ABSTRACT:
A control and actuating circuit includes a switch operated by each breath delivered by a ventilator to a patient connected to the ventilator. The circuit is connected to an alarm, maintains the alarm inoperable, and places the alarm in operable condition upon operation of the switch due to the first breath delivered to the patient. The alarm is thence capable of operation if breaths additional to the first breath fail to occur.
