A method is described by which the effect of pressure and relief of pressure on blood flow in cutaneous and subcutaneous tissue can be evaluated. Five normal persons were placed supine on a transparent polyacrylate board and blood flow in the skin overlying the sacral area was measured. Cutaneous blood flow was measured by the laser-Doppler technique and subcutaneous blood flow was measured by the 133Xenon washout technique using atraumatic application. Blood flow was measured by both techniques before and after relief of pressure, using the antipressure material Comfeel Pressure Relieving Dressing (in the following referred to as Comfeel PRD) consisting of a foamy plastic material with an adjustable central opening. With this material, it was possible to obtain relief of pressure which was shown as a significant increase in blood flow measured by both methods. It is suggested that the methods described should be used to test other materials as well.
本文描述了一种评估压力及压力解除对皮肤和皮下组织血流影响的方法。五名正常人仰卧于一块透明聚丙烯酸酯板上，测量其骶部上方皮肤的血流。皮肤血流采用激光多普勒技术测量，皮下血流采用无创应用的133氙清除技术测量。在使用由带有可调节中心开口的泡沫塑料材料制成的减压材料康惠尔减压贴（以下简称康惠尔PRD）解除压力前后，用这两种技术测量血流。使用这种材料能够实现压力解除，这表现为两种方法测量的血流均显著增加。建议也应使用所述方法来测试其他材料。
