Comparative Measurements of Interface Pressures Between Two Pressure-ulcer Prevention Mattresses: Softform Premier and Airsoft Duo

Comparative Measurements of Interface Pressures Between Two Pressure-ulcer Prevention Mattresses: Softform Premier and Airsoft Duo

The main objective of this study is to compare the Softform Premier mattress (in static mode) and AIRSOFT DUO mattresses in terms of skin pressures measured at the sacral area.

The secondary objectives of the study are to compare the two devices in terms of:

A. contact surface. B. heel pressure. C. On the occurrence of pressure ulcers anywhere on the body at month 1. D. patient comfort after 1 month (visual analog scale ranging from 1 to 10).
