How Bystander CPR Saves Lives in Emergencies

Many lives could be saved with proper CPR training, as timely intervention during a cardiac arrest significantly improves survival rates. A report highlights that despite high incidences of such emergencies, readiness is lacking. Easy access to AEDs and training resources, alongside awareness, are crucial in preventing unnecessary deaths from cardiac arrests.

When I was in medical practice, I stayed current in CPR certification. Fortunately, I never had to use it in the office and only once in a public place, a church.

But I have not updated my certification since leaving practice. But after reading this article from KFF, I reviewed CPR in a video.

A video is better than nothing, but if you have never taken a formal CPR class, I recommend it, especially if you are a caregiver for children or people at risk of heart disease, which is everyone.

I’m sharing this article and graphics to explain why CPR knowledge is so vital.

Fast Action From Bystanders Can Improve Cardiac Arrest Survival.

Many Don’t Know What To Do.

Written by Michelle Andrews, April 30, 2025

When a woman collapsed on an escalator at the Buffalo, New York, airport last June, Phil Clough knew what to do. He and another bystander put her flat on her back and checked her pulse (faint) and her breathing (shallow and erratic). Then she stopped breathing altogether.

Realizing that she might be having a cardiac arrest, Clough immediately started doing chest compressions, pressing hard and quickly on the center of her chest, while others nearby called 911 and ran to get an AED, automated external defibrillator.

Within seconds of receiving a shock from the AED, the woman opened her eyes. By the time the airport rescue team arrived a few minutes later, she was conscious and able to talk with rescuers.

“I don’t want to ever feel helpless,” said Clough, who had flown to Buffalo that evening on a work trip for his engineering job in Denver. After an incident several years earlier in which he was unsure how to help a woman who collapsed at his gym, he took a college course to get certified as an emergency medical responder, who can provide basic life support interventions.

The woman who collapsed was lucky: She lost consciousness in a public place where bystanders knew how to help her. Most people aren’t so fortunate.

In the United States, a lack of training and readiness to deal with this relatively common medical emergency contributes to thousands of deaths a year.

What is a cardiac arrest?

More than 350,000 cardiac arrests occur outside of a hospital setting in the United States annually, according to the American Heart Association. In 9 of 10 cases, the person dies because help doesn’t arrive quickly enough.

Every minute that passes without intervention reduces the odds of survival by 10%. But if someone immediately receives cardiopulmonary resuscitation and an AED shock, if needed, their survival odds can double or even triple.

Fewer than half of people get that immediate help, according to the AHA. A cardiac arrest occurs when the heart stops suddenly, often because the heart’s electrical system malfunctions. About 70% of cardiac arrests occur at home.

But even if someone collapses in a public place and an ambulance is called immediately, it takes roughly eight minutes, on average, for emergency personnel to arrive. In rural areas it can take much longer.

When someone has a cardiac arrest, they often require an electric shock from an AED to get their heart started again. These portable devices analyze the heart’s rhythm and instruct the user to deliver a shock, if necessary, through pads placed on the victim’s chest.

Where are the AEDs ?

But although many states require AEDs in public places such as airports, malls, and schools, they often aren’t easy to spot. A study of data from 2019 to 2022 found that after a cardiac arrest in a public place, bystanders used an AED 7% of the time and performed CPR 42% of the time.

The most comprehensive resource for identifying AEDs is a nonprofit foundation called PulsePoint, which has registered 185,000 AEDs in 5,400 communities in the United States. (Shannon Smith, PulsePoint vice president of communications).

If requested, the organization will help a community build its AED registry and connect it to the area’s 911 service free of charge.PulsePoint recently launched a national AED registry to further this effort.

Through a companion app, users trained in CPR can volunteer to be alerted to potential cardiac arrests within roughly a quarter-mile when calls come into a community’s emergency response dispatch service. The app also identifies registered AEDs nearby.

“PulsePoint is the closest thing we have to a national registry,” said Elijah White, president acute care technology at Zoll, a leading AED manufacturer. The company has provided location information for all its AEDs to PulsePoint. Still, PulsePoint has registered only a fraction of AEDs in the country. “It’s just a start,” White said.

Other factors may also keep bystanders from stepping in to help. They may lack CPR training or confidence, or fear liability if something goes wrong.

What are barriers to CPR?

Liability shouldn’t be a concern, in general. All 50 states and Washington, D.C., have “good Samaritan” laws that protect bystanders from legal liability if they intervene in a medical emergency in good faith.

But training can be a serious barrier. One study found that only 18% of people reported that they’d received CPR training within the previous two years, a key time frame for skills maintenance. Two-thirds of people reported having been trained at some point.

One way to boost training is to make it mandatory, and many states require CPR training for students to graduate.

But even though 86% of high school students reported having received some training, only 58% said they knew how to apply their skills, and a similar proportion said they knew how to use an AED.

“We’ve got some work to do,” said Dianne Atkins, a pediatric cardiologist and longtime AHA volunteer, who said ensuring high school training is a top priority for the AHA.

Other countries have prioritized training their residents in AED use and CPR for many years, with some success.

In Denmark requires training to get a driver’s license, and middle schoolers are trained. A survey found 45% of the population reported having received training through their workplace. In the study, 81% of respondents in the general public reported having been trained in CPR and 54% in how to use an AED.

Norway has provided first-aid training in primary schools since 1961 and mandates CPR training for a driver’s license. Ninety percent of the population reported they are trained in CPR.

In the United States,  many training courses are available, online and in person, that take only a few hours . For someone who’s never learned basic life-support skills, the training can be eye-opening.

This previously untrained reporter was taken aback to discover how forcefully and rapidly someone must press on a mannequin’s chest to do CPR correctly: 100 to 120 compressions a minute to a depth of at least 2 inches.

The most important thing is for ordinary people to know the basics well enough that “they would feel confident to call 911 and push hard and fast on someone’s chest,” said Audrey Blewer, an assistant professor of family medicine and community health at Duke University School of Medicine. She has published numerous studies on bystander CPR and AED use. “That doesn’t require a certification card and recent training.”

During an emergency, 911 dispatchers can also play a crucial role in walking people through doing CPR and operating an AED, said David Hiltz, volunteer program director of the HeartSafe Communities program at the Citizen CPR Foundation, a nonprofit that works to improve cardiac arrest survival through training and education.

Phil Clough has stayed in touch with Rebecca Sada, the woman who collapsed at the Buffalo airport that June day as she was coming home from a trip to visit her daughter.

Needing an Internal Defibrillator

Sada, who had no history of heart trouble before her cardiac arrest, now has an automated defibrillator implanted in her chest to stabilize a previously undiagnosed electrical problem with her heart. An implantable cardioverter-defibrillator, an ICD, is a small battery-powered device placed in the chest. It detects and stops arrhythmias, irregular heartbeats. An ICD constantly checks the heartbeat. It delivers electric shocks, when needed, to restore a regular heartbeat.

She and her husband invited Clough for dinner, and they are friends for life, she said. One other change that occurred as a result of Sada’s cardiac arrest: She and her husband got certified in CPR and AED.

“Now, if we needed to help someone down the road, we’d be able to,” Sada said.

Keith Wheeler-a Cross and a Heart

Keith Wheeler posted a joyous New Year message, but faced unexpected health challenges in January 2024. Diagnosed with severe heart blockages, he bravely confronted surgery with unwavering faith, surrounded by love and prayers. Just days after the procedure, Keith was already inspiring others with his recovery and gratitude for life’s blessings.

Happy New Year! Happy 2024!

We pray that your new year will be overflowing with the beauty and majesty of the glory of Jesus, and the nearness and intimacy of His presence!

God bless you!

Keith Wheeler, Facebook post January 2, 2024

But the rest of January didn’t quite turn out the way Keith and his fairytale princess wife Nicole planned. In some ways, it turned out much better.

I have been writing this blog for nine years and my favorite posts are the ones I wrote about Keith Wheeler, starting with this one.

Keith Wheeler- a cross and a collarbone

Keith walks around doing what he simply calls “serving God, loving people.” He started in Tulsa, Oklahoma on Good Friday 1985 and thought it was going to be a one-time event. But he felt God wanted him to continue carrying the cross around the surrounding towns, then the rest of Oklahoma, and on into surrounding states. And then he just kept walking- and carrying the cross.

Keep reading

After he experienced a bout with COVID-19, I wrote another article based on an interview we did by phone. It’s hard to interview Keith because he doesn’t like talking about himself. His favorite subject is Jesus. What else would you expect from a man who has literally walked around the world carrying a 12-foot-long cross?

Keith Wheeler-a Cross and COVID

No, I wasn’t mad at God, I know that bad things happen to everyone. Jesus said that whoever wants to save their life should lose it, (Luke 9:24) so I know that either way I would be with Him. Jesus is my hope, my confidence, and peace, in all my life, including COVID.

I finally met Keith in person when he spoke at a church near my home. I don’t know which I enjoyed most- shaking hands with him or touching the massive cross that has been all over the world blessing everyone who sees or touches it.

A Heart and a Hospital

So I was alarmed when my husband told me he saw a Facebook post saying Keith was in a hospital. I had to check it out myself and was even more concerned.

Keith’s symptoms suggested a heart problem; tests were being done to see if he needed surgery.

Here’s what he wrote on January 27 from his hospital room

Dear family and friends! Well… unfortunately, it seems like I’m not going to be able to go to Africa at this time. It looks like I’m going to need to go in for my 28,000 mile “radiator flush”!

For the past two weeks, I have been having some health challenges. I have written them off, or marked them up as wear and tear from the journey. I was sent to the emergency room two weeks ago while I was speaking in New York.

Things seemed like they were improving, but everything took a sharp turn for the worse a few nights ago. I’m in the heart hospital.


KW, Facebook January 27, 2024

And Keith was right. He isn’t going to Africa anytime soon. Again, here’s the story in Keith’s words.

Unfortunately, we didn’t get the news we had hoped for. They performed a heart cath on me and found 100% blockage in my “widowmaker” and 80% in another. They weren’t able to put in a stent. So, I have to have open heart surgery (double bypass) this week….

KW, Facebook, January 30, 2024


If you think Keith was feeling sorry for himself, or was mad at God, or thought God was mad at him-well, you don’t know Keith.

I’ve always felt that perspective is such a gift! It seems to always put everything into perspective! Truly, things can always be better… But they can always be so much worse!

In the big picture, I’m doing great! I’m so much healthier than many other people in our world! I’m probably much healthier than most of the other people in this hospital! I’m probably much healthier than many people on my floor here in the hospital!

Also, I have my fairytale princess by my side … so, so many people have no one, and are so very lonely!

And most of all, I have Jesus! I have hope! I have peace! I have joy! He is loving. He is good. He is kind. And, He is with me always! My days, my breaths, my heartbeats are in His hands! My life is in His hands! He’s so very worthy!

A New Cross and Total Peace

Keith and Nicole, his fairy tale princess


As Keith was waiting to go into surgery, he wrote these words

I’m at total peace! If I close my eyes today and open them and see Jesus, I win! If I close my eyes today and open them and see my fairytale princess, I win! It’s a win-win!

My prayer is that when they open me up, they will either wonder why they had to operate because I’m totally healed, or when they open my heart that they will see Jesus smiling back at them!🕊❤️‍🔥‼️

New Heart Day

The next day, we were relieved to read an update, this time from Nicole, his fairy tale princess wife (that’s what he calls her.)

My Prince is recovering and he just took his very first lap around the unit. (Many more laps to come). 😀

He’s sitting up, greeting everyone that comes into the room with a smile, and telling them about Jesus. Thank you so much for walking with us on this journey!! So appreciate your outpouring of love and prayers.

#February1NewHeartDay❤️

Keith’s “new” Heart

About a week later Keith left the hospital, returning home where he and Nicole took a walk in their neighborhood. Back to posting online himself, Keith revealed that before his surgery, he had “flatlined” and had to be resuscitated, and promised to write more about his journey later.

I’ll write more on the journey in the days to come. Today, I just want to say thank you from the bottom of my heart! With God’s help, I’m home and doing well.

A few days before his heart surgery, Keith shared this scripture on Facebook.

”Keep and guard your heart with all vigilance and above all that you guard, for out of it flow the springs of life.“
