摘要：
An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient (1) undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patients airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower (15) for providing a flow of gas to a patients airway (1) at a pressure, a sensor (11) to measure a characteristic of the flow, a controller (8) to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator (21) for adjusting the pressure based on the information.
