Transcutaneous oxygen tension (TcPo2) of the lower extremities was investigated in 20 patients of peripheral arterial occlusive disease. TcPo2 was monitored from bilateral calf and dorsum of the foot. Femoral compression method meant that the tourniquet was set at femoral region and the tourniquet was inflated to a suprasystolic pressure for 4 minutes, after cuff was deflated, TcPo2 returned to the initial level. T(min) was the time it took until initial TcPo2 level. T1/2(min) was the time it took until 50 percent of the initial level. The following results were obtained. T1/2 showed significant relation to Ankle Pressure Index. T1/2 of dorsum of foot showed blood flow of distal side of calf region and T1/2 of calf showed blood flow of femoral region. T1/2 was significant difference between ASO and TAO, among different sites of peripheral vascular occlusion. T1/2 measurement was a much more useful indicator of limb flow after operation than TcPo2 measurement.
对20例外周动脉闭塞性疾病患者的下肢经皮氧分压（TcPo2）进行了研究。从双侧小腿和足背监测TcPo2。股动脉压迫法是指将止血带置于股部区域，将止血带充气至收缩压以上并维持4分钟，松开袖带后，TcPo2恢复至初始水平。T（min）是恢复到初始TcPo2水平所需的时间。T1/2（min）是恢复到初始水平的50%所需的时间。获得了以下结果。T1/2与踝压指数呈显著相关。足背的T1/2显示小腿区域远端的血流，小腿的T1/2显示股部区域的血流。在不同部位的外周血管闭塞中，T1/2在动脉硬化闭塞症（ASO）和血栓闭塞性脉管炎（TAO）之间存在显著差异。与TcPo2测量相比，T1/2测量是术后肢体血流更有用的指标。
