Postural drainage is a technique used to help clear mucus from the lungs and is particularly effective in conditions that lead to excessive sputum production. 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 among the most effective. Adequate hydration is important for the technique's effectiveness, as it helps to thin the mucus, making it easier to clear.
