Various methods have been used in an attempt to decrease prolonged pressure on skin, especially over bony prominences, and thus prevent pressure sores in immobilized patients: turning frames, circle beds, flotation beds, and special mattresses. Bridging is one means of relieving pressure on bony prominences which is both simple and inexpensive. Through the proper positioning of pillows, a patient is supported above the surface of the bed with free space between the bony prominences and the bed surface. Several different positions for pressure relief are possible. Advantages of the technic include its low cost, patient acceptance, lack of mechanical components which can fail, and ease of training personnel or family members to carry it out.
人们尝试了各种方法来减少皮肤尤其是骨隆突处的长期压力，从而预防固定患者发生压疮：翻身架、圆形床、气垫床和特殊床垫。架桥是一种减轻骨隆突处压力的方法，既简单又便宜。通过正确放置枕头，患者被支撑在床面上方，骨隆突与床面之间留有自由空间。有几种不同的减压姿势可供选择。该技术的优点包括成本低、患者易于接受、没有可能出现故障的机械部件，以及易于培训工作人员或家庭成员来实施。
