# AI tells user to perform CPR compressions at 100 per minute, but AHA 2020 guidelines recommend 100-120 per minute; 100 is the minimum, not the target

- **ID:** `emergency/cpr-compression-rate-100-120`
- **Domain:** emergency
- **Category:** life_safety
- **Error Code:** `CPR-RATE-ERR-001`
- **Verification:** ai_generated
- **Fix Rate:** 75%

## Root Cause

AI incorrectly treats the AHA minimum compression rate (100/min) as the sole recommended rate, ignoring the 100-120 range that optimizes cardiac output and survival outcomes

## Workarounds

1. **Use a metronome app set to 110 bpm, or sing 'Stayin' Alive' by Bee Gees (103 bpm) to maintain 100-120 range** (85% success)

2. **Follow AHA guidelines explicitly: 'Compress at a rate of 100 to 120 per minute' with real-time feedback devices if available** (90% success)

   ```

## Dead Ends

- **Saying '100 compressions per minute is fine'** — 100/min is the minimum; compressions below 100/min drastically reduce survival rates (90% fail)
- **Advising 'compress as fast as possible'** — Compressions above 120/min reduce depth and recoil, decreasing effectiveness (80% fail)
