1. A bi-level positive airway pressure device comprising:
a housing having a patient port for connecting to an airway of a patient;
means for generating a positive airway pressure directed through a conduit towards the patient port; and
an exhalation detector comprising a nozzle emitting a jet of a gas directed across the conduit, the jet of the gas is directed at a receptor channel when exhalation gases flow from the patient port, thereby an increase a gas pressure is present at the receptor channel when the exhalation gases flow from the patient port, and the exhalation detector having means to convert the increase in the gas pressure into a movement of an occluding member such that when the exhalation gases flow from the patient port, the occluding member moves to block the means for generating the positive airway pressure.
