摘要：

A prior art demand valve has been modified to make it more responsive to persons with impaired oxygen delivery by replacing its sensing diaphragm and associated mechanically actuated valve actuator with a solenoid activated proportional control valve (56) coupled to an analog pressure transducer via a pulse width modulated current driver circuit. The pressure transducer responds to detected pressure changes in a patient's breathing tube.
