How to Use This Calculator

Enter the Core Temperature (degrees C) — measured by esophageal or bladder probe for accuracy.
The calculator automatically assigns Hypothermia Stage based on core temperature.
Review Recommended Rewarming Rate (degrees C/h) — avoid rewarming too rapidly to prevent afterdrop.
Check Cardiac Risk level — severe/profound hypothermia requires continuous cardiac monitoring.
Select Intervention (Passive external, Active external, Active internal, or ECMO) based on stage and cardiac status.
