    SSIST NTENDED 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.
  • Page 11: Use

    SSIST TENDED The Philips Respironics CoughAssist T70 is intended for use on adult or pediatric patients unable to cough or clear secretions effectively. It may be used either with facemask or mouthpiece, or with an adapter to a patient’s endotracheal or tracheostomy tube. The device is intended to be used in the hospital, institutional environment, or in the home.
