  • Mild hypothermia: core temperature 32 to 35°C ; patient presents with confusion, tachycardia, and increased shivering.
  • Moderate hypothermia: 28 to 32°C patient presents with lethargy, bradycardia and arrhythmia and decreased shivering.
  • Severe hypothermia: below 28°C patient presents with coma, hypotension, arrhythmia, pulmonary edema, and rigidity.
