摘要：
A low-cost CPAP apparatus in which, upon detection of the transition frominhalation to exhalation, the blower motor is de-energized to allow it tofreewheel. When the pressure in the patient mask (or whatever interface isutilized) reaches a minimum pressure level during exhalation, the motor is re-energized and its speed is controlled so to maintain the pressure at a levelsuitable for exhalation. Upon detection of the transition from exhalation toinhalation, the motor speed is increased to provide higher pressures in thepatient mask suitable for inhalation.
