The Science Behind CPR: How Your Actions Save Lives

The Science Behind CPR: How Your Actions Save Lives

When someone collapses at home, work, or on the street, quick action is crucial to prevent further complications. Whether it is due to a heart attack or a stroke, ensuring vital organs receive sufficient oxygen is crucial. In such situations, performing cardiopulmonary resuscitation (CPR) can save a life. At Quick CPR, we provide personalized CPR classes to meet the needs of different settings, such as communities, schools, and workplaces. Our seasoned instructors ensure you receive excellent training and certification, equipping you with all the tools to respond to emergencies.

The Science Behind CPR

During a cardiac arrest, the heart stops beating effectively, cutting off blood flow and oxygen supply to the body. Brain cells often die within minutes of oxygen deprivation, and victims may experience irreversible damage within 4 minutes or death after 7 minutes without intervention. CPR is an effective and simple technique that you can learn and use to keep oxygenated blood flowing to the brain and heart until expert help arrives.

CPR involves performing compressions on the center of the victim’s chest, about 100 to 120 times per minute, and a depth of 2 inches. This repetitive act helps to squeeze the heart and pump blood to vital organs, preventing further complications. If the victim doesn’t respond to chest compressions, performing rescue breaths may be the best course of action.

Rescue breaths are effective in filling the lungs with air and delivering oxygen to the blood. During CPR training in Austell, GA, you’ll learn the proper technique for performing this life-saving act. Tilt the victim’s head back gently and pinch their nose to create a seal. Blow air into their mouth once every six seconds, and conduct chest compressions at intervals.

Combining chest compressions and rescue breaths replicates the function of vital organs until they start working or a paramedic takes over. Additionally, CPR classes may involve automated external defibrillator (AED) training to ensure you effectively use this device to restore the heart rhythm.

CPR and the Heart

When someone suffers a cardiac arrest, their heart beats fast or slow, or stops to pump blood. This is usually a result of different factors, such as an electrical shock, a heart attack, a drug overdose, trauma, or a severe allergic reaction. During a cardiac emergency, the blood flow to the brain and heart is interrupted, and they start to die within minutes.

Performing CPR is vital to keep the blood circulating in the body by squeezing the heart to pump blood. High-quality CPR minimizes the damage to heart muscles and other organs, giving victims a chance to recover after resuscitation.

CPR and the Brain

As mentioned, cardiac arrest cuts off blood and oxygen circulation to the brain. If the cells are deprived for more than four minutes, they will die rapidly and cause severe brain damage, or even death. CPR plays a crucial role in directing oxygen and glucose in the blood to the brain. By filling the victim’s lungs with air and forcing it into the blood, CPR prevents damage to the brain cells and preserves their function.

The Importance of CPR

Now that you know the science behind CPR and how your actions can save a life, learning the crucial skills needed is crucial. Research shows that CPR can make a huge difference in cardiac arrest victims, as it significantly increases survival rates when performed correctly. When someone collapses, quick intervention is crucial to reduce the risk of complications such as infection or organ failure. With this in mind, ensuring you have the proper skills to save a life is crucial.
