Patent number: 6723216Abstract: A method for detection of a bubble in a liquid which is placed in a measuring chamber and is in contact with a sensor for measuring the partial pressure of a particular gas in a liquid is provided. The method includes performing a first measurement of the partial pressure of the particular gas in the liquid at a first pressure in the measuring chamber. Next, the pressure in the measuring chamber is changed to a second pressure. A second measurement of the partial pressure of the gas in the liquid at the second pressure in the measuring chamber is performed. An expected result of the second measurement based on the first measurement and assuming that no bubbles are present in the measuring chamber during any of the measurements is provided. The actual result of the second measurement is compared with the expected result and a conclusion is drawn on the presence of a gas bubble in the liquid based on the comparison. An apparatus for measuring the content of a particular gas in a liquid is also provided.Type: GrantFiled: April 29, 2002Date of Patent: April 20, 2004Assignee: Radiometer Medical A/SInventors: Michael Taagaard, Allan Larsen
