Article: Can you imagine that you can save your own life during a heart attack by coughing ? Let's see how... A heart attack can happen to anyone. Let's say it's 4:17 p.m. and you're driving home (alone of course) after an unusually hard day on the job. Not only was the workload extremely heavy, you also had a disagreement with your boss, and no matter how hard you tried, he just wouldn't see your side of the situation. You're really upset and the more you think about it, the more nervous you become. All of a sudden you start experiencing severe pain in your chest that starts to spread out into your arm and up into your . You are only about five miles from the hospital nearest your home, unfortunately you don't know if you'll be able to make it that far. What can you do? You've been trained in CPR but the guy who taught the course didn't tell you how to perform it on yourself. Since many people are alone when they suffer a heart attack, this article seems in order. Without help the person whose heart stops beating properly and who begins to feel has only about 10 seconds left before losing consciousness. However, these victims can help themselves by coughing repeatedly and very powerfully. A deep breath should be taken before each cough, and the cough must be deep and last long, as when producing from deep inside the chest. A breath and a cough must be repeated about every two seconds without stopping until help arrives, or until the heart is felt to be beating normally again.

In this way, heart attack victims can get to a phone and, between breaths, call for help. Now, do you understand the whole matter? Tell as many other people as possible about this. It could save their lives!
