Self-Assessment Questions

Emergency Medicine


Answer 1
  1. Evaporation. Humans primarily disperse heat by evaporation through the means of sweating.1 In the ED, evaporation can be maximized by undressing the patient, spraying or pouring warm water on the patient’s exposed skin, and propelling air over the skin with a fan. Cold water can induce vasoconstriction and therefore reduce potential heat loss.
