Warming units designed for in-line heating of banked blood, blood products, and intravenous (IV) solutions from about 4 degrees Celsius to near body temperature (e.g., 35 to 37 degrees Celsius) before infusion. These units usually include a disposable bag or coil of tubing and a heat exchanger (e.g., dry heat, radio-frequency, circulating fluid, water bath); some units include temperature controls and/or alarms. Usually, the blood or solution is warmed as it passes through the bag or tubing that is exposed to the heat exchanger. Blood/solution warming units are typically mounted on an IV pole between the infusion bag and the patient's venous line; they are used to minimize adverse thermal reactions in the patient. Some units are also used to heat irrigation solutions for use in arthroscopy, laparoscopy, and other procedures.
