Chris Favorin of York Haven, Pennsylvania, was in the middle of a workout on August 5 when he started to feel unwell. At a subsequent press event, he said, “I was finishing up doing a set of 100 jumping jacks when about halfway through I couldn’t lift my arms past my shoulders and started to feel real tightness in the chest.”

Over 805,000 people in the U.S. have a heart attack each year, which means someone has a heart attack every 40 seconds, according to the U.S. Centers for Disease Control and Prevention.

While Favorin and his fiancée looked for the nearest medical clinic, they remembered that their neighbor works in health care. Noticing that both cars were in the driveway, he approached the house.

Christopher Mowry has been a career firefighter for the past 14 years at York Area United Fire and Rescue, while his wife, Rachel, is a nurse practitioner with Wellspan Health Urgent Care and works occasionally in a hospital emergency room.

Footage from the video doorbell shows Favorin walking up to the Mowrys’ porch, ringing the doorbell and then getting down on his hands and knees in obvious distress.

When the couple answered the door and found Favorin, they immediately called 911. Moments later, when Favorin went into cardiac arrest, the couple sprang into action to perform life-saving CPR.

Christopher Mowry told Newsweek: “When we first encountered Chris we could tell his situation was serious. We just followed what we knew and did what we could, having no equipment.

“We began assessing him and his chest pain right away, we activated 911, sent his fiancée to retrieve some baby aspirin, and did what we could for the initial issue. As things progressed we just did what we are trained to do,” Mowry said.

When paramedics arrived, they used a defibrillator, and 14 minutes later Favorin’s pulse resumed. Rachel rode in the ambulance to the hospital. Favorin’s pulse stopped a second time but resumed before they reached the emergency room, where he was treated.

Just weeks away from his wedding, Favorin is making a full recovery thanks to the Mowrys’ fast actions and the care he received at the hospital,

After discovering that their security camera had recorded the entire event, the Mowrys and Favorin agreed to release the footage.

“Our ultimate goal was simply to share with our friends and neighbors what happened, simply organize a CPR class and stress the importance of knowing CPR,” Mowry said.

Statistics show that nearly 383,000 out-of-hospital sudden cardiac arrests occur annually. But according to research, 70 percent of Americans say they would feel helpless to act during a cardiac emergency because they do not know how to administer CPR or their training has significantly lapsed.

“The bottom line is anyone can know and administer CPR,” said Mowry. “Remove my wife and I’s careers from the equation and anyone could have done what we did simply by knowing and administering proper CPR. It’s a skill that everyone should have in their back pocket.”

Following the incident, the Mowrys informed their neighbors that the University of Pittsburgh Medical Center (UPMC) is offering six free CPR classes to the community, which has more than 180 residents signed up to become certified.

“The reaction got much bigger than anticipated,” Mowry said. “In the big picture, Rachel and I simply did our jobs as the public would expect.”

He credited the teamwork of LifeTeam UPMC EMS, the Newberry fire department and the Newberry police for helping on that day.

“Everyone involved all agree if we can inspire people to take a CPR class and just one person saves a life, our purpose is met. CPR certification just takes a small amount of time from your day and can change a life forever,” Mowry said.
