When measuring transcutaneous oxygen pressure at an electrode core temperature of 37 degrees C autoregulating mechanisms of skin microcirculation can be studied. Because of poor reproducibility of a single PO2 measurement we determined skin surface oxygen pressure fields out of 50 or more PO2 values. At the forefeet and calves of healthy volunteers the histograms were slightly left-shifted with median PO2 of 4 mm Hg. Patients with multilevel arterial occlusive disease and low systolic ankle pressure presented with a disturbed PO2 distribution with very low PO2 values close to zero. About 16% of measurements were above 10 mm Hg. In contrast, diabetics had significantly higher PO2 (median 8 mm Hg) at the forefoot level when compared with healthy volunteers or patients without diabetes.
在电极核心温度为37摄氏度时测量经皮氧分压，可以研究皮肤微循环的自动调节机制。由于单次PO₂测量的重复性较差，我们从50个或更多的PO₂值中确定皮肤表面氧压场。在健康志愿者的前足和小腿处，直方图略有左移，PO₂中位数为4毫米汞柱。患有多级动脉闭塞性疾病且收缩期踝压较低的患者，其PO₂分布紊乱，非常低的PO₂值接近零。约16%的测量值高于10毫米汞柱。相比之下，与健康志愿者或无糖尿病患者相比，糖尿病患者在前足水平的PO₂显著更高（中位数为8毫米汞柱）。
