I took a first aid course last week. We learned how to help people in trouble. One of the things we learned was how to help someone who is choking. Our teacher gave us a useful sheet to help us remember the steps. Here's what she gave us:

FIRST AID FOR CHOKING

Signs that a person might be choking:
• The person cannot breathe, cough, or speak.
• The person makes an "I'm choking: sign with his or her hands.
• The person's lips turn blue.

Step 1. Ask, "Are you choking?"
Step 2. If the person signs "yes," step behind the person, and put your arms around his or her waist.
Step 3. Close one hand and hold it with the other. Place your hands just above the person's belly button.
Step 4. Pull sharply towards yourself.
Step 5. Repeat until the object comes out or the person can breathe.

我上週參加了急救課程，學到如何幫助有難之人的方法。其中一項就是如何協助噎到的人。我們老師發了一張實用的講義，有助於我們記得步驟。以下是講義內容：

哽噎的可能情況：
● 患者無法呼吸、咳嗽或講話。
● 患者以雙手示意「我噎著了」的樣子
● 患者嘴唇發紫。

步驟1 詢問「你噎到了嗎？」
步驟2 如果患者示意回應「是的」，請站在他/她的後方，將你的雙手環繞於他/她的腰部。
步驟3 雙手手掌互扣，並放於此人的肚臍正上方。
步驟4 往你自己的方向用力擠按患者。
步驟5 重複動作，直到患者吐出異物或可呼吸為止。
