1, 2, and 3 only. Postural drainage is a technique used to clear mucus from the lungs and is most effective in conditions that produce excessive sputum. It often involves positioning the body in ways that use gravity to assist in mucus clearance, with head-down positions greater than 25 degrees being commonly used for certain lung segments. Adequate hydration is important for the technique's effectiveness, as it helps thin the mucus, making it easier to clear. While it can improve mucociliary clearance in individuals with certain lung conditions, stating it improves clearance in normal subjects (4) is not specifically accurate in the context of the benefits of postural drainage, as normal subjects typically do not require interventions to improve mucociliary clearance.
