How often should postural drainage be performed for optimal results?

Postural drainage is a therapeutic technique used to help clear mucus from the lungs by using gravity to drain secretions from different parts of the lung through specific body positions. For optimal results, it is typically recommended to perform postural drainage 2-4 times a day. This frequency allows for effective mucus clearance while avoiding fatigue and discomfort that may occur if it is performed too frequently, such as 5-7 times a day. Additionally, performing it less than twice daily may not effectively manage the condition requiring chest physiotherapy, as it wouldn't provide adequate opportunity for secretion mobilization.

The choice of 2-4 times a day strikes a balance, promoting effective respiratory care without overwhelming the patient. It is also important to consider the patient's specific medical condition and overall tolerance to ensure that the routine is both beneficial and manageable.
