Pressure ulcers/injuries are not only prevalent in the long-term care facilities but also in the acute care setting. Pressure ulcer development has many contributing factors, including prolonged high surface interface pressure between the skin and mattress surface.
The purpose of this quality improvement project was to measure the pressure redistribution properties of 4 hospital surfaces.
Pressure measurements were performed on 8 participants lying on 1) standard mattress; 2) standard mattress with a static, air-filled bed overlay placed on top of it; 3) mattress with pulsing technology; and 4) mattress with immersing technology. Participants were volunteers measured while lying in the supine position and, in one instance, in the prone position. Pressures were measured with a full-body interface pressure mapping system.
Of the 4 surfaces evaluated, the surface that provided the most effective pressure redistribution properties was the combination of the standard viscoelastic mattress with the static, air-filled overlay.
These results can help guide surface choice for providing the best pressure redistribution properties in order to help prevent pressure ulcers/injuries.
压疮/损伤不仅在长期护理机构中普遍存在，在急性护理环境中也同样如此。压疮的发展有许多促成因素，包括皮肤和床垫表面之间长时间的高表面界面压力。
本质量改进项目的目的是测量 4 种医院表面的压力再分布特性。
对 8 名参与者进行压力测量，他们分别躺在 1）标准床垫上；2）标准床垫上放置一个静态充气床罩；3）带有脉冲技术的床垫；和 4）带有浸没技术的床垫上。参与者在仰卧位和俯卧位各进行了一次测量。压力通过全身界面压力映射系统进行测量。
在所评估的 4 种表面中，提供最有效压力再分布特性的是标准粘弹床垫与静态充气覆盖物的组合。
这些结果有助于指导表面选择，以提供最佳的压力再分布特性，从而有助于预防压疮/损伤。
