Chest physiotherapy also known as CPT is the process of removing the excess secreted sputum in the respiratory system especially those contained in the lung area. This is done so as to improve the breathing process of a patient wherein the airway obstructions are cleared. In such way, the respiratory muscles are enhanced in order to receive more oxygen.

Mucus secretion is normal as long as it moistens the lungs, however as the mucus thickens the risk of chest infection may be possibly occur. Such abnormalities can prevent the expulsion of mucus and that the CPT is prescribed. The procedure is considered effective regardless of the age of the patient.

Chest physiotherapy is commonly recommended to patients with cystic fibrosis in order to eradicate the sputum present in the airways. Respiratory diseases such as bronchitis, COPD, and pneumonia also needs the CPT. Usually the procedure includes the postural drainage, controlled deep breathing exercises and the vibration of chest or the percussion. These procedures are often performed with various treatment methods such as suctioning and nebulization therapy.

One of the most important methods in CPT is the postural drainage wherein the body is being positioned that the mucus in the lungs can be drained towards the throat. After the postural drainage, it is advisable to do the assisted coughing to provide cough pressure in order to expel the mucus.

Although CPT is considered as an effective means of mucus removal, it is not recommended for people with tuberculosis, acute asthma, fractured ribs or those who have undergone recent surgery. Before CPT is applied, the overall health of the patient must be taken into consideration.
