An arrangement for measuring and controlling the partial pressure of gases, especially carbon dioxide and/or oxygen, dissolved in the blood of a patient comprises unit (1) including a first space element (2), arranged to be supplied with a gaseous medium serving as carrier gas, and a second space element (3), arranged to be connected to the arterial or venous circulation of a patient for continuous blood flow through the second space element (3). Unit (1) is also provided with a gas- permeable, membrane (4) which separates the space elements (2, 3) from each other. Space elements (2 and 3) and membrane (4) are dimensioned and selected so as to produce in the first space element (2) a sample that represents the gas contents of a patients' blood. Means (9) provides for the determination of the contents of the desired gases in space element (2). The arrangement may be connected into a blood flow line in oxygenator or hemodialysis equipment. <IMAGE> |
