An inhalation sensor which uses a non-metallic diaphragm that is metallized on one side, pre-stressed, and used as one plate of a variable capacitance pressure tranducer to sense the inhalation and exhalation of air from the nostrils and/or mouth of a patient. The inhalation sensor is used for inhalation therapy by triggering a prescribed dose of therapeutic gas when inhalation takes place. The inhalation sensor can also be used as a monitor to detect apnea (the absence of breathing).
