Which core temperature value defines hypothermia in EMS terms?

Which core temperature value defines hypothermia in EMS terms?

• A. 93.4°F (34°C) or lower
• B. 99°F (37°C) or lower
• C. 101°F (38.3°C) or higher
• D. 89°F (32°C) or higher

Answer: (A)

Hypothermia in EMS terms is defined by the core temperature dropping to about 34°C (93.2°F) or lower. When the body’s heat loss exceeds production and the core temp falls to this level, normal heat-generating mechanisms like shivering start to fail and metabolic processes slow, leading to confusion, slowed movements, and progressively serious effects on heart rate and breathing. The other options describe normal temperature, fever, or a much lower bound that would miss many cases of hypothermia, so the 34°C (93.2°F) or lower threshold is the best fit.
