“BAG SQUEEZING“: A PHYSIOTHERAPEUTIC TECHNIQUE

Abstract

This paper describes a means of evacuating secretions from the bronchioles and alveoli in the uncooperative patient. This is done by hyperinflation of the lungs, followed by synchronized vibratory expiration to simulate a cough reflex, and finally by removal of the secretions. Hyperinflation is achieved by manual compression of a four-litre or five-litre bag. At the plateau of hyperinflation, the pressure in the bag is suddenly released and at this moment the physiotherapist carries out expiratory vibration. This is repeated in consecutive fashion over all pulmonary regions. We believe this method is valuable in treating severely ill, uncooperative patients in whom the natural processes involved in the clearance of pulmonary secretions are inadequate.
