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.

1. A patient treatment system comprising: gas flow generating means for providing a flow of breathing gas to an airway of a patient; pressure controlling means, associated with the gas flow generating means, for controlling a pressure of breathing gas provided to an airway of such a patient; sensing means for detecting an instantaneous flow rate V and an instantaneous volume V of the flow of breathing gas provided to such a patient; and processing means, associated with the sensing means and the pressure controlling means, for controlling the pressure controlling means such that the flow of breathing gas is provided to such a patient at a pressure in accordance with the following relation: Ppatient=R1(t){[R2(t)*(% Set)]*[((R3(t)*(FA)(V))+(R4(t)*(VA)(V))]+R5(t)*EPAP},
