ABSTRACT:
Normal breathing cycles of a ventilator cause an alarm controller circuit to emit a periodic pulse which resets a timer circuit thereby maintaining an alarm device in an "off" condition. Patient disconnect is sensed by an alarm trigger circuit which sends an inhibit pulse to the controller circuit inhibiting the timer circuit reset pulse. This causes the timer to "time out" thereby turning on an alarm actuator circuit which causes an audible and/or visual alarm condition.
