Water Flotation for Sked Stretcher. Skedco has added a new dimension in litter flotation by developing two systems which enable the Sked Stretcher to float vertically. Vertical flotation reduces the possibility of patient drowning due to capsizing. Flotation of the Sked Stretcher is accomplished with a pair of 5″ diameter Ethafoam logs and an inflatable chest pad. The Ethafoam floats provide approximately 56 lbs. of flotation. In order to make the Sked float vertically they use a 15 lbs. ballast in a nylon bag. Two extra-long webbing handles. This flotation is simple to use. An experienced person can package a patient in water in as few as two minutes. Made in USA.
