Cardiopulmonary resuscitation (CPR) was invented in 1960, when Drs. Jude, Safar, and Kouwenhoven successfully combined chest compressions and rescue breathing.
The American Heart Association (AHA ) in 1963establshed it as the standard for treating cardiac arrest
Earlier resuscitation techniques existed, but none were as effective as the combined method introduced in 1960.
Cardiopulmonary resuscitation (CPR) is a life-saving technique to restore breathing and circulation to individuals who have experienced cardiac arrest or other medical emergencies. While the modern version of CPR has been around for over 50 years, artificially inducing circulation and respiration dates back to ancient times. In this blog post, we'll explore the fascinating history of CPR, from its earliest iterations to the modern technique used today for successful resuscitation.
What are the origins of artificial respiration and CPR techniques?
The earliest recorded instances of artificial respiration date back to ancient Greece and Rome. In the first century A.D., the Greek physician Galen described a method of resuscitating drowned victims by blowing air into their lungs through a reed. This technique was later refined by Roman physicians, who added abdominal pressure to force air into the lungs.
Over the next few centuries, various methods of artificial respiration were developed, including the use of bellows and the manual compression of the chest. However, these methods were often ineffective, and many individuals who experienced cardiac arrest or respiratory failure died.

The first recorded attempt at resuscitation dates back to 1740, when the Paris Academy of Sciences recommended mouth-to-mouth resuscitation to revive drowning victims. However, it was not until the 19th century that the first documented case of successful CPR was recorded when Dr. Friedrich Maass used chest compressions to revive a patient who had been suffering from a drug overdose.
Following this breakthrough, there were several attempts to develop CPR techniques that could be widely applied. In 1903, Dr. George Crile proposed that external chest compressions alone could be used to resuscitate people whose hearts had stopped. He performed a series of experiments on dogs and concluded that chest compressions alone were sufficient to restore circulation.
In the 1920s, Dr. Charles L. Beck developed the "Holger-Nielsen method" of external cardiac massage. This technique involved using a rubber bulb to pump air into the lungs while simultaneously compressing the chest to stimulate blood flow. This method was widely used during the Second World War and became the standard for CPR during the 1940s.
However, the Holger-Nielsen method was not without its flaws. It required two people to administer the technique and was not always successful in reviving patients. As a result, researchers continued to seek more effective and efficient CPR techniques.
Modern CPR
In the 1960, a team of researchers led by Dr. James Jude, Dr. Peter Safar, and Dr. William Kouwenhoven developed the first modern technique for cardiopulmonary resuscitation. This technique, which combined chest compressions and artificial respiration, became known as CPR.
The development of CPR was a breakthrough in emergency medicine. Before its invention, there was no effective treatment for cardiac arrest, and the survival rate for individuals who experienced sudden cardiac arrest was less than 10%.
However, with the advent of CPR, survival rates began to improve dramatically. Today, the American Heart Association reports that nearly 45% of individuals who experience cardiac arrest outside of a hospital setting survive when CPR is performed immediately.
Who were the pioneers of modern CPR, and how did they develop the technique?
The pioneers of modern CPR were Dr. James Jude, Dr. Peter Safar, and Dr. William Kouwenhoven. Their groundbreaking work in the 1960 revolutionized the field of emergency medicine by introducing a combination of chest compressions and artificial respiration to treat cardiac arrest or respiratory failure.
Dr. Jude was the first to recognize that chest compressions alone were insufficient to restore circulation and breathing. So he began experimenting with various combinations of chest compressions and artificial respiration. After several years of research, he developed a technique that successfully restored circulation and breathing in patients who had experienced cardiac arrest or respiratory failure.
Dr. Safar then developed the first algorithms for administering CPR, which helped make the technique easier to learn and apply in an emergency setting. Finally, Dr. Kouwenhoven developed a "closed-chest cardiac massage technique," which proved more effective than open-chest techniques.
The combined contributions of these three pioneers revolutionized the field of emergency medicine and made CPR one of the essential life-saving techniques used today.

What was the survival rate for cardiac arrest before modern CPR?
Before the invention of modern CPR, the survival rate for individuals who experienced sudden cardiac arrest was less than 10%. However, with the advent of CPR, survival rates improved dramatically. Today, the American Heart Association reports that nearly 45% of individuals who experience cardiac arrest outside of a hospital setting survive when CPR is performed immediately.
Promotion of CPR Training
In 1972, the American Heart Association developed the first formal CPR training course designed for medical professionals. The course included a combination of classroom instruction and hands-on training using mannequins. Leonard Cobb launched Medic II, the world's first mass citizen training in CPR in the United States.
In the 1980s, the American Heart Association launched a public awareness campaign to promote the importance of CPR training to improve the chances of survival. The "Friends and Family" campaign encouraged everyone to learn CPR to potentially save a loved one's life.
The Impact of CPR
The impact of CPR on emergency medicine cannot be overstated. In addition to improving survival rates for individuals who experience cardiac arrest, CPR has also been used to save the lives of individuals who experience drowning, drug overdoses, and other medical emergencies.
In addition to its life-saving benefits, CPR has also had a significant impact on public health education. In many countries, including the United States, CPR training is mandatory for certain professions, such as healthcare providers and emergency responders. In addition, many schools and community organizations also offer CPR training to the general public, which has helped to increase awareness and preparedness for medical emergencies.
Current CPR Techniques
In 2000, the American Heart Association revised the CPR guidelines to emphasize chest compressions as the most critical component of CPR. They recommended a ratio of 30 compressions to two rescue breaths, and in 2010, they further simplified the technique by recommending continuous chest compressions with only occasional breaths.
