Compare the following two paragraphs, which one do you think better, and explain your reasons. A When a person has something in his air passage which causes severe congestion, a potential method you can employ is the Heimlich maneuver. This technique, when applied properly, is the most effective way to save the life of a choking victim. The principle behind the maneuver is not intricate or complicated at all. Even when a foreign object is lodged in the windpipe, there is still enough air left in the lungs to dislodge the object if the air is forced upward in an abrupt manner. The purpose of the Heimlich maneuver is to initiate a strong enough burst of air from the primary respiration organ to free the objects blocking the windpipe. B When a person has something caught in the throat, you can save his life by the Heimlich maneuver. This is a technique widely used to help people breathe when they choke on food or some other objects. If you use it properly, you can easily save a life. The theory behind the method is quite simple. Even when an object gets stuck in the throat, there is sill enough air let in the lungs to remove that object. You just need to force out the air upward suddenly. That is exactly what you do by applying the Heimlich maneuver, that is, to create a strong enough burst of air from the lungs to free whatever is stuck in the throat.
