Chest Physiotherapy: When and How It’s Used

Home

Our Values

Chest physical therapy (CPT) is a specialty treatment that supports lung function, enhances breathing, and helps clear the airways. Often used for individuals with respiratory issues, CPT is essential for people with chronic lung conditions, post-surgery recovery needs, or those who have difficulty clearing mucus from their lungs.

In this article, we’ll cover the basics of CPT, when it’s typically used, and how it works.

Understanding Chest Physiotherapy

Chest physiotherapy includes several techniques designed to mobilize and remove secretions from the lungs, helping patients breathe more easily. These techniques can involve physical movements, devices, and sometimes breathing exercises.

Many patients use CPT on a regular basis to manage their lung health and enhance their quality of life.

When Is Chest Physiotherapy Used?

Chest physiotherapy is generally used for conditions where lung congestion and mucus buildup occur. Here are some situations in which CPT can be particularly helpful:

1. Chronic Respiratory Conditions

CPT is widely recommended for people with chronic conditions like cystic fibrosis, chronic obstructive pulmonary disease (COPD), and bronchiectasis.

Regular chest physiotherapy can help loosen and expel these secretions, reducing the risk of lung infections and improving overall lung function.

2. Post-Surgical Recovery

Patients may find it difficult to adequately clear their lungs following surgery, especially if they had abdominal or chest surgery. CPT can help prevent post-operative complications like pneumonia.

In these cases, physiotherapists often work with patients on specific breathing exercises and chest clapping techniques to keep the airways clear and promote healing.

3. Acute Respiratory Infections

Chest physiotherapy may also be used temporarily for acute respiratory infections, like pneumonia or bronchitis, where excess mucus can clog the airways.

In these cases, CPT helps break down and mobilize mucus, making it easier for patients to cough it out and breathe more comfortably.

How Is Chest Physiotherapy Performed?

Chest physiotherapy uses a range of techniques that work together to clear the lungs. Here are some of the common methods used in CPT:

1. Percussion and Vibration

Percussion, or chest clapping, is a technique where a physiotherapist or trained caregiver rhythmically taps on the chest with cupped hands. This gentle tapping helps to loosen mucus in the lungs, making it easier to expel. Vibration involves applying a fine, controlled shaking motion to the chest area, further loosening mucus.

These techniques are usually performed over the back and sides of the chest and can be done manually or with devices designed for CPT.

2. Postural Drainage

Postural drainage involves positioning the patient in a way that allows gravity to help drain mucus from the lungs. Patients may lie down with their head lower than their chest, or they might assume other specific positions based on the areas of the lungs that need draining. To increase its efficacy, this method is frequently coupled with vibration and percussion.

3. Breathing Exercises and Cough Assistance

Breathing exercises, such as deep breathing and controlled coughing, are also part of chest physiotherapy. These exercises help expand the lungs, promote airflow, and encourage mucus clearance.

In cases where patients have difficulty coughing effectively, caregivers or therapists may assist with techniques that make coughing easier, like huffing or the use of devices that provide positive pressure to aid in breathing.

Benefits of Chest Physiotherapy

Improved Lung Function: By clearing mucus from the lungs, CPT helps improve oxygenation and lung function.

Reduced Infection Risk: Regular chest physiotherapy can reduce the chance of lung infections, particularly in people with chronic conditions.

Enhanced Quality of Life: For many patients, improved breathing means less fatigue and a greater ability to engage in daily activities.

Post-Surgery Support: CPT helps speed up recovery and prevent complications for surgical patients, especially those who have undergone chest or abdominal surgery.

The Bottom Line

Whether or not CPT is appropriate for a person depends on their specific respiratory needs and medical condition. Healthcare providers, particularly pulmonologists and physiotherapists, can evaluate individual cases to recommend if and how CPT should be integrated into a treatment plan.

In some cases, patients can be taught basic CPT techniques to perform at home, while others may require professional assistance in a clinical setting.
