Fun Fact: mouth-to-mouth resuscitation is three centuries old! Who knew? Before we dive into the fascinating history of CPR, however, we’re going to take a moment or two to talk about cardiac arrest, how CPR works, and how something that was first analyzed in a medical publication in 1792 has evolved into modern-day CPR.

A Few Words about Sudden Cardiac Arrest

Sudden cardiac arrest (SCA) can happen at any time. In many cases, victims may appear perfectly healthy and may not have any known pre-existing heart conditions. AED and CPR advocate Rob Seymour, who we profiled in March, is a perfect example!

Unlike a heart attack, which is caused by a blockage in an artery or vein, SCA occurs when the electrical system of the heart stops functioning. While heart attacks are often preceded by some pretty clear symptoms, SCA rarely is. If you’d like to learn more about the difference between a heart attack and SCA and their symptoms, you’re in luck — we covered that topic back in March!  

According to the American Heart Association, approximately 350,000 people suffered cardiac arrest outside of a hospital in 2016. An additional 209,000 cardiac arrests occurred in a hospital setting.

People who experience cardiac arrest outside of a hospital have about a 12% chance of survival. While that’s a pretty dismal statistic, the good news is that the survival rate has been increasing over the past several years. Furthermore, the chances of survival are doubled or even tripled if the victim receives CPR from a bystander—even one with no prior medical training! If that’s not enough, check out our post, 10 Reasons to Learn CPR.

The key to survival for victims of cardiac arrest is often receiving CPR immediately.

How CPR Works

CPR, or cardiopulmonary resuscitation, is an easy-to-learn first aid technique that can keep the victims of a sudden cardiac arrest (SCA) or other medical emergency alive until medical professionals can take over. Chest compressions and rescue breathing work together to keep oxygen flowing in and out of the lungs and to maintain the flow of oxygenated blood throughout the entire body.

When rescue breaths are used, the rescuer’s exhaled breath provides the victim with additional oxygen. Although we exhale carbon dioxide, there’s enough oxygen in every exhaled breath (approximately 16%) to help an SCA victim (University of Washington).

The History of CPR

1700s

In 1740, The Paris Academy of Sciences officially recommends mouth-to-mouth resuscitation for drowning victims. And 17 years later, The Society for the Recovery of Drowned Persons becomes the first organized effort to deal with sudden and unexpected death.

Dr. James Curry publishes “Popular Observations on Apparent Death from Drowning, Suffocation, Etc., with an Account of the Means to be Employed for Recovery” in 1792.

1800s

In 1892 German doctor Friedrich Maass publishes “Resuscitation Technique Following Cardiac Death after Inhalation of Chloroform” in the Berlin Clinical Weekly.

1900s

At the turn of the century, an American surgeon, Dr. George Crile, reports the first successful use of external chest compressions in human resuscitation.

In 1954 Dr. James Elam is the first to prove that expired air was sufficient to maintain adequate oxygenation. Two years later, Elam and Dr. Peter Safar are able to prove the efficacy of CPR and mouth-to-mouth resuscitation.

1960s

The American Heart Association starts a program to acquaint physicians with closed-chest cardiac resuscitation. This program becomes the forerunner of CPR training for the general public.

Cardiologist Leonard Scherlis starts the American Heart Association’s CPR Committee in 1963, and later that same year, the American Heart Association formally endorses CPR.

1970s

In 1972, Leonard Cobb holds the world’s first mass citizen training in CPR in Seattle, Washington called Medic 2. He helps train over 100,000 people during the first two years of the program.

1980s

Now considered common practice by 911 operators, a program to provide telephone instructions for CPR begins in King County, Washington.

1990s

Early Public Access Defibrillation (PAD) programs are developed to provide training and resources to the public to improve bystander assistance rates and to increase the successful resuscitation of cardiac arrest victims.

2000s

The American Heart Association (AHA) and International Liaison Committee on Resuscitation (ILCOR) releases a statement regarding the use of AEDs on children. It is determined that an AED may be used for children one to eight years of age who have no signs of circulation.

In 2008, the AHA releases a statement about Hands-Only™ CPR, saying that bystanders who witness the sudden collapse of an adult should dial 911 and provide high-quality chest compressions by pushing hard and fast in the middle of the victim’s chest.

How to Choose the Best CPR Manikin for Your Organization

What You Need to Know about Feedback Requirements for CPR Manikins and More!

There are plenty of CPR training manikins on the market, but not all dummies are created equal. Know what to look for when choosing a CPR manikin, so you can find the one that’s right for your training program.

New Requirements For American Heart Association CPR Classes

As of January 31, The American Heart Association (AHA) will require the use of an instrumented directive feedback device in all courses that teach adult CPR skills. These devices help ensure your students are compressing deep and fast enough for effective CPR.

If your mankins are looking a little worse for wear and you are considering replacements, be sure to invest in high-quality training manikins with real-time audiovisual and corrective evaluation instruction on chest compression rate, depth, chest recoil, and proper hand placement during CPR training.

“Specific and targeted feedback is critical to students understanding and delivering high-quality CPR when faced with a cardiac emergency. Incorporating feedback devices into adult CPR courses improves the quality and consistency of CPR training, which increases the chance of a successful outcome when CPR is performed,” noted AHA volunteer and professor, Mary Elizabeth Mancini, Ph.D., MSN.  

Using American Heart Association-approved CPR dummies with feedback improves training quality and provides consistency

“When CPR is taught and performed according to the American Heart Association’s CPR and ECC Guidelines, chest compressions are delivered at a rate of 100 to 120 compressions per minute and a depth of at least two inches. To comply with the new course requirement, feedback devices must, at a minimum, measure and provide real-time audio and/or visual feedback on compression rate and depth, allowing students to self-correct or validate their skill performance immediately during training” (AHA).

As a CPR instructor, you undoubtedly keep an eye on your students’ form; however, you also know that it can be tough to watch every student simultaneously! (Don’t forget to share our CPR Playlist with your students!) Manikins with built-in immediate feedback improves training and makes for a better lifesaver.

Other Considerations for Choosing a CPR Manikin

Are You Traveling to Your Instructional Sites?

If you do a lot of on-site CPR training that requires traveling to different locations, you should consider a smaller, lightweight manikin. Look for a device that’s easy to carry, easy to set up, and easy to clean! 

On the other hand, if your trainings are held at outdoor worksites or on rough concrete floors, you may want to prioritize durability over portability.  The Prestan Professional Adult Jaw Thrust Training Manikin, for example, is durable, reliable and well-loved by CPR instructors!

“The Prestan manikin has a unique light-up system under the chest skin near the shoulder. A series of small indicator lights will let you know if the student is pumping at the correct rate. When the student has two green lights, he or she is right on target at 100 beats per minute. When testing the Prestan, we found the lights to be very helpful, accurate, and easy to see” (Occupational Health and Safety).

Which CPR Manikin Features Are Most Important?

  • Feedback: With new CPR requirements on the horizon, make sure your new manikin has a directive feedback device!
  • AED-trainer compatibility: While you’re at it, you may also want to make sure that it’s AED-trainer compatible.
  • Latex-free: As many people are allergic to latex, make sure your manikin is latex-free! (Both Laerdal and Prestan CPR dummies are latex-free).
  • Heimlich compatibility: If you’re also teaching first aid, make sure that your students will be able to practice abdominal thrusts on the manikin.
  • Skin tone: both Laerdal and Prestan offer skin tone choices.
  • Lung Systems: Lung systems vary depending on the brand of manikin you select. Some feature reusable lungs with washable mouth/nose pieces and some are disposable.

(Almost) Everything You Need to Know About CPR and AEDs

What is CPR? What Are AEDs? We Have the Answers!

Coming off the heels of a heart-pounding CPR and AED Awareness week, we realized that although we had a great time with our CPR Songs: Greatest Hits to Save Lives, it might be wise to share some general information about CPR and AEDs.

Because it’s impossible to teach you everything you need to know about CPR and AEDs in the space of a blog, we’re happy to share the top 10 things you need to know about the life-saving procedure and device. For everything you need to know, sign up for a CPR and AED training class today!

5 Things You Need to Know About CPR:

What is CPR?

CPR, or cardiopulmonary resuscitation, is an easy-to-learn first aid technique that can keep the victims of a sudden cardiac arrest (SCA) or other medical emergency alive until medical professionals can take over.

What Does CPR Do?

CPR keeps blood pumping through the body, which helps maintain vital organ function. CPR has two primary goals: to keep oxygen flowing in and out of the lungs and to keep oxygenated blood flowing throughout the entire body.

Anyone Can Learn CPR

Although real-life doctors (and the actors who just play them on TV) perform CPR professionally, CPR training is easy and anyone can do it. With more than 350,000 cardiac arrests occurring each and every year, amateurs are welcome!

In many instances, “blended” courses allow busy folks to complete the text-based portion of the course online at their own pace and convenience. Once you’ve passed the online course, a focused 3-4 hour hands-on skills workshop rounds out the training. Wondering what you’ll learn in a CPR or First Aid class? Read our post on the subject!

CPR Can Be Tiring

Performing CPR can be physically demanding. High-performing CPR requires 100-120 deep and steady compressions per minute, so head to the gym and start working on your upper body strength and cardio! Take AED.com CPR playlist with you, while you’re at it! Should you be called upon to perform CPR in an emergency, you may find yourself getting tired, so if possible switch off with another person every couple of minutes.

Hands-Only CPR is Effective

Hands-only CPR (also known as compression-only CPR) is CPR without rescue breaths. The American Heart Association has noted that “Hands-only CPR carried out by a bystander has been shown to be as effective as CPR with breaths in the first few minutes during an out-of-hospital sudden cardiac arrest for an adult victim.”

5 Things You Need to Know About AEDs:

What is an AED?

An automated external defibrillator (AED) is a small, portable medical device. When its pads are attached to a person’s chest, the AED can analyze an individual’s heart rhythm and deliver a shock, if necessary, to restart his or her heart. Bystanders, as well as medical professionals, can use AEDs.

How Does an AED Work?

The device works by measuring an unresponsive person’s heart rhythm and delivering a shock to restart the heart or to shock the heart back into the correct rhythm. After analyzing the heart rhythm, automated voice instructions and text prompts tell the rescuer how to proceed. If defibrillation is necessary, the device will warn responders to stay clear of the victim while the shock is delivered. If CPR is indicated, the AED will instruct the rescuer to continue performing CPR.

When Do I Use an AED?

Sudden cardiac arrest can occur anytime, anywhere, and without warning. Call 911 and get the AED if someone becomes suddenly unresponsive, stops breathing, or does not respond when you tap or shake the shoulder firmly and ask, “Are you OK?”

Where Can I Find an AED?

Although laws for the placement of AEDs vary, many states require AEDs in public areas like gyms, schools, sports stadiums, and community centers. AEDs should be kept in a well-marked and publicly accessible location. If you don’t know where your office or workplace keeps the AED, find out! You never know when you might be called upon to use it.

If AEDs Are So Easy To Use, Why Do I Need Training?

Not only will training teach you how to respond quickly in the event of a cardiac emergency, but you’ll also learn how to activate the EMS system and act with confidence. Training also provides hands-on familiarity with an AED and teaches you how to avoid potentially dangerous situations.
