# AI advises using ice water immersion for heatstroke treatment without warning about cardiac arrhythmia risk, or suggests giving oral fluids to an unconscious heatstroke victim

## Root Cause

Ice water immersion can cause shivering (which generates heat) and may trigger cardiac arrhythmias in heatstroke patients with compromised cardiovascular systems; oral fluids given to an unconscious patient risk aspiration and airway obstruction.

## Workarounds

1. **For heatstroke (core temp >40°C with altered consciousness): 'Call 911 immediately. Move patient to shade. Cool by immersing in cold water (10-15°C, not ice water) if possible, or apply cold packs to neck, armpits, and groin. Fan aggressively. Do NOT give oral fluids if unconscious. Monitor for shivering and cardiac changes.'** (90% success)

2. **For heat exhaustion (core temp <40°C, conscious): 'Move to cool area, loosen clothing, give cool water or sports drink slowly. Apply cold compresses. If symptoms worsen or last >1 hour, seek medical help.'** (95% success)

## Dead Ends

- **** — Ice water can cause peripheral vasoconstriction (reducing heat loss), shivering (increasing heat production), and cardiac arrhythmias. Cold water (10-15°C) is preferred over ice water, and cooling should be monitored. (85% fail)
- **** — Unconscious patients cannot swallow safely; fluids can enter the airway, causing aspiration pneumonia or choking. IV fluids are required for severe cases. (95% fail)
- **** — Alcohol can be absorbed through skin and cause toxicity; cold packs on extremities cause vasoconstriction, reducing heat dissipation. Apply cold packs to neck, armpits, and groin instead. (75% fail)
