同学们,让我们争做健康安全小卫士,传播健康安全的理念!请学习以下介绍心肺复苏术的宣传海报,并查阅与海姆利希急救法相关的资料,结合所学知识,设计一张介绍海姆利希急救法的英文宣传海报,普及安全救助的方法。

示例英文海姆利希急救法宣传海报：
标题：Heimlich Maneuver (Choking First Aid)
步骤：
1. C (Compressions)
Adult: Stand behind the victim, put arms around waist, make a fist, place it above the navel (below ribcage), hold the fist with the other hand, push hard and fast inward-upward 5 times.
Infant: Place 2 fingers on the center of the infant’s chest, push hard and fast 5 times.
2. A (Airway Check)
Open the victim’s mouth, check for visible foreign objects, remove them gently if present.
3. B (Breathing Check)
See if the victim can cough, speak or breathe; if not, repeat the above steps.

本题为开放性实践题目，要求参考心肺复苏术（CPR）的科普海报形式，结合海姆利希急救法（针对气道异物梗阻的急救方法）的知识，设计英文宣传海报，需明确核心步骤，用英文清晰标注，内容准确易懂，符合急救规范。
