NATO Litter: Fluid Immersion System (FIS) Versus Traditional Mattress for Pressure Dispersion

Summary

The purpose of this study is to measure peak skin interface pressures and the total area of the body exposed to skin interface pressure above 30 mm Hg at different areas of the body in the supine position on two different support surfaces applied to a standard North Atlantic Treaty Organization (NATO) litter (NSN: 6530-01-380-7309) and a Raven 90C Litter (NSN6530-01-432-5114). The support surfaces are the Warrior Evacuation Litter Pad (WELP) and the Dolphin Fluid Immersion Simulation Stretcher System (FIS). These pressure measurements and transcutaneous oxygenation readings will allow us to determine differences between support surfaces.

Conditions

• Pressure Distribution
• Military Litters
• Peak Pressure Index
• Total Surface Area
• Tissue Perfusion

Interventions

OTHER

NATO WELP combination

Interface pressure will be measured using the XSensor X3 Pressure Mapping System. Transducers will be placed near both scapula. Measures will be obtained in upright (baseline) and supine positions on 4 randomly assigned litter mattress combinations. Constant TCPO2 measures, as well as peak pressures and total body surface area exposed to skin will be measured for the occiput, sacrum, both scapula, buttocks and heel areas. It will take about 20 minutes for each combination. The session is complete after all measures have been obtain for all litter/mattress combinations.
