# AI tells user to perform abdominal thrusts (Heimlich) on a pregnant or obese choking victim, but chest thrusts are recommended to avoid fetal injury or abdominal damage

## Root Cause

The AI fails to differentiate standard choking rescue from special populations; 2020 AHA and 2021 Red Cross guidelines explicitly state that abdominal thrusts on a pregnant woman (≥20 weeks) or obese person may cause uterine rupture, placental abruption, or internal organ damage, and chest thrusts should be used instead.

## Workarounds

1. **For pregnant or obese choking victim: stand behind them, place fist in middle of sternum (breastbone), grab fist with other hand, perform quick inward thrusts. Repeat until object is dislodged or victim becomes unconscious. Example command: 'Position your fist on the center of the chest, just above the xiphoid process, and thrust inward with force.'** (90% success)

2. **If victim becomes unconscious: lower to ground, begin CPR (30 compressions at 2-2.4 inches depth), check mouth after each cycle for visible object. Do not perform blind finger sweeps.** (85% success)

## Dead Ends

- **** — Performing abdominal thrusts on a pregnant woman can cause uterine rupture, especially in third trimester; risk of fetal hypoxia from decreased placental blood flow (90% fail)
- **** — Using back blows on a pregnant choking victim may be ineffective and cause harm; chest thrusts are preferred as they avoid the gravid uterus (60% fail)
- **** — Attempting finger sweeps in the mouth without visualization can push object deeper into airway (40% fail)
