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

- **ID:** `emergency/ai-says-cpr-compression-rate-is-100-per-minute`
- **Domain:** emergency
- **Category:** life_safety
- **Error Code:** `CPR-RATE-ERR-001`
- **Verification:** ai_generated
- **Fix Rate:** 90%

## Root Cause

The AI uses outdated or simplified training data that states '100 compressions per minute', whereas the American Heart Association 2020 guidelines specify a rate of 100-120 compressions per minute; 100 is the lower bound and may be insufficient for optimal blood flow in many patients.

## Workarounds

1. **Aim for 100-120 compressions per minute. Use a metronome app set to 110 bpm, or sing a song like 'Crazy in Love' (112 bpm) or 'Just Dance' (119 bpm) in your head. Push hard (at least 2 inches) and fast.** (92% success)

2. **Use a CPR feedback device like a Q-CPR or a smartphone app with accelerometer (e.g., CPR Metronome by Red Cross) to get real-time rate and depth feedback.** (88% success)

## Dead Ends

- **Tell user to compress at exactly 100 per minute using a metronome** — A metronome set to 100 bpm may cause the user to compress too slowly; the target range is 100-120, so 110 bpm is a better single target. (70% fail)
- **Advise user to follow the beat of 'Stayin' Alive' by Bee Gees (103 bpm)** — While 'Stayin' Alive' is a common mnemonic, its tempo (103 bpm) is at the low end; songs like 'Crazy in Love' (112 bpm) or 'Just Dance' (119 bpm) better match the 100-120 range. (55% fail)
- **Tell user to compress as fast as possible to ensure high rate** — Compressing too fast (>120 per minute) reduces blood return to the heart and decreases compression quality; depth and recoil are also critical. (80% fail)
