Potomac mom Laura Metro has become a CPR party hostess.

“My son Clay almost died by drowning. He was at the pool with some of our friends and he was walking from one friend to the next to go get a snack and we believe he tripped on his towel and fell in the deep end. I didn’t know CPR and I couldn’t understand as a responsible, I felt as a safety conscious mom how and why I didn’t know CPR,” Metro said.

Laura’s son Clay is 9-years-old now and he was 3 at the time of the accident.

“When seconds count, the paramedics can’t get there on time, it’s impossible. There is too much land to cover, so if no one around knows these skills, they are going to die,” she aid.

The group Rescue One partners with Metro.

“We have had about 150 classes nationwide, a lot of them here in the Washington area,” Jeremy Gruber said.

Marianne Beardall has her own four children in mind.

“It’s very important that I have the base just in case something happens,” she said.

Laura’s son Clay was saved thanks to a friend who performed amateur CPR until paramedics arrived.

“That ultimately is their explanation for why he is cognitively OK today,” Metro said.

The scare was a wake-up call for Metro who quickly became CPR certified.

Laura’s son Clay has also learned CPR.

Metro has hosted CPR parties since 2012.
