We live in a digital age, an era filled with extraordinary advances in technology and communication. However, despite all the convenience and information available at our fingertips, one glaring issue stands out—many people don’t know how to perform CPR (Cardiopulmonary Resuscitation). This experience underscores the importance of knowing the basics of CPR. So today, let’s break down the ABCs of CPR: Airway, Breathing, and Circulation—three essential steps that form the foundation of basic life support and can make the difference between life and death.
Understanding Cardiopulmonary Resuscitation (CPR)
Cardiopulmonary resuscitation (CPR) is a life-saving emergency procedure that combines chest compressions with rescue breaths to restore blood circulation and breathing in a person who has stopped breathing or whose heart has stopped beating. When someone experiences cardiac arrest, their heart can no longer pump oxygenated blood to the brain and other vital organs. This lack of blood flow can lead to permanent brain damage or death within minutes.
CPR is a crucial skill that can be performed by anyone, regardless of their medical background, to help save a life in the event of a cardiac emergency. By performing chest compressions and rescue breaths, you can help maintain blood circulation and oxygenation until professional medical help arrives. Remember, every second counts in an emergency, and your quick action can make a significant difference.
The ABCs of CPR
The ABCs of CPR stand for Airway, Breathing, and Circulation. These three steps are the foundation of CPR and are performed in a specific sequence to ensure that the person receives the necessary care to survive. Here’s a closer look at each step:
-
A - Airway: The first step is to clear the airway. Tilt the person’s head back and lift their chin to open the airway. This maneuver helps ensure that air can flow into the lungs when you start rescue breathing or chest compressions.
-
B - Breathing: Next, check for normal breathing. If the person is not breathing or if their breathing is abnormal, provide rescue breaths. Pinch the person’s nose shut, place your mouth over theirs, and give two breaths, each lasting about one second. Watch for the chest to rise with each breath.
-
C - Circulation: Finally, perform chest compressions to restore blood circulation to the vital organs. Place the heel of one hand on the center of the person’s chest, with the other hand on top. Push down hard and fast, aiming for a depth of at least 2 inches in adults. Continue with cycles of 30 compressions followed by two rescue breaths.
By following the ABCs of CPR, you can help ensure that the person receives the critical care they need to survive until emergency medical professionals arrive.
Airway
The airway is the passage that allows air to travel into and out of the lungs. It is made up of several parts: the nose, mouth, pharynx (throat), larynx (voice box), and trachea. A blocked airway prevents oxygen from reaching the lungs and subsequently the brain, which can result in irreversible brain damage in minutes.
In many cases, especially in children, the tongue is the most common cause of airway obstruction. To prevent airway blockages, especially in young children, be mindful of the following:
-
Avoid giving honey to infants under 1 year of age. Honey can lead to infant botulism, a rare but serious condition caused by toxins produced by bacteria in the honey.
-
Avoid foods or liquids containing raw eggs for children under 1 year old, as raw eggs may contain salmonella bacteria, which can cause severe food poisoning.
If a person is unresponsive and you suspect airway blockage, the first step in CPR is to open their airway by tilting the head back and lifting the chin. This simple maneuver can help clear the airway, ensuring that air can flow into the lungs when you start breathing or compressions.
Breathing
Breathing is the process that allows oxygen to enter the body and carbon dioxide to leave it. When someone stops breathing, their brain cells begin to die in just minutes due to a lack of oxygen. Immediate action is critical.
If the person isn’t breathing or if you are unsure, it’s important to start chest compressions. Performing mouth to mouth can also be crucial in providing the necessary oxygen to the victim. Even if you’re untrained in CPR, chest compressions can provide a temporary source of circulation, moving blood (and thus oxygen) throughout the body until professional medical help arrives.
Steps for Effective Chest Compressions:
Place one hand on top of the other and position them at the center of the person’s chest, just below the ribs, to perform cab cpr chest compressions.
Straighten your arms and push down hard and fast, aiming for at least 2 inches of compression depth in adults. Your compressions should be rhythmic, at a rate of about 100-120 compressions per minute.
Allow the chest to fully rise between compressions.
Remember, it’s more important to keep compressions going than to worry about breathing if you’re not trained. Effective chest compressions can save lives by maintaining blood flow to vital organs.
Circulation
Once the airway is open and you’ve initiated breathing or compressions, the next critical step is ensuring circulation. In other words, you need to ensure that the heart is pumping blood throughout the body.
Ensuring proper circulation is a critical component of emergency cardiovascular care, which aims to restore and maintain blood flow to the brain and other vital organs.
To check for circulation, place two fingers on the person’s carotid artery, located on the side of their neck, to feel for a pulse. If no pulse is detected, or if you’re unsure, continue with chest compressions.
Here’s a basic breakdown of circulation scenarios:
-
No pulse and no breathing: Immediately begin chest compressions and continue until help arrives.
-
Pulse but no breathing: Start rescue breathing by giving two breaths after every 30 compressions. Each breath should last about one second.
-
Breathing but unconscious: Monitor the person until emergency medical help arrives.
In the case of an AED being available, turn it on and follow the device’s instructions. The AED will guide you through the process of shocking the heart, which can help restart it in cases of ventricular fibrillation or ventricular tachycardia—two potentially fatal heart rhythms.
CAB CPR: The Updated Guidelines
In 2010 there were updates to the CPR guidelines to prioritize chest compressions over airway and breathing. The new sequence, known as CAB CPR, stands for Chest compressions, Airway, and Breathing. This change was made to emphasize the importance of starting chest compressions as soon as possible to restore blood flow to the brain and other vital organs.
The rationale behind this update is that immediate chest compressions can help maintain blood circulation and oxygenation, which are crucial for the survival of cardiac arrest victims. By starting chest compressions right away, you can help ensure that oxygenated blood continues to flow to the brain and other vital organs, increasing the chances of a positive outcome.
To perform CAB CPR, follow these steps:
-
Chest Compressions: Begin with 30 chest compressions, pushing hard and fast on the center of the person’s chest.
-
Airway: After the compressions, open the airway by tilting the head back and lifting the chin.
-
Breathing: Provide two rescue breaths, ensuring that the chest rises with each breath.
By prioritizing chest compressions, CAB CPR helps ensure that blood flow is maintained, giving the person the best chance of survival.
Cardiac Arrest Symptoms and Response
Cardiac arrest occurs when the heart suddenly stops beating, and blood flow to the brain and other vital organs is interrupted. Recognizing the symptoms of cardiac arrest and responding quickly is crucial. Symptoms of cardiac arrest include:
-
Sudden collapse
-
Loss of consciousness
-
No breathing or abnormal breathing
-
No pulse
If you witness someone experiencing cardiac arrest, call 911 or your local emergency number immediately. Time is of the essence, and prompt action can save a life. While waiting for emergency medical services to arrive, begin CPR if you are trained to do so. Start with chest compressions to maintain blood flow to the brain and other vital organs. If an AED (Automated External Defibrillator) is available, use it as soon as possible, following the device’s instructions.
Performing CPR on Adults, Children, and Infants
CPR techniques vary depending on the age of the person. Here are some general guidelines for performing CPR on adults, children, and infants:
CPR for Adults
To perform CPR on an adult, follow these steps:
-
Call 911 or your local emergency number.
-
Check the person’s airway, breathing, and circulation (ABCs).
-
Start chest compressions by placing the heel of one hand on the center of the person’s chest and the other hand on top of the first hand.
-
Push down on the chest with the heel of your hand to a depth of 2-3 inches.
-
Provide 30 chest compressions followed by two rescue breaths.
-
Continue this cycle until emergency medical personnel arrive.
Takeaway on Cardiopulmonary Resuscitation
If you ever find yourself in a situation where someone is having a heart attack or has gone into cardiac arrest:
-
Help them lie down and raise their feet if they’re conscious.
-
Call 911 or have someone else do it immediately.
-
Start chest compressions. In the absence of breathing or pulse, you need to act quickly.
Performing CPR on Adults with an AED:
-
Place your hands in the correct position and push hard enough so that the chest moves about 2 inches with each compression.
-
Perform cycles of 30 compressions followed by two breaths until help arrives or the person regains consciousness.
CPR for Children:
-
Use child-sized resuscitation equipment when possible. This will make rescue breaths more effective than mouth-to-mouth.
-
Always aim for gentler compressions, as children's bodies are smaller and more fragile.
Conclusion
CPR is a critical life-saving skill that everyone should know. By mastering the ABCs of CPR—Airway, Breathing, and Circulation—you’ll be better prepared to take action during an emergency. You may not know how long someone has been without oxygen or if their heart has stopped, but quick action with airway clearance, chest compressions, and rescue breaths can significantly increase their chances of survival.
You never know when this knowledge could help save a life—maybe even yours or someone you love.
