The History of Defibrillation, Defibrillators and Portable AEDs

From dogs to tablespoons to Zolls, AEDs have come a long way

As you can tell, we’re on a bit of a history kick here at Cardio Partners and AED.com! This week we’re dialing the way-back machine to 1899 to learn more about the origins of defibrillation and the birth of AEDs. To learn more about the History of CPR, check out last week’s post!

1899: The Dog Days of Defibrillation

Defibrillation was discovered at the University of Geneva in 1899 by physiologists Jean-Louis Prevost and Frédéric Batelli. In the course of their research on ventricular fibrillation — a condition that occurs when the heart beats with rapid and erratic electrical impulses and causes the chambers in the heart to quiver ineffectively — they discovered that they could induce fibrillation in dogs and then, with an even higher jolt, defibrillate by applying high-current shocks directly to the surface of the heart.

Admittedly, this was a pretty significant discovery, but because they used a very high voltage, the poor pup’s heart was ultimately incapacitated and subsequent defibrillation theories focused more on the harmful effects of the procedure rather than the potential positive, life-saving effects we’re all familiar with today (National Center for Biotechnology Information).

1933: Self-Starter for Dead Man’s Heart

A generation later, in October of 1933, Popular Mechanics ran an article about Dr. Albert S. Hyman’s promising new invention, Hyman’s Otor.

The device was essentially a “hollow steel needle, through which a carefully insulated wire runs to the open point. Both the needle itself and its central wire are connected to the terminals of a light, spring-driven generator, provided with a current-interrupting device. This mechanism can be adjusted to give electrical impulses with the frequency of the heart-beat from infancy to old age. When the physician faces a case of heart stoppage, he inserts the needle between the first and second ribs into the right auricle of the heart, and starts the generator at the required frequency” (Source: Modern Mechanix).

The device was tested on animals and revived 14 out of 43 victims of cardiac arrest (Science Museum, London). Even though the device received positive press coverage, it was perceived as interfering with natural events and was not accepted by the medical community.

1947: What a Difference a Decade Makes…and Spoons

If you’ve been wondering where the tablespoons come in, you’re about to find out! The first successful defibrillation was reported by an American surgeon, Dr. Claude S. Beck, in 1947.

His patient, a 14-year-old boy, “tolerated the surgery well but went into cardiac arrest during closure” (Resuscitation Journal). Using a combination of direct cardiac massage, drugs, and a shock delivered by what appears to be gauze-covered spoons, the boy was successfully resuscitated (Case Western Reserve University).

1950: Zoll Begins Working on an External Pacemaker

Yes, the Zoll that we all know and love was founded by a Harvard cardiologist and an AED pioneer. “In 1952, Dr. Zoll and a team of other doctors in Boston applied electric charges externally to the chest to resuscitate two patients whose hearts had stopped. The first patient lived only 20 minutes. The second patient survived for 11 months, after 52 hours of electrical stimulation” (New York Times).

1965: Defibrillators Go Mobile

In 1965, a professor from Northern Ireland, Frank Pantridge, invented the world’s first portable defibrillator. Known as  “the father of emergency medicine,” Pantridge’s device relied on a car battery for current. The 150 pound device was installed in an ambulance and was first used in 1966 (BBC News).

1972: LBJ is Saved Today

In 1972, when President Lyndon B. Johnson suffered a massive heart attack at his daughter’s Virginia home, he was revived by a portable defibrillator.

“Dr. Richard S. Crampton of the University of Virginia Medical School in Charlottesville, who rushed a mobile coronary care unit to former President Lyndon B. Johnson…said in an interview: ‘It has tremendous potential application. Conceptually, this ought to be on every plane, train, bus, at stations and at airports, in case someone suddenly collapses. It’s like a fire extinguisher; you just hang it on the wall and you go put out the fire, which happens to be ventricular fibrillation’” (New York Times).

2018: Where We Are With AEDs Now

Today, portable AEDs are so easy to use that many states require their placement in schools, sports arenas, airports, health clubs, casinos, and other public places. Portable AEDs are also available for home use.

Unlike professor Pantridge’s “portable” defibrillator, modern AEDs typically weigh approximately 3 pounds and are fully automated.

Which Automated External Defibrillator (AED) is Right for You?

AED Buyer’s Guide: 5 Things to Consider When Choosing an AED

Why are AEDs so Important?

So you’ve decided to purchase an AED. Good for you! The statistics surrounding sudden cardiac arrest (SCA) are sobering, but your decision to buy an Automated External Defibrillator for your home or workplace may save a life. Here at Cardio Partners and AED.com, we’re ready to help you find the one that’s best for you or your organization!

Did you know that more than 350,000 Americans suffer from cardiac arrest each year? Approximately 10,000 of these occur in the workplace (OSHA) and a staggering 70% of out-of-hospital cardiac arrests occur at home. At least 20,000 lives could be saved annually by prompt use of AEDs (American Heart Association).

In other words, if you are called on to perform CPR or to administer a shock from an AED, you’re likely working to save the life of someone you know and love. The American Heart Association (AHA) also notes that communities with AED programs, which include comprehensive CPR and AED training, have achieved survival rates of 40% or higher for cardiac arrest victims.

AEDs save lives by restoring normal heart rhythms in individuals who suffer sudden cardiac arrest.

An AED is a small, portable and user-friendly electronic device that can automatically diagnose and respond to life-threatening heart rhythms. Most AEDs provide simple, easy-to-follow audio and visual instructions that bystanders can quickly comprehend and apply. Some AEDs advise the user when to administer the shock, while other AEDs may automatically apply a shock if the heart is arrhythmic.

So what are you waiting for? Here’s everything you need to know about finding the right AED for your home or business.

1) Price

As with any technology, prices for AEDs vary widely. When considering price, think about your needs, your training, and how often and under what conditions your AED is likely to be used.

A recertified Cardiac Science Powerheart G3 comes in at a modest $595 while a new Zoll AED Pro is priced at $2895. Professionals rescuers can appreciate the Zoll’s See-Thru CPR® feature, which allows them to see a patient’s underlying cardiac rhythm during resuscitation efforts. This feature enables more consistent, interruption-free compressions.

2) Pads

When it comes to AED pads, one-size-fits-all isn’t an option. Broadly speaking, there are two types of AED pads: Adult and pediatric. Consider the population you’re most likely to use your AED on and purchase your equipment accordingly. If, for example, your AED is placed on a shop floor or in a retirement community, it’s unlikely you’ll need pediatric pads! If your AED is going to be placed in a school setting, however, you may want to consider a school AED package that includes both adult and pediatric pads.

3) Batteries

Pretty much every AED manufacturer has a unique battery that’s patented for the exclusive use in their machines. Although most AED batteries are non-rechargeable, devices with rechargeable batteries are also available. Some AEDs, like the Zoll AED Plus, even use standard consumer 123 lithium batteries!

Once again, how you plan on using your device should determine whether you select a unit with a rechargeable battery or one with a non-rechargeable battery. Bottom line: If you’re a professional who regularly uses an AED, a rechargeable battery may be right for you. CPR and AED instructors may also benefit from rechargeable training units such as the Defibtech Lifeline AED Trainer. However, If your AED is rarely used, a low-maintenance non-rechargeable battery (with a longer lifespan) may be the best bet.

Remember, a well-charged and up-to-date AED battery is essential to the proper functioning of your device! If you are purchasing an AED for your home or office, we highly recommend that you to invest in an AED Compliance Management Program.

4) IP Rating

Every AED has an IP code. This “International Protection Rating” or “Ingress Protection Rating” is a code which classifies the level of protection an electrical device (like an AED) provides against liquid and dust. If you’re shopping for a poolside AED, look for a high IP rating and consider a waterproof Pelican Case.

5) Size

If you’re planning on mounting your AED cabinet to the wall and forgetting about it until your compliance management program sends you a maintenance reminder, then size doesn’t matter. However, if your AED follows you wherever your team travels, then you’ll want to find a light and compact unit, like the Philips HeartStart OnSite AED.

Don’t Press Your Luck by Waiting – Be A Lifesaver!

You witness a co-worker suddenly collapse and they are unresponsive. What is your course of action? 
Most people believe that the best thing you can do is call 911 and wait for medical professionals to arrive. Unfortunately, victims of sudden cardiac arrest (SCA) have a less than 10% chance of survival on average in the United States.

The first step in any emergency situation is always to call 911, but to give your co-worker, friend, or loved one the best chance of survival—you should immediately begin CPR and use an AED.

As each minute passes, the SCA victim is 10% less likely to survive without CPR or defibrillation with an AED. Average EMS response time in many metro areas is 7-12 minutes, with rural areas taking much longer. Simply put, waiting for EMS to arrive can be detrimental to the victim.

The heart’s dangerous rhythm during cardiac arrest can only be reversed with defibrillation. Using an AED, a lifesaving tool designed for ANYONE to operate, provides defibrillation therapy. AEDs will analyze the patient and ONLY provide a shock if the person needs one. You CANNOT accidentally shock a person using an AED.

Already have AEDs available in your organization or workplace?

Remember, don’t press your luck by ignoring the AED. Implement an AED Management Program so your team is always rescue ready!

• Assign someone to be in charge of maintaining your AED(s)

• Train designated responders at your facility who can confidently respond with highly-effective CPR and quick use of the AED

• Place AEDs in accessible locations with the ability to retrieve an AED and return to patient within 90 seconds

• Make sure the battery and electrode pads are checked regularly (Battery failure is the #1 cause of AEDs not working properly during a rescue)

• Replace expired pads or dead batteries promptly
