Abstract: Ventilator adapted to be connected to a source of gas comprising a case and an inlet adapted to be connected to the source of gas. It also is comprised of an oscillator cartridge carried by the case having a body with an inlet and an outlet and a flow passage interconnecting the inlet and the outlet. A valve member is carried by the body and is movable between open and closed positions with respect to the outlet. A diaphragm is also carried by the body and is connected to the valve member. A servo port is carried by the body for supplying gas to one side of the diaphragm to cause movement of the diaphragm to move the valve member between open and closed positions to interrupt the flow of gas from the inlet to the outlet. An adjustable impact metering valve is provided for metering the flow of gas to the servo port. A patient adapter and a pneumatic clutching device having an output coupled to the airway of the patient adapter are provided. A one-way check valve couples the adjustable impact metering valve to the outlet from the oscillator cartridge and the pneumatic clutching device. The impact metering valve in combination with said one-way check valve makes it possible to stack successive volumes of gas on the airway of the patient.

Abstract: The patient breathing monitoring apparatus is used for monitoring the airway of a patient which has a respirator connected thereto and which is connected to a source of gas. The respirator is of a type which during the inhalation phase supplies inspiratory gases to the airway of the patient and during exhalation phase permits the discharge of gases from the airway of the patient. The monitoring apparatus includes first and second pressure switches each of which has an inlet connected to the airway of the patient. One of the pressure switches is adjustable to sense a decrease in pressure in the airway below a predetermined value whereas the other of the switches is adjustable to sense an increase in pressure in the airway above a predetermined value. An alarm devices is coupled to the pressure switches for giving an alarm when the one switch senses a decrease in pressure below the predetermined value and when the other of the switches senses an increase in pressure above a predetermined value.
