When considering patient morbidity, mortality and costs, pressure sore formation is a major health care concern. An adjunct to the nursing care plan for prevention and treatment is the selection of a pressure reduction/relief device. This review of four pressure reduction device studies is intended to increase the vascular nurse's knowledge base concerning pressure reduction device efficacy. Each study is reviewed and graphed to identify like patterns within each study. Foam is judged to be least effective. Air cell and air mattress overlays are found to be intermediate devices and the low air loss beds appear to be the most effective. Few of the tested devices reduced pressure below 32mmHg at the heel site, leaving the heel at risk for breakdown.
在考虑患者的发病率、死亡率和成本时，压疮的形成是医疗保健的一个主要关注点。预防和治疗护理计划的一个辅助措施是选择减压/缓解装置。对四项减压装置研究的综述旨在增加血管护士关于减压装置功效的知识库。对每项研究进行综述并绘制图表，以识别每项研究中的相似模式。泡沫被判定为效果最差。气圈和气垫被发现是中等效果的装置，而低空气流失床似乎是最有效的。在足跟部位，很少有测试装置能将压力降低到32mmHg以下，这使得足跟有发生破损的风险。
