AED Advantage recently attended the 2018 Oil Sands Tradeshow in Fort MacMurray, and among the many people we were fortunate to meet, Mark McGregor is a cardiac arrest survivor. He shared his incredible story with us.

The following is an excerpt from the Reader's Digest article from March 1999 where Mark's story first appeared.


This Machine is a Lifesaver

So why isn’t it widely available?

By Angela Pirisi

Ross Cooper, 71, of Owen Sound, Ont., had just got into bed on the evening of February 20, 1998, when he fell back, knocked his head on the headboard and collapsed. His wife, Louise, 73, heard the thump but assumed her husband had merely bumped his hand while turning over in bed. When she asked him a question, though, he didn’t respond. She said something else to him; still no response. Finally turning on the light, she was horrified to see his mouth gaping, his face purple, his eyes shut.

Not sure what was happening, she phoned her granddaughter, Mavis Tolhurst, a registered nurse, who lived across the street. Tolhurst and her husband arrived within a minute. As he dialed 9-1-1, Mavis started performing cardiopulmonary resuscitation (CPR). Volunteer firefighters arrived two minutes later and continued to administer CPR to Cooper, whose lips had now turned blue.

Cooper’s heart had been seized by the chaotic rhythm called ventricular fibrillation (VF), and CPR alone could not jump-start it. His only hope was the process called defibrillation – a brief electrical shock that overpowers the VF rhythm so the heart can resume its natural contractions. But by the time paramedics carrying a defibrillator reached the couple’s home, it had been more than twen minutes since Cooper’s collapse. Severe brain damage had set in, despite the fact that the emergency crew managed to restart his heart.

Four days later his family made the wrenching decision to take the brain-dead Cooper off the hospital ventilator. He died shortly after.

A great majority of cardiac-arrest victims die before help can reach them. But these deaths are not inevitable. Dr. Michael Shuster, chairman of the emergency cardiac-care coalition for the Heart and Stroke Foundation in Banff, Alta., thinks more lives could be saved. “For most cardiac-arrest victims, using defibrillation early enough greatly increases one’s chances of survival.”

Time is critical: Many cardiac arrests become fatal four to seven minutes after VF begins. so early defibrillation is the single most crucial factor. Every minute that passes before returning the heart to its normal rhythm decreases the chance of survival by ten percent; after just four minutes without defibrillation, only about 60 percent of victims survive. After ten minutes, few do.

But in rural areas as well as in traffic-congested cities, emergency medical technicians (EMTs) equipped with defibrillators usually arrive too late. For years the cardiac arrest survival rate in cities like Hamilton, for example, was around four percent. Nationwide, it still averages less than ten percent.

But a safe and effective technology exists that could improve these odds dramatically. It is the automatic external defibrillator (AED), a small computerized, battery-operated device, which can  be as small as a book and weigh as little as two kilograms.

An AED is nearly foolproof to operate. And its cost – about $5,000 and dropping – is reasonable considering its lifesaving ability.

In Hamilton, AEDs have transformed emergency care of cardiac-arrest patients. In 1988 Shuster, then medical director of the McMaster paramedic program, along with Brent Browett, program co-ordinator of of paramedic services for the Hamilton Health Science Corporation, noticed that the fire trucks usually reached cardiac-arrest victims four to six minutes before paramedics did. As trained “first responders,” firefighters gave CPR but had no way of defibrillating victims, who often died.

“Why not equip trucks with defibrillators and train firefighters to use them?” the pair suggested.

Ten years later Hamilton boasts one of the highest cardiac-arrest survival rates in North America – 19 percent. Typical of recent years is 1996, when firefighters defibrillated 63 people, 42 of them with pulses successfully restored upon arrival at hospital.

The firefighters’ lifesaving efficiency was tested last April 19 at a Hamilton hockey rink. Financial consultant Mark McGregor, 36, thought things seemed a bit blurry when he first stepped onto the ice for a local hockey tournament, but he ignored it. Then after playing just one shift, he sat on the bench feeling dizzy, as though he was suffocating. “I’m not feeling quite right,” he said to a teammate.

Two seconds later his body went numb and he keeled over, hitting his forehead on the rail in his fall. His stunned teammates immediately sent an emergency hand signal across the ice, telling someone to dial 9-1-1. It was 4:41 p.m.

Firefighters Dave MacDonald, Bill Kreidl and two other colleagues arrived at 4:42. McGregor was quickly deemed VSA (vital signs absent) and the crew began administering oxygen and CPR. As MacDonald cut through the bulky hockey equipment, Kreidl pressed the AED pads firmly onto McGregor’s chest. The computer’s “voice” announced: “Analyzing heart rhythm. Do not touch the patient.”

Within seconds the recorded voice cautioned: “Shock advised. Stay clear of the patient.” Then the machine intoned the message, “Deliver shock now.” Kreidl stabbed the button. “Shock delivered,” the computer proclaimed. It was 4:44. Less than five minutes had elapsed since the 9-1-1 call.

Mark McGregor was released from the hospital three weeks later. He credits the AED with saving his life: “Thanks to the AED, my two-year-old daughter still has a father around to watch her grow.”

Hamilton’s experience has demonstrated that non-medical professionals equipped with AEDs and proper training can save many cardiac-arrest victims. Following that city’s lead, other fire departments nationwide have embraced the use of AEDs.

Calgary created an AED committee in 1994 and has since undertaken to train and equip all its firefighters and EMTs. The city now boasts an exceptional survival rate of 23 percent. The committee has also helped spearhead a public-access program that’s putting AEDs in public spaces and in the trained hands of security guards, building managers and lifeguards until, ideally, there’s on of these lifesaving devices on every city block.

Last spring the South Dumfries Fire Department in St. George, Ont., equipped its volunteer crew with an AED, using a community fund-raiser called Operation Heart Start to raise $30,000 to buy the machine and pay for training and equipment.

Likewise, AEDs have taken hold in places such as Brandon, Man., and Rainbow Haven Beach – just outside Halifax – which boasts the first beach AED program in Canada. The two-year old program operates during the high-activity summer months, when cardiac events at the water’s edge are more likely.

How can AEDs make a difference? In Ontario on April Fool’s Day, 1997, Brant County Ambulance paramedics were trained to operate a newly purchased AED. Just three weeks later, they used it to save the life of 65-year-old retired engineering technologist John Manners of Brantford, who had suffered a heart attack and gone into cardiac arrest.

Saskatoon continues to be a leader in lives saved with the help of AEDs. Medavie Health Services West had an award ceremony earlier this year to honour some saviours and survivors.

“Patel, a supervisor at the Shaw Centre, said through the team effort of the five employees — thanks to extensive emergency medical training from the city — they were able to able to use the AED and chest compressions to restart the man’s heart within the six minutes it took for paramedics to arrive on scene.” (Excerpt from story)

Michael Isely was saved thanks to an off-duty paramedic friend and his father, as they were able to use chest compressions and an AED to bring him back.

The AED Advantage Heart Starters team participated once again in the annual Heart and Stroke Big Bike ride! We were proud to raise money for the Heart and Stroke's mission to significantly improve the health of all Canadians by investing in life-saving research; advocating for healthier communities; and providing support for survivors of heart disease and stroke as well as their families and caregivers.

It was a cool morning but once the bike got moving it sure warmed everyone up! We had a great time, and want to thank the Heart and Stroke for having us once again, all of our riders that came out to help us pedal, and a special thanks to our very own survivors Rodney and Vincent for making it out! Their presence makes the work we do have so much more meaning and pride.

Read Rodney's Story and Vincent's Story if you haven't yet, as they both have made it through an incredible experience, and we are so glad to have them around!

And finally some pictures of the fun we had!

Vincent's Story

[This was written April, 2017.]

"My name is Vincent Bitusus, I am 38 years old.

On Saturday December 3, 2016, the Filipino Basketball League had their season opener tournament at Holy Cross High School. At 2 pm my team played their first game. I am a forward on the team. Three minutes into the game, I was looking for my opponent and my vision started to turn blurry, that is the last thing I remember.

My friends have told me what happened after my last memory. I collapsed on the court and turned blue, my body went rigid, I was foaming at the mouth and my eyes rolled back in my head. Thankfully there were many spectators at the tournament and some of them were trained in 1st aid and CPR as well as AED. Three people assessed my condition, I was not breathing and had no pulse. They started CPR, and did four rounds of breaths and compressions but they could not revive me. The lady leading the rescuers was an off duty nurse, and she called for an AED, thankfully the school had one. They hooked up the AED and the machine instructed them to administer a shock and then another. After the second shock, people said my color came back and I opened my eyes and I began to question what had happened.

An ambulance had been called and Paramedics arrived after I woke up. I was transported to RUH and after four days and many tests, an angiogram found that my main coronary artery was 99% blocked. A stent was put into my heart and the recovery process began.

Thank God for AEDs they saved my life."

John's Story

[This is written August 2nd, 2014.]

"Canada Day started out like many other vacations spent in the city, with me volunteering an hour at a community booth. I was a bike valet from 11:00 a.m. to noon, watching peoples’ bikes for them. Soon after noon I rode off to find a few minutes of adventure before planning to return home to my girlfriend’s, where we were taking the kids over to a local park to meet another friend and her kids at 1:30.

I found the SaskPower propaganda booth with a game. It was a stationary bike where you could see how much power you could produce on it.

And that’s one way that SaskPower has tried to kill me ;-). As I finished at the top of the leaderboard, and biked off into the distance, I soon was collapsed on a bench near the band stand in Wascana Park. A crowd gathered, and two police officers came up to find me without a pulse and my bike helmet still on. They began CPR and called for a pair of EMTs on bikes who were on the other side of the park.

The EMTs arrived about 10 minutes later and after shocking me twice, my heart was beating again. About 40 minutes and a $325 ambulance ride later, I was in the Emergency Room of the General Hospital. I was scoring a 5 out of 15 on the Glasgow Coma scale in some regard, 8 in others. A 5 can mean that I could need to be tube fed, while 15 would be normal. So I was put onto a cooling blanket and given an immobilizing drug to cool my body down to just 32 degrees Celsius.

My first-hand memories from the next three or four days are few and I barely recognize them as my own experience. A tube coming out of my body that wasn’t there when I woke up and started remembering is one clue. In my defence, I was sedated and intubated for the first two days. Pretty extreme considering I’d not spent a night in hospital since I was born.

I then had an MRI, and various radiating scans on my head and elsewhere to check I was all there. In the coming days I managed to impress the professionals enough for them to let me out in the wild again (but not after tagging me first).

And here I am. Alive. Surprised that I died, and came back to life. Thankful for another chance, whatever that means."

AEDs. What are they?

Q: What does AED stand for?

A: AED stands for “Automated External Defibrillator.” AEDs are used to deliver lifesaving electroshock therapy to someone who is suffering a cardiac arrest. They are designed to be as straight forward and easy to use as possible, to allow non-medically trained people the best chance possible to save a life.

Q: How does it work?

A: Every AED has two pads (called electrodes) connected to the machine that must be placed on a patient’s chest. The AED then analyzes the patient’s heart rhythm to determine if a shock will be needed to save the patient. If it is needed, the AED will instruct the rescuer through the steps necessary to save the person’s life.

Q: What is SCA?

A: SCA stands for “Sudden Cardiac Arrest”. SCA happens when the electrical signals in the heart go into disarray, causing a lack of blood to be pumped to the brain, and the victim to go unconscious. This condition is called “Ventricular Fibrulation”. Over 35,000 deaths per year occur from SCA in Canada. When this happens, the victim only has minutes to be saved. Only defibrillation can stop VF.

Q: What is the difference between SCA and a Heart Attack?

A: While SCA is an electrical problem with the heart, a Heart Attack happens when there is blockage in the aorta. While sometimes difficult to tell the difference, a Heart Attack victim will often maintain consciousness, whereas an SCA victim will most often be unconscious.

More Info About Sudden Cardiac Arrest (SCA)

  • SCA is a condition where the electrical system of the heart short circuits, causing an abnormal rhythm known as ventricular fibrillation.
  • A victim of sudden cardiac arrest is unconscious, is not breathing and has no pulse. When the heart stops beating there is a lack of oxygen to the brain and a patient will die unless emergency treatment is given immediately. Sudden cardiac arrest is not the same as a heart attack. A heart attack occurs when a blocked artery results in damage to the heart muscle by keeping blood and oxygen flowing to it. A heart attack can lead to a cardiac arrest.
  • Sudden Cardiac Arrest is one of the leading causes of death around the world.
  • It strikes 40,000 people in Canada every year.
  • Only 5 – 10% of victims survive.
  • Every minute of every day SCA claims a victim.
  • Victims of all ages have been documented including teens, athletes, young and older adults.
  • The time between the onset of cardiac arrest and defibrillation is the major determinant for success in a resuscitation attempt. While cardiopulmonary resuscitation (CPR) can support circulation and ventilation in a victim of cardiac arrest for a short period of time, it is unlikely to convert ventricular fibrillation (VF) to a normal heart rhythm.

Where should you expect to find AEDs?

Q: How do I know if I should get an AED?

A: Anyone can fall victim to SCA at any time, regardless of age, gender or lifestyle (although the risk percentage does increase depending on these factors). AEDs are being placed anywhere there are gatherings of people; in the office or factory, events centres, family cottages, golf courses, condo buildings, etc. The ideal placement of an AED is that no matter where someone has SCA, an AED can be retrieved and brought to the victim in 3 minutes or less. Buildings that contain AEDs usually will have a sticker indicating an AED inside, along with some signage directing to where the AED is kept, on a wall, in a cabinet, in an office, etc.

Q: How do I determine which AED is the best choice for my business/organization/home?

A: While all AEDs function very similarily, there are a few things to look for. Public Access AEDs should be as easy to use as possible for non-medically trained people. Avoid AEDs that may be too confusing  for the lay-rescuer, too many visual, audio instructions, too many details on the electrodes, etc. Choosing an AED with escalating energy is also important, as no two body types are the same, and more energy may be needed for more difficult to defibrillate patients.

Q: What does the Heart & Stroke Foundation say about AEDs?

A: The Heart & Stroke is a strong advocate for having publicly accessible defibrillators everywhere there are gatherings of people. You can view the entire Heart & Stroke position on AEDs in the link below. There are many great resources on the Heart & Stroke website!

Heart & Stroke Position Statement on Public Access To Automated External Defibrillators (AEDs)

How difficult is it to use an AED?

Q: Can I shock someone with an AED if they don’t need it?

A: AEDs are designed to be extremely safe to use. AEDs will only deliver a shock when the electrodes have been properly attached to a patient, and the AED reads that the patient has a specific, shockable rhythm. 

Q: Is it safe to use an AED on a child?

A: All AEDs have some form of infant/child specific electrodes or settings, for a patient under 8 years of age, or approximately 55 lbs. Even if the AED does not have a set of infant/child pads nearby, it is advised to use the adult electrodes, as any action is better than none. The electrodes are placed on the front and back of the child, rather than front and side as depicted on the electrodes.

Q: Are there any legal implications for using an AED?

A: In Canada there are Provincial and Federal Good Samaritan Laws, stating that as long as the rescuer acted in good faith attempting to save a victim from death, they are protected. Recently, provinces have begun to use language specifically referencing AEDs.

Is there any maintenance for an AED?

Q: How often do I need to change the battery on my AED

A: All AEDs have some variation of a lithium battery pack that must be replaced anywhere from every 2-5 years. The battery may need to be replaced more frequently if the AED is used. The AED will inform you when the battery pak needs to be replaced, however it is important to record when the battery was installed so you can plan for an approximate replacement date.

Our Free AED Registry System can assist you with tracking these expiry dates.

Q: Do the electrodes need to be replaced?

A: The electrode pads for your AED should be replaced approx. every 2 years. The pads are made with a water-based gel, which does eventually dry up over time, so it is important to always have current electrode pads with your AED.
