This paper describes the effect of applied pressure on soft tissue and its possible role in the development of pressure ulcers. It concentrates on the quantification of the applied pressure at the patient-support interface and the limitations and variability of current techniques, measurement systems and data presentation. It then describes the effects of interface pressures at the tissue and cellular level, and attempts that have been made to describe and model the tissue mechanics. Finally it sets a challenge to medical engineers to improve the present measurement systems and tissue models, thus increasing understanding, both clinically and at the cellular level, so that the incidence of pressure ulcers can be reduced.
本文描述了施加压力对软组织的影响及其在压疮形成过程中可能发挥的作用。它着重于对患者支撑界面处施加压力的量化，以及当前技术、测量系统和数据呈现方式的局限性与变异性。接着描述了界面压力在组织和细胞层面的影响，以及为描述和模拟组织力学所做的尝试。最后，它向医学工程师提出挑战，要求他们改进当前的测量系统和组织模型，从而在临床和细胞层面增进理解，以便降低压疮的发生率。
