Root Cause

Ice water immersion can cause peripheral vasoconstriction and shivering, which increases core body temperature and cardiac workload, potentially triggering arrhythmias in patients with underlying heart conditions or severe heatstroke; the correct protocol is cold water immersion (10-15°C) with continuous monitoring of heart rate and core temperature

冰水浸泡可能导致外周血管收缩和寒战，增加核心体温和心脏负荷，可能触发有基础心脏疾病或严重中暑患者的心律失常；正确方案是冷水浸泡（10-15°C）并持续监测心率和核心体温

Workarounds

90% success Use cold water immersion at 10-15°C (not ice water) with continuous monitoring of heart rate (ECG) and core temperature (rectal thermometer). Remove from water when core temperature reaches 38.5°C. Example: 'cold_water_immersion --temperature 12C --monitoring ecg --target_temp 38.5C'

85% success If immersion is not possible, use cold water dousing (pour cold water over the patient) while fanning the skin to enhance evaporative cooling. Example: 'cold_water_dousing --flow_rate 5L/min --fan_speed high --target_temp 38.5C'

```
80% success For patients with known heart conditions, use evaporative cooling (spray mist with fans) or ice packs placed on neck, armpits, and groin (high heat transfer areas) instead of full immersion. Example: 'evaporative_cooling --spray_water --fan_speed high --ice_packs neck,axillae,groin'

Dead Ends

Common approaches that don't work:

90% fail
Ice water triggers shivering, which generates heat and increases core temperature; vasoconstriction reduces heat loss from skin
85% fail
Without ECG monitoring, cardiac arrhythmias can go unnoticed and lead to cardiac arrest
80% fail
Immersion causes cold shock response, which can trigger arrhythmias in vulnerable patients
