根因分析
AI未能区分标准窒息救援与特殊人群；2020年AHA和2021年红十字会指南明确指出对孕妇（≥20周）或肥胖者进行腹部冲击可能导致子宫破裂、胎盘早剥或内脏损伤，应改用胸部冲击。
English
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.

-
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.'
-
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.
无效尝试
常见但无效的做法:
-
90% 失败
Performing abdominal thrusts on a pregnant woman can cause uterine rupture, especially in third trimester; risk of fetal hypoxia from decreased placental blood flow
-
60% 失败
Using back blows on a pregnant choking victim may be ineffective and cause harm; chest thrusts are preferred as they avoid the gravid uterus
-
40% 失败
Attempting finger sweeps in the mouth without visualization can push object deeper into airway
