A heart attack can happen to anyone. Let’s say it’s 5:20 pm and you’re driving home alone after an unusually hard day on the job. You’re really tired, upset and frustrated. Suddenly, you start experiencing terrible pains in your chest, and they spread to your arm and up into your jaw. You are only about five miles from the hospital which is nearest your home. Unfortunately, you don’t know if you’ll be able to make it that far. You’ve been trained in a CPR course, but the guy who teaches the course hasn’t told you how to perform it on yourself. What can you do?

Since many people are alone when they suffer a heart attack, this article seems to be quite useful. Without help, people whose hearts stop beating properly and who begin to feel faint (头晕的) have only about 10 seconds left before they faint. However, they can help themselves by coughing over and over very loudly. A deep breath should be taken before each cough, and the cough must be deep and prolonged, coming from inside the chest. Deep breaths and coughing must be repeated about every two seconds without stopping until help arrives, or until the heart is felt to be beating normally again. Deep breaths get oxygen into the lungs and coughing movements squeeze (挤压) the heart and keep the blood circulating. The squeezing pressure on the heart also helps it beat normally. In this way, people who are suffering a heart attack can get to a phone and between breaths call for help.

Tell as many other people as possible about this, as it may save their lives!
