Can the Flow Dependency of the Polarographic PO2 Electrode be Used to Measure Arterial PO2 and Local Capillary Flow Transcutaneously?
The parameters which determine the skin surface pO2 (sspO2) are given by parameters which determine the oxygen supply of the tissue as well as describe the influence of the pO2 measurement. During steady state conditions oxygen delivery to the tissue is equal to its oxygen consumption, i.e. the difference between arterial and venous oxygen concentration (Ca O2-Cv O2) times blood flow, BF is equal to tissue oxygen consumption, Mo2.
