What does a Blood Warmer do?

• A. Used to warm blood or other fluids, minimizing the risk of hypothermia
• B. Measures blood glucose levels
• C. Records patient data digitally
• D. Delivers antibiotics automatically

Answer: (A)

A blood warmer is used to raise the temperature of blood or IV fluids to near body temperature before they enter the patient. This helps prevent hypothermia, which can occur during rapid transfusions or when large volumes of cold blood or fluids are infused. Keeping the infused products warm reduces the risk of complications such as impaired clotting, cardiac stress, and arrhythmias, and is especially important in settings like surgery, trauma, or neonatal care. The device works by circulating the blood or fluid through a heated circuit and monitoring temperature to avoid overheating, with safety features in place. It is not used for measuring glucose, recording patient data, or delivering antibiotics.
