b. Proper utilization of an air-fluidized bed

Frequent repositioning, which temporarily relieves pressure, is the backbone of preventive protocols. It is the nurse's responsibility to use appropriate turning schedules for patients in bed or on a chair. No bed or mattress totally eliminates the need for competent nursing care.
