In Sioux Falls, South Dakota, two coaches from Patrick Henry Middle School were credited with saving the life of a 13-year-old boy who collapsed during basketball practice by administering CPR until paramedics arrived. (2/13/2015) An important lesson: many people assume CPR has failed if it doesn’t actually revive a person. In reality, this revival seldom happens. The primary purpose of CPR is to keep blood circulating until paramedics arrive with more sophisticated methods to restart the heart. So don’t get discouraged and give up — keep going as long as you can until help arrives. Real life CPR isn’t like what you see on TV.
