Abstract
A respiratory assistance device includes a patient interface for coupling to a patient respiratory passageway, and a selectively regulated therapeutic gas flow source in pneumatic communication with the patient over the patient interface. A ramping controller is connected to the therapeutic gas flow source and is receptive to inputs of a prescription pressure level, an initial pressure level, a total ramp duration, and a numeric value corresponding to a ramping duration. Therapeutic gas flow at an initial pressure level is regulated for a ramp delay duration reciprocal to the ramping duration relative to the total ramp duration. The ramping controller incrementally increases therapeutic gas flow to the prescription pressure level from a ramp start time to a ramp end time at a delivery pressure increase rate derived from the numeric value of the ramping duration and the total ramp duration.
