A new low-cost anti-decubitus mattress for home care a comparison with other mattresses

Introduction. The aim of the study was to compare a new anti-decubitus mattress with other low-cost mattresses. Methods. Interface pressure measurements were made in supine and in sitting position. Results. The new mattress has significant lower interface pressures than other low-cost mattresses in both positions, and that there is no significant difference with an expensive anti-decubitus bed like the air-fluidized type. Measurements of shear between body and cover show that the shear is far below 10 kPa. This limit is known as a limit above which shear may play an important role in the causation of decubitus ulcers. Conclusion. The goals of the research have been achieved: the development of a low-cost anti-decubitus mattress with, in supine position, interface pressures comparable to the well-known and expensive beds; in sitting position interface pressures are also below the capillary pressure of 4.2 kPa.
