VIDEO: A quick CPR lesson and an app could be all it takes to save a nearby person's life. Wake County EMS District Chief M. Wells demonstrated chest compressions a person would use on someone whose heart has stopped. He reminded people that even if they think they're not strong enough or are afraid of hurting the person, it's still worth it to perform CPR. "Even if I'm not compressing it an inch and a half to two inches — even if I'm small compared to this person's size — I'm still doing more for them than they are for themselves," Wells said. It only takes a few minutes to learn CPR. The same amount of minutes can also save a life. People might not always know when someone else needs help. That's where the PulsePoint app comes in. It will soon plug directly into Wake County dispatch. The alert says that someone close by is in need of CPR. It will show a person on the phone exactly where someone in need is. A person can then go right over and give chest compressions while waiting for emergency responders.
