Transcutaneous Measurement of Oxygen and Carbon Dioxide Tension (TcPO2 and TcPCO 2) during Treadmill Exercise in Patients with Arterial Occlusive Disease (AOD)—Stages I and II
Transcutaneous oxygen and carbon dioxide tensions were measured during treadmill exercise in 30 patients with stages I and II arterial occlusive disease and 28 normal controls. Measuring sites were the dorsum of the foot and the frontal thorax. The calculated oxygen index at maximum exercise/rest (foot/ thorax) differentiated with 100% sensitivity and specifity between the two groups. The oxygen index was the only parameter with a significant positive correlation with the pain-free walking distance, whereas, eg, oscillography and Doppler analysis did not correlate. Carbon dioxide tensions showed significant differences only in the recovery time between patients and normal controls.
