Digital systolic pressure measurements were made on 140 big toes using a photoplethysmographic technique before and after extrinsic heating of the foot. Most patients with apparent, critically ischemic feet demonstrated vasomotor activity, suggesting that much of the microcirculation of the foot was in fact intact. Significantly, nine of 21 feet which would have fallen into a critically ischemic category were recategorized after heating into a less severe group. These data confirm the value of toe pressure measurements in the assessment of severe ischemia but show that adequate foot vasodilation is essential to allow accurate conclusions to be drawn and to allow meaningful interpretation of results.
使用光电容积描记技术在足部进行外部加热前后，对140个大脚趾进行了数字收缩压测量。大多数明显患有严重缺血性足部的患者表现出血管运动活性，这表明足部的大部分微循环实际上是完整的。值得注意的是，21只原本会被归类为严重缺血的足部中，有9只在加热后被重新归类为病情较轻的一组。这些数据证实了趾压测量在评估严重缺血中的价值，但表明足部充分的血管舒张对于得出准确结论和对结果进行有意义的解释至关重要。
