  • Patent number: 4121581
    Abstract: A ventilator monitoring system wherein the ventilator is in simultaneous fluid communication with a patient circuit and an exhaust circuit. The patient circuit comprises an inspiratory branch and an expiratory branch. A first one-way valve in the patient circuit inspiratory branch permits ingress only of a gas to the patient circuit. A second one-way valve in the patient circuit expiration branch permits egress only of patient exhaust gas to an expiration valve in the exhaust circuit. A monitor in the patient circuit expiration branch, monitors only the gas actually expired by the patient and not a combination of patient expired gas and excess gas from the ventilator.
