Abstract: Objective To evaluate the decompression performance of anti pressure ulcer cushions with different materials and structures. Methods The common cotton cushion, sponge cushion, 3D fabric cushion, and upper 3D fabric and lower sponge cushion were analyzed by XSensor pressure sensor testing system. The pressure distribution, the pressure peak and the average pressure were analyzed to compare the decompression performance and the comfortable capability. Results and Conclusion The upper 3D fabric and lower sponge cushion can ensure the decompression performance with excellent permeability. Both decompression and air comfort permeability should be the future direction of ulcer cushions research and production.

Key words: anti pressure ulcer cushion, pressure distribution, pressure reduction
