“…E.W.N.P. was found to be more eflective than the expiratory impulse bellows of Forbes (1958). This is only to be expected, as in exsuffiation with this bellows the expiratory flow rate and pressure gradient depend on the passive recoil of the rustended chest wall and lungs.…”

Summary A simple machine by which exsufflation with negative pressure (E.W.N.P.) can be performed to provide an artificial cough is described. Artificial coughing by this means allowed the control of lung complications in 20 patients with respiratory paralysis in whom retained bronchial secretions were an important problem. Massive collapse was relieved on eight occasions in seven patients. Prophylactic coughing makes possible the removal of a tracheotomy tube from patients with negligible respiratory muscle power. E.W.N.P. produces changes essentially similar to those occurring during normal human coughing and does not appear to have any harmful effect on the lungs or circulation. Besides patients with respiratory muscle weakness, artificial coughing is likely to be of greatest value in conditions in which there is prolonged unconsciousness.
