Abstract
A thermal blanket for flowing temperature controlled air upon a patient wherein the blanket is inflated with air and orifices within the blanket permit the air to flow upon the patient. The improvement includes the locating of the air inlet at a central blanket location in the patient's chest region to permit the highest air temperature to be available over the chest region, and the air flow direction produces optimum distribution. The locating of the air hose upon the blanket upper side permits the inflated blanket to insulate the hose from the patient, the portion of the blanket placed over the patient's head is perforated to facilitate forming a head receiving opening, and a transparent barrier may be affixed to the blanket upper side to cover the patient's face during respiration.
