&NA;对6种不同支撑表面进行多模态评价，测量健康受试者压疮易发区域的界面压力、经皮氧分压和血流量。使用柔性力敏电阻器阵列测量界面压力。采用压力传感器（力敏电阻）阵列测量了10名健康男性志愿者在仰卧位和侧卧位时的界面压力分布。将经皮氧（TcPO2）和激光多普勒流量计探头置于骶骨、右转子和右坐骨上。受试者在仰卧位和侧卧位各记录15分钟的数据。不同表面之间的血流量和压力测量值存在统计学显著差异（p < 0.05），尤其是在转子上的侧卧位和骶骨上仰卧位的TcPO 2测量值。我们的结论是，测量界面压力，经皮氧分压，和血流量允许一个更彻底的评估的生理效应的特殊支持表面比任何单一的技术。未来对患者的研究将评估使用这些测量技术的算法，以预测各种支持表面在最大限度地减少压疮方面的疗效。（Plast。重建102：2381，1998）。
&NA; Multimodality evaluation of six different support surfaces was performed measuring interface pressure, transcutaneous oxygen tension, and blood flow in pressure ulcer‐prone areas on healthy subjects. Interface pressure was measured with a flexible force‐sensing resistor array. The interface pressure distribution patterns of 10 healthy male volunteers were measured in the supine and lateral positions using a pressure sensor (force sensing resistor) array. Transcutaneous oxygen (TcPO2) and laser Doppler flowmeter probes were placed over the sacrum, the right trochanter, and the right ischium. Data were recorded for 15 minutes each with the subject in the supine and lateral decubitus positions. Statistically significant differences (p < 0.05) between the various surfaces could be observed for blood flow and pressure measurements, especially in the lateral position over the trochanter and for the TcPO2 measurements in the supine position over the sacrum. We conclude that measuring interface pressure, transcutaneous oxygen tension, and blood flow allows a more thorough evaluation of the physiologic effects of special support surfaces than any single technique. Future studies on patients will assess algorithms for using these measurement techniques to predict the efficacy of various support surfaces in minimizing pressure ulceration. (Plast. Reconstr.
