Abstract
A ventilator apparatus comprises a pump; a delivery conduit for delivering pressurized air to a patient; a relief valve preventing the pressure in the delivery conduit from rising above a predetermined peak value; a sensor for sensing the pressure in the delivery conduit; a storage device for storing the sensed peak pressure; and a comparator for continuously comparing the sensed pressure with the stored peak pressure and effective to energize the pump whenever the sensed pressure is below the stored peak pressure, and to deenergize the pump whenever the sensed pressure is generally equal to the stored peak pressure.
