Abstract
An inhalation sensor using a thin film pre-stressed diaphragm, senses by optoelectronic means 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).
