ABSTRACT:
An apparatus is disclosed for monitoring the partial pressure of a gas in the liquid flowing in a line, for example the PO.sub.2 or PCO.sub.2 tension in blood. The apparatus comprises a connector adapted for insertion in the line, the connector having a wall which includes a membrane permeable to the gas but impermeable to the liquid. The membrane has a first face in contact with the liquid in the connector and a second face oppositely disposed to the first face. A sensor, for example, an electrochemical sensor, is located adjacent the second face and is responsive to gas passing through the membrane from the liquid.
