Transcutaneous oxygen tension (tcPO<sub>2</sub>) was measured at the foot and chest wall in 12 normal subjects and 62 patients with arteriosclerosis obliterans (ASO). The results showed that the resting tcPO<sub>2</sub> at the foot and the chest wall was significantly lower in asymptomatic patients (p < 0.01 at the foot and p < 0.01 at the chest wall) and patients with mild and moderate intermittent claudication (p < 0.01 and p < 0.01, respectively) than in normal subjects. The postischemic response test (T<sub>½</sub>) was significantly delayed in asymptomatic patients (p < 0.05) and patients with mild and moderate intermittent claudication (p < 0.01 respectively) as compared with normal subjects.The preliminary results of this study suggest that the measurement of resting tcPO<sub>2</sub> is useful in the diagnosis of patients with mild and moderate ASO. Measurement of resting tcPO<sub>2</sub> coupled to the T<sub>½</sub> test is more useful for discrimination in the severity of the disease and may provide information concerning prognosis of the patients.
