Abstract
A method and apparatus for ventilating a patient wherein the inspiratory positive airway pressure (IPAP) is adjusted as a function of minute volume. The IPAP is gradually adjusted over extended periods of time in small increments to conform the patient's minute volume to a prescribed value. This gentle but effective approach ensures adequate ventilation while minimizing discomfort to the patient thereby rendering the system ideal for treating sleep disordered breathing in the homecare environment.
