Pressure Relief 1 -
Therapeutic Surface Comparison
St. Mary's Hospital
Rochester, Minnesota

On April 3, 2001 Comfortex conducted an Interface Pressure Evaluation with staff members from St. Mary’s Hospital in Rochester, MN. The volunteer, a 115 lb. healthy female, was used to compare the pressure reducing capabilities of a low airloss bed, a low airloss mattress and Comfortex’s non-mechanical Rest-Q mattress.

Interface pressures were recorded on a computer assisted X-SENSOR pressure monitor.
