| Primary | Pressure Redistribution: Peak Pressure Index | Determine the difference in the pressure redistribution qualities between the WELP and the Dolphin FIS when used as mattress on the NATO litter and Raven litter. Pressure redistribution qualities will be measured in mmHg using XSensor X3 pressure mapping technology. To minimize the risk of a faulty sensor or false reading over one sensor, the average of eight cells around the region will be recorded and referred to as the Peak Pressure Index (PPI). Peak interface pressure is the highest average pressure (mm Hg) measured over vulnerable bony prominences (occiput, sacrum, and bilateral scapula, buttocks, and heels) at 0 minutes. PPI will be measured in mm Hg and the mean will be reported | | Posted | | Mean | Standard Deviation | mm Hg | | 0 minutes | | | | ID | Title | Description |

| OG000 | North Atlantic Treaty Organization (NATO) and Warrior Evacuati | Subjects will be their own control and have repeated measurements to compare baseline and supine transcutaneous oxygenation levels, laser Doppler pressure units, and interface pressures on NATO / Raven litters and WELP / FIS mattress combinations. Interface pressure will be measured using the XSensor X3 Pressure Mapping System. Transducers and probes 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 and Doppler 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 |
