Root Cause

The AI fails to recognize that abdominal thrusts on a pregnant woman risk uterine trauma, placental abruption, or fetal injury, and on an obese person may be ineffective due to abdominal mass; chest thrusts (similar to CPR compressions) are the standard alternative for these populations.

AI未能认识到对孕妇进行腹部冲击可能导致子宫创伤、胎盘早剥或胎儿损伤，而对肥胖者可能因腹部质量而无效；胸部冲击（类似CPR按压）是这些人群的标准替代方案。

Workarounds

  1. 90% success For a pregnant or obese choking victim who is conscious and cannot cough/speak/breathe: Stand behind the victim, place one fist (thumb side in) on the lower half of the sternum (breastbone), grasp with the other hand, and perform quick inward thrusts at the same rate as CPR compressions (100-120/min). Continue until the object is expelled or the victim becomes unconscious.

Continue until the object is expelled or the victim becomes unconscious.
  2. 85% success If the victim is unconscious: Lower them to the ground, call 911, and begin CPR. Each time you open the airway to give breaths, look for the obstructing object. If visible, remove it with a finger sweep (only if visualized). Chest compressions themselves can sometimes dislodge the object.

Dead Ends

Common approaches that don't work:

  1. Tell user to perform back blows first on pregnant victim 60% fail

    Back blows are only recommended for infants under 1 year; for adults, they are not part of the conscious choking protocol and may delay effective chest thrusts

  2. Advise to modify abdominal thrust by pushing higher on the abdomen 90% fail

    There is no safe 'higher' location for abdominal thrusts on a pregnant woman; any force on the abdomen risks fetal harm; the correct technique is chest thrusts at the sternum

  3. Recommend using a finger sweep to remove the object 95% fail

    Blind finger sweeps are contraindicated in all modern choking guidelines (AHA 2020, Red Cross) as they can push the object deeper into the airway
