A novel respiratory method and apparatus permits ventilatory therapy in patients requiring respiratory assistance by establishing a substantially continuous positive airway pressure to enhance functional residual capacity, and a periodic release of the substantially continuous positive airway pressure reduces airway pressure at intervals to permit passive reduction in lung volume below functional residual capacity to thereby enhance alveolar ventilation and carbon dioxide excretion.

A method of providing ventilatory assistance to patients afflicted with impaired spontaneous respiration capability comprising the steps of: providing a continuous supply of breathing gas to the airway of such a patient; coincident with said providing step, maintaining the airway pressure of such a patient substantially constantly at an elevated base pressure level above ambient atmosphere pressure in a manner to permit substantially continuous spontaneous respiration while the patient\s airway pressure is maintained at said elevated base pressure; intermittently reducing the airway pressure of such a patient from said elevated base pressure level to a threshold pressure level not substantially less than ambient atmospheric pressure; maintaining the airway pressure of such a patient substantially at said threshold pressure level for a time period of predetermined duration; and returning the airway pressure of such patient to said elevated base pressure level.
