What is the primary goal of using postural drainage techniques?

The primary goal of using postural drainage techniques is to facilitate mucus clearance. This method involves positioning the patient in specific ways that use gravity to aid in draining mucus from the lungs and bronchi. By promoting drainage, these techniques help to clear secretions that can cause obstruction, improve airway patency, and assist in overall respiratory function.

Effective mucus clearance is particularly important for patients with conditions such as cystic fibrosis, chronic obstructive pulmonary disease (COPD), and bronchiectasis, where mucus accumulation can significantly impair breathing and lead to infections. Elevating certain parts of the body allows mucus to move towards the larger airways, where it can be more easily coughed out. Thus, the primary objective of postural drainage is not just about relieving symptoms but also enhancing lung performance by ensuring that the airways remain clear of excess secretions.
