根因分析
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
English
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

-
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。'
-
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。
-
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。
无效尝试
常见但无效的做法:
-
95% 失败
Abdominal thrusts compress the uterus, risking placental abruption, uterine rupture, or fetal injury; the diaphragm is also displaced upward, reducing effectiveness
-
70% 失败
Back blows alone are insufficient for severe obstruction; they should be alternated with chest thrusts, not used as sole treatment
-
80% 失败
Self-Heimlich is not recommended for pregnant/obese due to same risks; also may cause abdominal organ injury
