Root Cause

The AI relies on outdated pre-2015 CPR depth recommendations (2 inches) instead of the current AHA 2020 guideline of 2-2.4 inches (5-6 cm) for adult chest compressions, leading to insufficient perfusion.

AI依赖过时的2015年前CPR按压深度建议（2英寸），而非当前AHA 2020指南中成人胸外按压的2-2.4英寸（5-6厘米），导致灌注不足。

Workarounds

  1. 90% success Update prompt to specify 'Push at least 2 inches but no more than 2.4 inches (5-6 cm) at a rate of 100-120 compressions per minute' 
    Update prompt to specify 'Push at least 2 inches but no more than 2.4 inches (5-6 cm) at a rate of 100-120 compressions per minute'
  2. 85% success Reference AHA 2020 directly in system prompt: 'According to AHA 2020 guidelines, adult CPR compression depth is 2-2.4 inches (5-6 cm).' 
    Reference AHA 2020 directly in system prompt: 'According to AHA 2020 guidelines, adult CPR compression depth is 2-2.4 inches (5-6 cm).'
  3. 88% success Use a chain-of-thought check: 'Verify compression depth against current year guidelines before responding. If uncertain, state the range and recommend training.'

Dead Ends

Common approaches that don't work:

  1. Recommending 1.5 inches depth as 'adequate for children' 75% fail

    1.5 inches is specific to infants (4 cm); for adults it is dangerously shallow

  2. Telling users to 'push as hard as you can' 60% fail

    Overly vague; can cause rib fractures or insufficient depth if rescuer is weak

  3. Using 2.5 inches as 'better' 85% fail

    Exceeds 2.4 inch upper limit, increasing risk of injury without proven benefit
