Abstract
Apparatus for the sup-ply of breathable gas cycli-cally at an inspiratory pres-sure and the lower expira-tory pressure substantially in synchronism with a patient's (16) respiration is disclosed.
A flow generator (10) is cou-pled to a gas delivery system (12) to deliver the breath-able gas to the patient's air-ways. A motor controller (23) receives a signal (36) representing respiratory flow.
A motor controller (23) out-puts a control signal (24) has control over the electric mo-tor (25) and thus the tur-bine (22) to generate the re-quired inspiratory and expi-ratory pressures. The con-troller (23) detects transitions between inspiration and ex-piration from the flow sig-nal (36) to discriminate be-tween patient inspiration and expiration. A counter (58) counts a first time duration commenced from the last transition to inspiration, whereby if the first time duration elapses before a transition to expiration, the con-troller (23) causes the supply of the expiration pressure. Furthermore, another counter (62) counts a second time duration commenced from the last transition to inspiration that forces the turbine (22) to supply the inspiratory pressure until the second time duration elapses even if during the second time duration there is a transition to expiration by the patient.
