Cardiopulmonary Resuscitation (CPR) is a critical life-saving skill that everyone should know. Whether it’s a family member, friend, or even a stranger, knowing how to perform CPR can make the difference between life and death in an emergency. When someone experiences a cardiac event, every second counts. Without proper intervention, the chances of survival decrease rapidly. Imagine being in a situation where a loved one is having a heart attack or suddenly collapses, and you have the power to help but lack the knowledge and skills to act. Learning CPR gives you the ability to take action and provide the victim with the best possible chance of survival. This article will delve into the details of CPR, explain why it’s essential for everyone, and how you can learn this vital skill through resources like MyCPR NOW.
Why is CPR Important?
CPR is important because it can dramatically improve the chances of survival in a cardiac emergency. When the heart stops beating, blood circulation ceases, depriving the brain and other vital organs of oxygen. Without intervention, permanent brain damage can occur within 4 to 6 minutes, and death can follow shortly after. CPR works to restore blood flow and oxygenation to the brain and organs until professional medical help can take over.
The ability to perform CPR significantly increases the survival rate for victims of sudden cardiac arrest (SCA). Statistics indicate that immediate CPR can double or even triple a victim’s chances of survival, particularly when performed in conjunction with the use of an Automated External Defibrillator (AED). Unfortunately, many people are hesitant to perform CPR because they feel unprepared, lack confidence, or have not received formal training. This is why attending a CPR class and becoming certified is so important.
What Does CPR Consist of?
CPR is a coordinated effort that involves three essential components: chest compressions, rescue breaths, and the use of an AED. Each of these plays a crucial role in maintaining oxygenation and circulation in the victim's body.
1. Chest Compressions
Chest compressions are the most important aspect of CPR. They manually pump the heart, helping maintain circulation in the body. When the heart stops beating effectively, chest compressions take over the job of pumping blood to the brain and other organs. Proper chest compressions are critical to ensure the brain and heart continue to receive oxygenated blood.

How to perform chest compressions:
- Hand placement: Place the heel of one hand on the center of the victim’s chest (on the lower half of the breastbone), and place your other hand on top of the first.
- Compression depth: For adults, compress the chest at least 2 inches deep. For children, compress about 2 inches, and for infants, compress about 1.5 inches using two fingers.
- Compression rate: Aim for a rate of 100-120 compressions per minute. This rhythm can be likened to the beat of the song “Stayin’ Alive” by the Bee Gees, which helps rescuers maintain the right pace.
- Let the chest recoil: After each compression, allow the chest to fully recoil to ensure the heart refills with blood.
The quality of compressions—depth, speed, and recoil—directly affects the likelihood of survival. Shallow or inconsistent compressions reduce the effectiveness of CPR, meaning less oxygen reaches the brain and heart.
2. Rescue Breaths
Rescue breathing provides vital oxygen to the lungs of a victim who is not breathing. Oxygen is necessary for the blood to carry it to the organs and tissues. Without rescue breaths, the victim’s body will quickly run out of oxygen, leading to cellular damage and death.
-
How to perform rescue breaths:
- Open the airway: Tilt the victim’s head back slightly and lift the chin to open the airway.
- Deliver the breaths: Pinch the victim’s nose closed, place your mouth over theirs, and give 2 breaths. Each breath should last about 1 second, and you should see the chest rise with each breath.
- Compression-to-breath ratio: For adults, the standard ratio is 30 chest compressions followed by 2 rescue breaths. For children and infants, the ratio is the same if you are the only rescuer. However, if there are two rescuers, the ratio for children and infants changes to 15 compressions followed by 2 rescue breaths.
Although hands-only CPR (compressions without breaths) has been proven effective in certain cases (especially in adult sudden cardiac arrest), rescue breaths remain an important part of traditional CPR, particularly for children, drowning victims, and those with respiratory emergencies.
3. Automated External Defibrillator (AED)
An AED is a portable device that analyzes the heart’s rhythm and delivers an electric shock if needed. The shock helps the heart return to a normal rhythm, especially in cases of ventricular fibrillation (VF), where the heart’s electrical activity becomes chaotic, preventing it from pumping blood effectively. AEDs are designed for easy use, with voice prompts to guide even untrained bystanders through the process.
-
How to use an AED:
- Turn on the AED: The device will provide voice instructions on what to do next.
- Apply the pads: Attach the electrode pads to the victim’s bare chest, as indicated by the diagram on the pads.
- Let the AED analyze: Stand clear and allow the AED to analyze the heart rhythm. If a shock is needed, the device will instruct you to press a button to deliver the shock.
- Resume CPR: After the shock, continue CPR immediately, starting with chest compressions.
The timely use of an AED, especially when combined with CPR, can greatly increase the chances of survival. For every minute that passes without defibrillation, the chances of survival decrease by 7-10%.
CPR Variations for Different Age Groups
CPR techniques vary depending on the age of the victim—adult, child, or infant. Understanding these variations is critical to ensuring the most effective care is given.
Adult CPR
- Compression ratio: 30 compressions to 2 breaths, whether one or two rescuers.
- Compression depth: At least 2 inches deep.
- Technique: Use both hands placed on the center of the chest.
Child CPR (1 year to puberty)
- Compression ratio: 30 compressions to 2 breaths for one rescuer; 15 compressions to 2 breaths for two rescuers.
- Compression depth: About 2 inches deep.
- Technique: Use one or two hands depending on the size of the child.
Infant CPR (under 1 year)
- Compression ratio: 30 compressions to 2 breaths for one rescuer; 15 compressions to 2 breaths for two rescuers.
- Compression depth: About 1.5 inches deep.
- Technique: Use two fingers for compressions.
These variations are designed to provide the correct balance of force and oxygen delivery based on the size and physiology of the victim.
Learning CPR: It’s Easier Than You Think
CPR is a skill that anyone can learn, regardless of age or experience. It may seem intimidating at first, but CPR is not difficult, and once learned, it can be easily remembered. Many people hesitate to perform CPR because they fear they will do it incorrectly or hurt the victim. However, doing something is always better than doing nothing. CPR training provides the confidence and skills needed to act quickly and effectively in an emergency.
- Practice: In a CPR class, you will practice chest compressions, rescue breaths, and AED use on mannequins, allowing you to gain confidence in your abilities.
- Online Training: For those unable to attend in-person classes, online options such as those offered by MyCPR NOW provide comprehensive training materials, video demonstrations, and exams that can be completed at your own pace.
