Central rewarming targets which areas for heat application?

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

Answer: (D)

Central rewarming aims to raise core temperature quickly by warming blood as it circulates near the body's center. The most effective places to apply heat are areas where large vessels run close to the skin, so the warming heat enters the central circulation rapidly. These zones include the neck (carotid area), the chest, the armpits (axillary region), and the groin (femoral region). Targeting these regions helps warm blood en route to the core, which speeds up warming of the brain, heart, and other vital organs.

Warming the arms and hands or focusing heat on the abdomen and back alone is less efficient for raising core temperature because they’re further from the central circulation and involve more peripheral tissue. The combination of the lateral chest, neck, armpits, and groin covers the key central areas near major vessels, making it the best choice for central rewarming.
