Root Cause

The AI fails to differentiate special populations: abdominal thrusts can injure the fetus or be ineffective due to abdominal girth; AHA/ERC guidelines recommend chest thrusts for pregnant or obese victims

中文

AI未能区分特殊人群：腹部冲击可能伤害胎儿或因腹部周长而无效；AHA/ERC指南推荐对孕妇或肥胖者使用胸部冲击

Workarounds

  1. 85% success For pregnant or obese victim: Stand behind victim, place fist on middle of sternum (breastbone, at nipple line for non-obese; adjust to sternum midline for obese). Perform chest thrusts inward and upward, similar to abdominal thrusts but on chest. Use same rhythm: 5 back blows, 5 chest thrusts, alternating. Example: 'Position fist at center of chest, thrust inward 5 times, check airway, repeat.'

Example: 'Position fist at center of chest, thrust inward 5 times, check airway, repeat.'
  2. 90% success If victim is unconscious: Lower to ground, begin CPR (chest compressions) which can dislodge obstruction. For pregnant, tilt uterus to left (15-30 degrees) to improve cardiac output. Do not perform abdominal compressions.

  3. 75% success For obese with large abdomen: Use a step-stool or have victim lean over a table to allow better access to chest. Ensure thrusts are directed inward and upward at sternum midline.

中文步骤

  1. 对于孕妇或肥胖者：站在受害者身后，将拳头放在胸骨中部（胸骨，非肥胖者在乳头线；肥胖者调整至胸骨中线）。向内向上进行胸部冲击，类似腹部冲击但位于胸部。使用相同节奏：5次背部拍击，5次胸部冲击，交替进行。示例：'将拳头置于胸骨中心，向内冲击5次，检查气道，重复。'
  2. 如果受害者失去意识：将其平放，开始CPR（胸外按压），这可以驱除梗阻。对于孕妇，将子宫向左倾斜（15-30度）以改善心输出量。不要进行腹部按压。
  3. 对于腹部巨大的肥胖者：使用垫脚凳或让受害者俯身于桌子以更好接触胸部。确保冲击向内向上指向胸骨中线。

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Abdominal thrusts compress the uterus, risking placental abruption, uterine rupture, or fetal injury; the diaphragm is also displaced upward, reducing effectiveness

  2. 70% fail

    Back blows alone are insufficient for severe obstruction; they should be alternated with chest thrusts, not used as sole treatment

  3. 80% fail

    Self-Heimlich is not recommended for pregnant/obese due to same risks; also may cause abdominal organ injury
