ABSTRACT:
The lung ventilator safety valve circuit includes a normally open, pulse width modulated solenoid safety valve connected to a patient airway of a ventilator system. A pressure sensor monitors pressure in the patient airway, and a control unit maintains the safety valve closed when the pressure is not excessive. The safety valve is opened when the sensed pressure equals or exceeds a maximum airway pressure threshold that can be set by an operator, or in the event of a power failure.
