<p>An apparatus is disclosed for monitoring the partial pressure of a gas in the liquid flowing in a line, for example the PO2 or PCO2 tension in blood. The apparatus comprises a connector (1) adapted for insertion in the line, the connector having a wall which includes a membrane (2) permeable to the said gas but impermeable to the said liquid. The membrane (2) 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 (4), is located adjacent the said second face and is responsive to gas passing through the membrane from the liquid.</p> |
