Central rewarming heat is applied to which areas?

• A. Lateral chest, neck, armpits, and groin
• B. Head and neck
• C. Back and legs
• D. Arms and hands

Answer: (A)

Central rewarming targets areas where large vessels are close to the skin so warmed blood can circulate to raise core temperature quickly. The lateral chest, neck, armpits, and groin provide access to major vessels (such as the aorta, carotids, femoral, and axillary) and thus heat can spread efficiently to the body's core. Warming regions like the head and neck alone, the back and legs, or the arms and hands is less effective for increasing core temperature rapidly because those areas are more peripheral and don’t move heat into the central circulation as quickly.
