The warming system consists of a high-flow convective warmer with hose-end temperature control, a convective warming blanket and accessories. The convective warmer draws ambient-temperature air through a HEPA air filter and is warmed to a selected temperature. The warmed air enters the Snuggle Warm patient blanket and is distributed through delivery channels. The warmer is quiet with a sound level less than 42dBA. It provides simple push-button operation to maintain patient normothermia. It provides precise temperature management within +/- 1 degree, with over and under temperature alerts at each of the three set points.
