clear from the airways.

The vest is especially useful for patients who struggle with traditional chest physical therapy techniques or need a more convenient, at-home solution. Treatments typically last around 20–30 minutes and can be performed while the patient sits, reads, or even watches TV. Many vests are programmable and can be adjusted for frequency, pressure, and duration based on individual needs and physician recommendations.

Note: Regular use of HFCWO has been shown to improve lung function, reduce the frequency of respiratory infections, and enhance quality of life for patients with conditions that lead to excessive mucus buildup.

Procedural Guidelines and Safety Measures

Safe and effective chest physical therapy requires careful preparation, ongoing monitoring, and adherence to key safety precautions. Accurate positioning, patient observation, and awareness of risks help prevent complications.

Preparation and Positioning Protocols

Patients should be evaluated for contraindications, such as recent surgeries, active bleeding, or unstable cardiovascular conditions, before beginning postural drainage or CPT. The practitioner explains the procedure, gains informed consent, and confirms the patient’s comfort with the process.

Cushions or pillows support the patient in each drainage position, such as Trendelenburg or side-lying. These positions are adjusted based on which lung segments need drainage, the patient’s physical limitations, and their respiratory status.

Clothing should be loose, and the airway should be cleared if needed. Therapy is usually scheduled at least one hour before or two hours after meals to reduce the risk of aspiration or vomiting during the procedure.

Monitoring During Therapy

Throughout the session, close observation is critical. Practitioners regularly assess the patient’s breathing pattern, skin color, oxygen saturation, and level of comfort.

Verbal feedback from the patient is encouraged to quickly address symptoms like shortness of breath, dizziness, or pain. If vital signs such as heart rate or blood pressure change significantly, the session is stopped and medical evaluation is performed.

Equipment such as pulse oximeters may be used to monitor oxygen levels. Practitioners document the procedure, including duration and patient response, in the medical record.

Common Risks and Safety Precautions

Common risks of CPT include hypoxemia, vomiting, aspiration, bronchospasm, and injury to ribs or soft tissues. Patients with osteoporosis, rib fractures, or bleeding disorders require extra care to avoid trauma.

Frequent coughing and expectoration may cause fatigue or discomfort, so breaks are provided as needed. Practitioners use gentle, controlled force when performing percussion or vibration, especially in children or elderly patients.

Clear emergency protocols should be in place in case of respiratory distress or sudden complications. Personal protective equipment is worn, and all tools are cleaned and maintained according to infection control guidelines.

Other Types of Airway Clearance Therapy

There are several different types of airway clearance therapy, including the following:

• Chest Physical Therapy (CPT)
• Positive Expiratory Pressure (PEP) Therapy
• Autogenic Drainage
• High-Frequency Chest Wall Compression (HFCW)
• Mobilization and Physical Activity
• Active Cycle of Breathing
• Intrapulmonary Percussive Ventilation (IPV)
• Mechanical Insufflation-Exsufflation (MIE)

Note: Each type has advantages and disadvantages and requires a different technique for delivery, but the primary goal of each type is to help clear secretions from the lungs.
