Robert Bernahl, Jeff's father, had walked into the living room of their home and asked Jeff and his sisters if they wanted to play cards. Then he walked back toward the kitchen, only to collapse.

"I thought Dad was kidding," Jeff said. He soon realized, however, that something was very wrong, and that his father was not breathing.

Jeff's father's heart had stopped beating. Jeff's mother, a registered nurse, began mouth-to-mouth resuscitation, while Jeff began compressing his father's chest.

"At first I wasn't sure if I remembered how to do it, but it just came back to me as soon as I started. You have to find the landmark toward the end of the ribs."

Paramedics who arrived on the scene said that Mr. Bernahl is probably alive today because of the quick actions of his son and wife -and that Jeff had obviously learned his CPR training very well.
