[Transcutaneous and intracutaneous pO2 measurements in the assessment of peripheral arterial occlusive diseases]. 1987

U Reuter, and P Setlak, and C Petrow, and E Altmann, and V Sinz

The purpose of the study was to compare the results of intra- and transcutaneous pO2-measurements of patients suffering from an arterial occlusive disease of the lower extremities (Fontaine I-IV) with that of 20 healthy volunteers. The measurements were performed by one transcutaneous and two intracutaneous pO2-electrodes on the dorsum of the foot. As reference we used the ratio pf/pft of the venous occlusion plethysmography of the calf. Already at rest the transcutaneous pO2 allows a significant separation of healthy persons and patients of Fontaine II. After a 3-minute ischemic period the greatly changed time parameters 'delay-time', 'half-time of the pO2 increase' as well as the 'pO2 recovery time' permit a significant separation of Fontaine III from healthy persons and Fontaine II. The findings show that both methods complete one another. The value of a local pO2 measurement for an individual therapy control is emphasized.

D001785	Blood Gas Monitoring, Transcutaneous	The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.
