Abstract
A system and method for providing a therapeutic treatment, such as a flow of breathing gas, to a patient at variable treatment levels. A respiratory cycle monitor detects the patient's respiratory cycles and a control unit incrementally adjusts the treatment level from a first predetermined level to a second predetermined level over a first predetermined number of respiratory cycles. The amount of the incremental adjustment and the frequency of such adjustments over the course of the first predetermined number of respiratory cycles can be controlled to achieve a desired change in the therapeutic treatment over the course of the patient's respiration.
