Forced air-warming devices that blow heated air onto the upper or lower body surface are commonly used to keep patients warm and maintain normothermia.These units are effective in maintaining body temperature even during a long abdominal procedure and can be used later in the postanesthesia care unit (PACU).Forced air-warming devices must be used according to manufacturers' instructions.They must be used with appropriate disposable blanket and should not have the hose inserted under surgical drapes to warm the patient (this directs the heat on the patient,with the risk of a burn,rather than filtering it through the blanket).
