National Physical Therapy Examination (NPTE) Practice Exam

The primary focus of a postural drainage technique is to facilitate drainage of pulmonary secretions. Postural drainage is a therapeutic approach used primarily in respiratory care. It involves positioning the patient in specific ways that leverage gravity to help clear mucus and other secretions from the airways and lungs.

By placing the patient in different postures, such as lying on their side or in a head-down position, the technique promotes the movement of secretions from the distal portions of the lungs toward the larger airways where they can be coughed out more easily. This is particularly beneficial for individuals with conditions that lead to mucus accumulation, such as cystic fibrosis, bronchiectasis, or after certain surgical procedures.

While strengthening respiratory muscles, improving oxygenation levels, and enhancing lung compliance are important aspects of respiratory health, they are not the primary goal of postural drainage. The technique specifically targets the mobilization and clearance of secretions to improve overall respiratory function and prevent complications related to mucus obstructions.
