(57) Abstract : A low-cost CPAP apparatus in which, upon detection of the transition from inhalation to exhalation, the blower motor is de energized to allow it to fi : eewheel. 16 When the pressure in the patient mask (or whatever interface is utilized) reaches a minimum pressure level during exhalation, the motor is re-energized and its speed is controlled so to maintain the pressure at a level suitable for exhalation. Upon detection of the transition from exhalation to ) inhalation, the motor speed is increased to provide higher pressures in the patient mask suitable for inhalation.
