An apparatus for controlling the administration of CPAP is disclosed, where a turbine (34) provides pressurised air to the entrance of a patient's airways via a tube (32) connected with a mask (30). A servo controller (40) controls a motor (38) and thus the pressure delivered by the turbine (34) in response to a control signal from a microcontroller (62). The microcontroller (62) determines whether an apnea is occurring, and if so, then determines whether the patient's airway is patent, and if not, causes an increase in treatment pressure. If an apnea is not occurring, then the microcontroller (62) determines the presence and magnitude of partial obstruction. If there is partial obstruction, the treatment pressure is caused to increase, and if no partial obstruction, to be reduced. <IMAGE> |
