Consequently, safe circulatory arrest times for mild and moderate hypothermia are only 10 and 20 minutes respectively. [32] While moderate hypothermia may be satisfactory for short surgeries, deep hypothermia (20 °C to 25 °C) affords protection for times of 30 to 40 minutes at the bottom of this temperature range.
Other than a low body temperature, signs of hypothermia include feeling cold, sluggish, slurred speech, disorientation, uncontrolled shivering or having trouble thinking clearly. Hypothermia is ...
Hypothermia and extreme stress can both precipitate fatal tachyarrhythmias. A more modern view suggests that an autonomic conflict – sympathetic (due to stress) and parasympathetic (due to the diving reflex) coactivation – may be responsible for some cold water immersion deaths.
