A little more than five years ago Robert Schriever, a football and lacrosse referee, dropped dead during a game.
"I just blew the whistle, and took two and a half steps and down I went. That's all I remember," Schriever recalled.
An automated external defibrillator, or AED, saved his life.
For that he's grateful.
But what if there isn't one readily available?
That's where something like the Pocket CPR could come in handy.
Simply turn on the device and it will coach you.
If they're not getting air you place the device on the person's chest and start performing CPR.
"It requires somewhere in excess of 75 pounds pressure to deliver good compressions and this device gives you that feedback," explained Mark Totman.
He's president of Bio-Detek, the company that makes the Portable CPR.
For years the company has made electrodes for AEDs and EKGs.
Emergency room physician Dr. David Barash was an advisor on the portable CPR device.
He realized the great need for making CPR convenient to do, and for folks performing this lifesaving maneuver the right way.
"They don't do it hard enough and they don't do it fast enough. One, it gives someone the confidence that they can do CPR, it coaches them while they do CPR and two, is it actually monitors their CPR so they're doing it effectively," Dr. Barash explained.
Robert Schriever's sold on the device.
