Postural drainage is a technique used to help clear mucus from the lungs in individuals with respiratory conditions like cystic fibrosis, pneumonia, or chronic bronchitis. The technique involves positioning the patient in specific ways that help promote the movement of mucus from the smaller airways to larger airways where it can be more easily cleared. Postural drainage is often used in combination with chest physiotherapy, which includes techniques like percussion and vibration to loosen and mobilize mucus.

During postural drainage, the patient is positioned so that gravity helps move mucus toward the larger airways. The therapist may use tapping or cupping techniques to enhance mucus clearance. This technique is effective in improving lung function, reducing the risk of infection, and promoting better breathing in individuals with chronic lung diseases.

Postural drainage is an essential technique in respiratory therapy, helping patients with respiratory conditions clear mucus and improve lung function.
