Abstract
A continuous positive airway pressure (CPAP) apparatus for treatment of sleep apnea stores data indicating patient compliance with the prescribed mode of use. The apparatus includes a tubular probe positioned transversely in the conduit between the blower and nose mask. The probe tip is configured for creating a varying pressure across in the probe in response to varying air flow thereacross indicative of patient respiration. A pressure sensor connected to the probe produces signals representative of the varying air pressure. Compliance data, derived from the pressure sensor signals and representative of the patient's use of the apparatus, are stored for subsequent analysis.
