title: Transcutaneous oxygen tension during exercise in patients with claudication.
abstract: Transcutaneous oxygen tension (TcPO2) was monitored during maximal exercise in 10 patients with stable moderate to severe claudication. The TcPO2 fell by 16% at the onset of claudication and 32% at the maximum walking distance. On resting this decrease reached a maximum of 66% roughly four minutes after exercise. This was followed by a steady recovery. The percentage changes were reproducible in each patient and were appreciably different from the TcPO2 exercise profiles of normal healthy volunteers. TcPO2 monitoring during exercise is a simple, reproducible, cheap, and useful technique for assessing claudication and compares favourably with other techniques used to quantify this condition.
