As National CPR Week ends, a shining example of how it can save lives.
A man working out at a gym in San Luis Obispo suffered a massive heart attack back in April. The actions of the people around him are the reason he's alive to tell his story.
"I got immediate CPR from my friends here at MZR when I went down," Bob Fialkowski said.
It was like any other morning workout at MZR Fitness until the unthinkable happened. Fialkowski doesn't remember the moment he had the heart attack, but those who jumped in to save his life will never forget it.
"It was definitely a scary situation, but it was one of those situations that you just start doing and you go with it and hope that your training pays off," Dr. Vik Tiku said, a local pediatric dentist.
He and one of the MZR Fitness trainers - both CPR certified - performed the life saving technique in those first critical minutes until help arrived.
"So in just the first few minutes that's really critical to have the blood circulate to keep the brain alive, and keep the lungs, the heart alive," San Luis Ambulance Paramedic Kris Strommen said.
With their efforts, Fialkowski is on the road to recovery.
The owner of MZR Fitness held a fundraiser this past weekend to help raise money for Fialkowski's mounting medical bills and also provided CPR demonstrations through San Luis Ambulance.
"If something happened to your husband or your wife or grandparents or kids, whoever, just to be able to have that ability to step in if you need to," MZR Fitness Owner Mike Robinson said.
Paramedics taught hands-only CPR, which is a form that even if you are not certified you can still perform on a cardiac patient.
"And makes it as simple as possible, just pushing on the chest 100 times a minute," Strommen said.
As for Fialkowski, doctors also credit the quality of CPR he received for his remarkable recovery.
"You can't say thank you enough ... we're definitely bonded forever," he said.
Robinson said of the 30 people in the room that day of Fialkowski's heart attack 16 were CPR certified and 14 have gotten certified since.
