Document Type and Number:
Japanese Patent JPS60222066
Kind Code:
A
Abstract:
A ventilating system includes a high frequency controlled breathing gas source in HFJV operation, wherein the exhaled gas is removed through an outlet line through which a flush gas is conducted, is improved to permit a determination, under high frequency ventilation, of both the final expiratory CO2 concentration and the basic pressure building up in the lungs (the lung-internal PEEP). To this end, the control device is in addition connected to a flush gas valve provided upstream of the breathing gas supply device, and designed to intercalate a measuring interval after a sequence of breathing gas pulses, during which interval the breathing gas valve and the flush gas valve are closed. A system of measuring the breathing gas valves is provided in the outlet line and it is actuated during the measuring interval to perform the measuring operation.
