When Was CPR Developed? Your Guide to the History of Cardiopulmonary Resuscitation
I often think about how lucky we are to live in an era where we know exactly what to do when someone’s heart stops. It feels like common knowledge now, but the journey to modern cardiopulmonary resuscitation (CPR) was a long, winding road filled with trial, error, and some very curious experiments.
Understanding where these techniques come from helps us appreciate why the Canadian Red Cross emphasizes specific steps today. The history of CPR isn't just a timeline of medical dates; it’s a story of how we learned to understand the human body and its resilience.
When was CPR Developed?
Modern resuscitation was established in 1960 when medical researchers codified the combination of mouth-to-mouth breathing and external chest compressions.
This breakthrough followed a decade of significant discoveries by experts who proved that rhythmic pressure on the chest could circulate oxygenated blood. Since then, organizations like the Canadian Red Cross have standardized these techniques to ensure everyone can provide effective help.

Why Does the History of CPR Matter Today?
Knowing the origins of CPR techniques helps us move past old myths and focus on what actually works. When we see how far we have come, it builds collective confidence to act. History proves that simple, consistent actions are the most effective way to help.
Evidence-Based Practice: Early methods like rolling people over barrels were based on guesswork. Today, we use specific depths and rates for compressions because decades of data prove they move blood most effectively.
Empowering the Public: Resuscitation used to be a closed-door medical secret. The shift in the 1960s to train non-professionals ensured that help starts the moment it is needed, right where people live.
Technological Integration: Modern AEDs exist because electrical engineers and doctors collaborated to make a complex "jolt" safe for everyone. This history allows us to use sophisticated technology with total, guided simplicity.

The Timeline of Modern CPR: How Was It Developed?
The evolution of modern resuscitation reveals how a mix of curiosity and collaboration changed everything. These methods finally came together once medical researchers combined effective breathing techniques with the landmark discovery of external chest compressions to help the heart.
The Early Days: Looking for Air
Long before we understood how to pump a heart from the outside, the focus was almost entirely on breathing. In the 1700s and 1800s, drowning victims were the primary focus of resuscitation efforts. Early societies used bellows to push air into lungs or even rolled people over barrels, mistakenly believing that physical agitation would bring them back.
In the early 20th century, Edward Sharpey-Schafer developed a method that became quite popular in Canada and the UK. Known as the prone pressure method, it involves lying a person face down and applying pressure to their lower back to move air in and out. While it was better than nothing, it didn't address the heart at all.
Around the same time, researchers like Sir Arthur Keith were exploring different ways to manage artificial breathing. These early methods were the standard technique for decades, but they had a major flaw: they couldn't help if the heart wasn't circulating blood.
The Spark: Electricity and the Heart
As the world became more electrified in the early 20th century, a new problem emerged. Linemen and electrical engineers were frequently suffering from electrical shocks on the job. These shocks of electricity would often cause the heart to quiver—a state called ventricular fibrillation—rather than stop entirely.
This is where the defibrillator idea began to take shape. Researchers realized that a well-timed jolt of electricity could actually stop the chaotic quivering and allow the heart to return to a natural rhythm. However, early devices were massive and only used in a hospital setting during open-chest surgery.
The Breakthrough: The Late 1950s
The most significant shift in how we help when people experience cardiac arrest happened in the late 1950s. This was the decade when the pieces of the puzzle finally came together.
Three names stand out in this era: Drs. William Kouwenhoven, Peter Safar, and James Jude. Their collaboration at Johns Hopkins University changed everything.
Peter Safar perfected the "mouth-to-mouth" breathing technique, proving it was far more effective than the older manual pressure methods.
William Kouwenhoven, whose expertise in physics helps explain his success, discovered that pressure on the chest could move blood.
James Jude realized that combining these chest compressions with Safar’s breathing could keep a patient alive long enough for a defibrillator to arrive.
During their research, they discovered that chest cardiac compressions alone could maintain up to 20%-33% of normal circulation. This was the birth of the resuscitation technique we recognize today.
Refining the Technique: From Manual to Standardized
Before this breakthrough, there was a hazardous lack of consistency. If you were in medical distress in 1950, what happened next depended entirely on who found you. The lack of standardization meant that even medical experts weren't always on the same page.
By 1960, the medical community officially recognized that a combination of cardiac massage (the old term for compressions) and rescue breathing was the primary first-aid technique for sudden cardiac arrest.
Kouwenhoven also continued his work on the hardware side, eventually helping to develop the first functioning closed-chest defibrillator, which was first used by Dr. Paul Zoll in 1956. This meant a person's chest didn't have to be cut open to reset the human heart to a normal rhythm.
The Canadian Connection and Safety Culture
In Canada, the adoption of these techniques moved quickly. The Canadian Red Cross and other organizations realized that for this to work, we couldn't just train doctors; we had to train everyone.
This shift created a new safety culture. We moved away from the idea that only professionals could help. Instead, we focused on responder preparedness. Today, Canadian Red Cross standards emphasize high-quality chest compressions and the use of Automated External Defibrillators (AEDs), which are essentially the user-friendly descendants of Kouwenhoven’s early inventions.
What Can You Expect from a Modern CPR Certification
Modern training focuses on building practical skills through hands-on experience. At BraveHeart First Aid, our half-day Canadian Red Cross course strips away complex medical theory, providing a clear path to gaining the confidence needed to help someone experiencing cardiac arrest, a stroke, or a breathing emergency.
Our CPR Course Covers:
Core Resuscitation Skills
Our training centers on high-quality chest compressions and rescue breathing. Participants practice the correct depth and rhythm required to keep blood moving through the body, ensuring the brain receives oxygen until professional help arrives on site.
AED Training and Safety
Using an Automated External Defibrillator is a primary focus. Courses demonstrate how to apply pads and follow the voice prompts of the device to deliver a shock safely and effectively when the heart quivers.
Choking Response Techniques
Participants learn how to identify and clear airway obstructions for adults, children, and infants. These interactive scenarios provide a step-by-step approach to dislodging objects and restoring normal breathing patterns for people of all ages.
The Check-Call-Care Method
Our foundational strategy teaches responders how to assess the scene for safety, contact emergency services, and begin providing care. It provides a reliable mental framework to follow when faced with a stressful or unexpected situation.
