The Philips Respironics CoughAssist E70 device assists patients in loosening, mobilizing, and clearing secretions by providing high frequency oscillatory vibrations while gradually applying a positive pressure to the airway, then rapidly shifting to a negative pressure. The oscillatory vibrations assist in loosening and mobilizing the secretions while the rapid shift in pressure produces a high expiratory flow rate from the lungs, which promotes the clearance of secretions.

The CoughAssist E70 device may be used either with a facemask or mouthpiece, or with an adapter to a patient’s endotracheal or tracheostomy tube. It is for use on adult or pediatric patients having difficulty with secretion clearance and/or inability to cough.

The CoughAssist E70 device is for use in a hospital, institutional environment, or in the home.
