Abstract
The development of a reliable, inexpensive, inhalation sensor which is actuated by the inhalation flow of air obtained from a cannula worn by the patient is described. With no electrical connection to or near the patient, an electrical output, resulting from electrooptical sensing of a very-low-mass moving sphere, can be used for apnea monitoring or for triggering a dose of gas for inhalation therapy.
