Abstract

A method and device for sensing inhalations and controlling the delivery of oxygen or other therapeutic gases to a patient. A flow-through sensor is adapted to provide a method and device to monitor various parameters of a patient's breathing and/or pulse oxygen saturation. Adjustments are made to the bolus delivery from a source of therapeutic gas to efficiently provide appropriate levels of therapeutic gas to the patient and to economically conserve therapeutic gas.
