Abstract
A respiratory system and method comprise a tracker module adaptable to be secured to a variety of inhalers, the tracker module sensing activation of the medication canister of the inhaler for delivery of medication to a user. The tracker module also senses the rate of inhalation air flow of the user when inhaling medication for determination of proper inhaler use. Upstream and downstream sensors provide flow information to determine quality of the inhalation. A flow sensor is an integral part of the tracking module and can be used on multiple inhalers. Other sensors are provided that monitor user presence at the inhaler, user technique in using the inhaler, and the attitude of the inhaler when it was used. Low power devices are used to conserve battery power. A spirometer provides user lung function data.
