Abstract
A system and method for providing a pressure support therapy administered to a patient, where at least one parameter associated with the pressure support therapy is varied according to a time-base parameter variation function. More specifically, at least one parameter or at least one group of parameters associated with a pressure control relation for providing a proportional assist ventilation (PAV) or a proportional positive airway pressure (PPAP) mode of ventilation is varied according to a time-based parameter variation function to control the PAV or PPAP ventilation with a maximum degree of flexibility.
