The effect of externally applied load on skin blood flow was examined over the ischial tuberosity by using skin surface oxygen measurements, photoelectric plethysmography, and thermal clearance measurements. The load applied to each transducer in turn was increased every 10 minutes until blood flow was occluded. Cut-off pressures of 40 to 48kPa (300 to 360 mmHg) were recorded. Differences between the average pressure over the entire indenter and pressures at its center were investigated. A combined pressure and PO2 measuring device is presented.
通过使用皮肤表面氧测量、光电体积描记法和热清除测量，研究了施加于坐骨结节的外部负荷对皮肤血流的影响。依次施加于每个换能器的负荷每10分钟增加一次，直至血流被阻断。记录到的截止压力为40至48kPa（300至360mmHg）。研究了整个压头的平均压力与其中心压力之间的差异。介绍了一种压力和PO₂联合测量装置。
