Apparatus (10) comprises a pressure controller (26), a first processor (30) for providing a signal (36) proportional to instant flow rate, a second processor (38) for providing a reference signal (40), and a comparator (34) for providing a drive signal (42) for the controller (26). By this apparatus (10) alternating high and low positive airway pressure can be applied in the airway of the patient, and coordinated with the spontaneous respiration, which is useful in the treatment of sleep apnea. |
