electric blood warmer, a device for heating blood before infusions, especially massive transfusions in which cold blood may cause a state of shock. The electric blood warmer includes a receptacle containing an electric heater and space for the insertion of a disposable blood-warming bag composed of parallel plastic tubes. The warmer is also equipped with a temperature indicator, which shows when the heating bag reaches the proper temperature of 99° F (37.6° C). An IV Y-set is commonly used in transfusions involving the electric blood warmer.
