You may have only few seconds to save a life when you in an emergency. Is anything you can do in an emergency until help arrives? You should do, because the only person you may have to depend on is yourself. First aid is the immediate care given to a victim of injury or sudden illness before professional medical help arrives. Cardiopulmonary resuscitation (CPR) is a method of combining chest compressions with rescue breathing to maintain a flow of oxygen-rich blood to the brain while the heart is not working. .
About half a million people in the United States suffer a heart attack each year. Heart attack occurs when some of the tissue in the heart is prevented from receiving its normal blood supply and dies. If the victim is conscious, put his in a half-sitting position, with head and shoulder supported with pillows, and knees bent. And also call 911, loosen the patient's clothing around the neck, chest and waist to help circulation and ease his breathing. If the victim becomes unconscious, start CPR. .
One of the most popular injuries happen of teenagers is sling. When your friends brake their arms outside, first you have to do is getting the victim to support the injured arm with his hand. Take the lower end of the bandage up over the hand forearm and tie it in the hollow just above the collarbone. Pin the point near the elbow, or twist and tuck it in. .
CPR fell out of practice until it was rediscovered in the 1950s. modern CPR developed in the late 1950s and early 1960s. The discoverers of mouth-to-mouth ventilation were Drs. James Elam and Peter Safar. Though mouth-to-mouth resuscitation was described in the Bible (mostly performed by midwives to resuscitate newborns.) In early 1960 Drs. Kouwenhoven, Knickerbocker, and Jude discovered the benefit of chest compression to achieve a small amount of artifical circulation. Later in 1960, mouth-to-mouth and chest compression were combined to form CPR similar to the way it is practiced today.
