Nurses employed in acute care hospitals frequently encounter patients who require a pressure-relieving device. It is often difficult for nurses to decide which support surface should be used to best meet a patient's need for a pressure-reducing device because of the multiplicity of products available. One of the variables studied was found not to statistically influence the effectiveness of the various pressure-relieving devices. Body build is not a consideration when determining which support surface is effective in a healthy population of subjects. The two air-flotation low air-loss beds would be defined as effective pressure-relieving devices. The interface pressure readings vary from individual to individual on various bony prominences. The population studied was that of healthy volunteers. Healthy subjects have an increased fat pad in their sacral area compared with the critically ill patient. The heel had the highest interface pressure of the five that were studied. This is a bony prominence that requires additional attention if skin integrity is to be maintained.
急症医院雇佣的护士经常会遇到需要减压设备的患者。由于市场上有多种产品可供选择，护士往往很难决定使用哪种支撑面能最好地满足患者对减压设备的需求。研究发现，其中一个研究变量在统计学上并不影响各种减压设备的效果。在确定哪种支撑面对健康受试者群体有效时，体型不是一个需要考虑的因素。两张气浮低气损床可被定义为有效的减压设备。不同个体在各个骨突部位的界面压力读数各不相同。所研究的人群为健康志愿者。与重症患者相比，健康受试者的骶部有更多的脂肪垫。在所研究的五个部位中，足跟的界面压力最高。如果要保持皮肤完整性，这个骨突部位需要格外关注。
