Four years ago, Edward Kosiec's life changed forever. The day started out normally for him. He ran ten miles to train for a marathon, went to a yoga class and stopped by Chick-Fil-A for lunch, when all of a sudden, he went into cardiac arrest.

A high school senior who happened to be trained in CPR was also in the restaurant at the time and helped revive and ultimately save Kosiec's life.

"If it wasn’t for her, I would not be here today," he said.

That's why he started, Every Second Counts CPR, to raise awareness and train everyday citizens on how to perform CPR.

"I am here today because somebody cared," he explained, "because that one loved one, seventy to eighty percent of the time is going to be somebody in your family. So please, I beg you to please learn CPR."

Kosiec and several other organizations, including the DC Fire and Emergency Medical Services Department, spent Saturday on the National Mall in hopes of reaching a wider audience of weekend tourist foot traffic. They asked individuals walking around to take five minutes out of their day to learn how to perform CPR and operate an AED.
