Prospective randomised trials indicate that the low air loss bed is a successful method of treatment for pressure sores. To study the properties of these beds interface pressures were measured in two different low air loss beds. Ten healthy volunteers had eight readings at six different body sites taken supine and sitting. Occipital and heel pressures for both products exceeded 4.7 kPa, the accepted capillary closing pressure, while pressures at other sites were below this. These findings suggest that pressure relief alone is not the sole reason for the clinical acceptance of low air loss beds in the treatment of pressure sores.
前瞻性随机试验表明，低气耗床是治疗压疮的一种成功方法。为研究这些床的特性，在两种不同的低气耗床上测量了界面压力。10名健康志愿者在仰卧位和坐位时，于6个不同身体部位进行了8次读数测量。两种产品的枕部和足跟压力均超过了公认的毛细血管闭合压力4.7 kPa，而其他部位的压力则低于此值。这些发现表明，单纯的压力缓解并非低气耗床在压疮治疗中被临床接受的唯一原因。
