Checking the Mattress Setting
WARNING The head of the bed should be maintained at the lowest degree of elevation consistent with medical conditions; otherwise injury may occur. The lowest skin pressure is maintained with 0° to 20° head raise angle. Angles above 30° place more body weight over the seat area, reducing pressure relief. Instruct the caregiver to avoid head angles over 30° for extended periods, unless medically necessary (U.S. Department of Health and Human Services publication No. 92-0048). 1. Before elevating the head of the bed, elevate the knee section first. NOTE: Head elevation without knee elevation may cause the patient to slide toward the foot of the bed. 2. Elevate the head of the bed to 30°- 45°. 3. Using your hand, check under the patient’s buttocks and between two air tubes to check if the patient has bottomed out. 4.
