  • Process and arrangement for determining the perfusion factor of a gas in a sample
    Patent number: 4114602
    Abstract: A process and an arrangement for determining the perfusion factor of a gas in a sample, particularly of oxygen dissolved in blood flowing through biological tissue, includes measuring the amount of gas diffused from the sample by means of a polarographic cell which comprises a reference electrode having a heat conductive surface which is adapted to be placed in heat-transmitting relationship over a portion of the sample, and a sensor electrode in electrolytic contact with the reference electrode so as to generate a signal indicative of the amount of gas being diffused from the sample portion. A heating unit comprising a high frequency generator to establish a high frequency field in the sample is also provided for heating the sample diathermically to a desired temperature.
