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.
摘要
对10例稳定型中重度间歇性跛行患者在最大运动期间监测经皮氧分压（TcPO2）。在出现跛行时，TcPO2下降了16%，在最大行走距离时下降了32%。运动后休息时，这种下降在大约4分钟后达到最大66%。随后是稳步恢复。每位患者的百分比变化都是可重复的，并且与正常健康志愿者的TcPO2运动曲线明显不同。运动期间监测TcPO2是一种评估间歇性跛行的简单、可重复、廉价且有用的技术，与用于量化这种情况的其他技术相比具有优势。
