Detroit Heart · AED, the automated external defibrillator

A box on the wall. A life in your hands.

When someone collapses and isn’t breathing normally, you have minutes. An AED talks you through every step and only shocks if it’s needed. The catch: almost nobody in Detroit knows where they are. We’re changing that, together with you.

Every minute counts

How much time do you have?

When the heart stops and nobody starts chest compressions or uses an AED, the chance of survival drops by 7–10 percent with every passing minute. After ten minutes, resuscitation rarely succeeds.2

A widely cited 1993 model puts the drop at about 5.5 percentage points per minute with no treatment at all. Sources differ on the exact number, never on the direction: every minute counts.3

Every minute that passes cuts the chance of survival by 7–10 percent if nobody starts CPR or uses an AED. After ten minutes, resuscitation rarely succeeds.

  1. 3Within this many minutes, casino security officers gave the first shock to the patients of whom 74 percent survived.4
  2. 7.6The median time for EMS to arrive in the U.S. in 2025, in minutes. Until then, it’s up to you.5
  3. 10Ten minutes without CPR or a shock: by then, resuscitation rarely succeeds.2

What the research says

Numbers that mean lives

Thirty years of U.S. research says the same thing: when an AED is nearby and someone uses it, far more people survive. Every number links to its source.

  • 74%In Nevada casinos, security officers used AEDs. Of those who collapsed in front of witnesses and got the first shock within three minutes, 74 percent left the hospital alive. Of those shocked later, 49 percent.4
  • 2×In a large U.S. and Canadian trial, where lay volunteers learned CPR plus AED use, twice as many people survived cardiac arrest (30 instead of 15) as where they learned CPR only. Not one inappropriate shock was given.6
  • 66.5%That’s how many patients with a shockable rhythm who collapsed in public survived when a bystander’s AED gave the first shock. When EMS shocked first: 43 percent.7
  • 70%According to the American Heart Association, about 70 percent of children survive cardiac arrest in schools with AEDs: seven times the overall survival rate for children.8
  • 90 sThat’s how long untrained sixth-graders took to deliver a shock with an AED in a simulated cardiac arrest. Trained paramedics took 67 seconds.9
  • 10.5%That’s how many people survived an out-of-hospital cardiac arrest in the U.S. in 2025: 20.9 percent in public places, only 8.9 at home. A nearby AED and a brave bystander change the odds.10

What’s in the box?

A smart machine that talks you through a rescue

An AED (automated external defibrillator) is a portable, battery-powered device. Through two pads stuck on the chest, it reads the heart’s rhythm. If the heart is quivering chaotically instead of pumping, one shock can reset it to a normal rhythm. It usually lives in a wall cabinet with a green sign: in office buildings, airports, stadiums, schools and gyms.

  • It talks to youThe moment you turn it on, it says every step out loud, and many models show pictures too.
  • It only shocks when neededIts built-in computer analyzes the heart rhythm and only delivers a shock if one is needed. In a large trial, not a single unnecessary shock was given.11,6
  • Child’s play, literallyIn a U.S. study, untrained sixth-graders delivered a shock in 90 seconds; trained paramedics took 67. Every one of them put the pads in the right place.9

Look for this sign: a white heart with a lightning bolt on green. When you see it, remember it, and report it to us.

In an emergency

What do you do? Four steps anyone can take

If someone collapses, doesn’t respond and isn’t breathing normally (or is only gasping), don’t wait. Every second counts.

  1. 1

    Call 911

    Put the phone on speaker and set it down next to you: the dispatcher will guide you. If anyone else is around, send them for an AED.

  2. 2

    Push on the chest

    Two hands, center of the chest, hard and fast: 100 to 120 times a minute, about 2 inches deep. Don’t stop until help arrives.12,13

  3. 3

    Turn on the AED

    Open the lid or press the power button. From there, it talks to you and tells you what comes next.

  4. 4

    Stick on the pads and listen

    The pads go on the bare chest; the picture shows where. Nobody touches the person during the analysis or the shock. Then keep pushing until paramedics take over.

Got the rhythm?

Chest compressions should run at 100–120 a minute. Tap the red button at that pace and we’ll tell you if you’ve got it. Turn on the metronome if it helps.12

The rhythm trainer needs JavaScript. The key: 100–120 pushes a minute.

The heart of Detroit

More than 500 AEDs. But where?

On August 27, 2024, Detroit became the largest municipality to earn the HEARTSafe Community designation. According to the city, more than 500 AEDs are registered across Detroit, and more than 100,000 people have been trained in hands-only CPR and AED use.14,15

Detroit has already proven it can change. In six months of 2002, just one of 471 out-of-hospital cardiac arrest patients survived. In 2024, 25 percent of patients who collapsed in front of bystanders with a shockable rhythm survived, and 39.5 percent when a bystander gave CPR or used an AED. Bystanders started CPR in 13 percent of cases in 2015 and in 36 percent in 2024.16,17

But that list lives in a separate mobile app’s registry; you can’t browse it on an open map. In September 2026 we combed the open web and found sourced AEDs at just seven places inside Detroit’s city limits, twelve devices in all. OpenStreetMap, the open world map, had not a single AED marked in Detroit.18

The visitor guides for Comerica Park, Little Caesars Arena and the Fox Theatre mention first-aid stations, but no AED. There may well be one. But in an emergency the question isn’t whether it exists; it’s whether you know where it is.19,20,21

Research shows that people who collapse in low-income, mostly Black U.S. neighborhoods are about half as likely to get CPR from bystanders as people in high-income, mostly White ones. In a 2026 Wayne State study, 84.6 percent of Detroit cardiac arrest patients who received CPR were Black. Here, it matters even more that everyone knows where the nearest AED is.22,23

Philadelphia has shown what a city gains when it searches together. A 2011 survey found no AED in 88 percent of publicly accessible buildings. Then in a 2012 crowdsourcing contest, more than 300 people photographed and mapped over 1,500 AEDs in 800 buildings in eight weeks. Detroit can do it too.24,25

Myths

What’s holding you back?

What if I get it wrong and get sued?

In Michigan, the law protects you. Anyone who voluntarily and in good faith gives CPR or uses an AED in an emergency is not civilly liable, except for gross negligence or willful misconduct. The protection also covers whoever owns the building where the AED hangs.26

Can I hurt someone with it?

The AED makes the shock decision itself: it analyzes the heart rhythm and only shocks if it’s needed. In the big public-access trial, not one inappropriate shock was given. The worst thing you can do is nothing.11,6

I’ve never been trained.

You don’t need a course, though it helps. Untrained sixth-graders delivered a shock in 90 seconds; paramedics took 67. At Chicago’s airports, 6 of 11 resuscitated patients were saved by rescuers with no AED training. The machine says every step, and the 911 dispatcher helps you throughout.9,27,11

What if the person is a woman?

Help just the same. In public, women get bystander CPR less often than men (39 percent versus 45), and less often get an AED too. The pads go on bare skin: a life matters more than any awkwardness.28,5

Do schools need one too?

Yes. According to the AHA, about 70 percent of children survive cardiac arrest in schools with AEDs. A 2024 Michigan law requires every school to have a cardiac emergency response plan from the 2025–2026 school year, with clearly marked AEDs that aren’t locked away. The catch: it’s only mandatory if the state pays for it, and as of February 2026 it hadn’t.8,29,30

When all of America was watching

Damar Hamlin’s heart started again. In front of a whole stadium.

On January 2, 2023, during a Monday night game against the Cincinnati Bengals, the Buffalo Bills’ 24-year-old safety took a hit to the chest and collapsed: his heart had stopped. Medical staff gave him CPR on the field and used an AED. His heartbeat was restored before he left the field.31

Since then, Hamlin has fought for more people to learn CPR and for AEDs in more places. On April 27, 2024, during the NFL Draft in Detroit, he stood beside Governor Gretchen Whitmer as she signed Michigan’s school AED and CPR bills, and donated 50 AEDs to Michigan schools. The lesson is simple: luck didn’t save him. Someone nearby who knew what to do did, and a machine that was there.32
