In the past 20 years there has been a dramatic increase in different types of support surfaces to reduce the incidence of pressure ulcers. The purpose of this study was to determine the effect of static air overlays (Sof-Care and Tendercloud), replacement mattresses (Dermarest and Therarest), and a standard hospital mattress on tissue interface pressures in healthy subjects. A convenience sample of 25 subjects had tissue interface measurements obtained under the sacrum and heel bony prominences on the five support surfaces in the supine and 45-degree Fowler's positions. A repeated measures analysis of variance (p < 0.05) indicated that the Dermarest, Therarest, Sof-Care, and Tendercloud support surfaces reduced pressure significantly under the sacral bony prominence compared with the standard hospital mattress. Heel interface pressure measurements were significantly higher than sacral interface pressure measurements. There was no significant difference between supine and 45-degree Fowler's positions with respect to tissue interface pressures.
在过去20年里，为降低压疮发生率而设计的不同类型的支撑面急剧增加。本研究的目的是确定静态空气垫（Sof-Care和Tendercloud）、替代床垫（Dermarest和Therarest）以及标准医院床垫对健康受试者组织界面压力的影响。选取25名受试者作为便利样本，在仰卧位和45度福勒氏位下，于五个支撑面上测量骶骨和足跟骨突出部位的组织界面压力。重复测量方差分析（p < 0.05）表明，与标准医院床垫相比，Dermarest、Therarest、Sof-Care和Tendercloud支撑面在骶骨突出部位显著降低了压力。足跟界面压力测量值显著高于骶骨界面压力测量值。仰卧位和45度福勒氏位在组织界面压力方面无显著差异。
