Introduction
Knowing how to perform CPR can help you respond appropriately when someone experiences a life-threatening emergency. Cardiopulmonary resuscitation (CPR) is an emergency response used when a person is unresponsive and not breathing normally.
In these situations, acting promptly, contacting emergency services, and following dispatcher instructions are important. CPR can help maintain circulation to vital organs until professional medical assistance arrives.
This beginner's guide explains the basic principles of CPR, how to recognize when it may be needed, how an automated external defibrillator (AED) fits into an emergency response, and why practical first aid training is valuable.
Important: This article provides general educational information and does not replace certified hands-on CPR training, emergency medical care, or instructions from local emergency services.
What Is CPR?
CPR stands for cardiopulmonary resuscitation. It is an emergency procedure used when someone is unresponsive and not breathing normally.
The purpose of CPR is to help maintain blood circulation and oxygen delivery to vital organs while waiting for emergency medical professionals.
CPR generally involves chest compressions and, depending on the situation and the rescuer's training, rescue breaths. The appropriate technique can vary depending on the person's age and circumstances.
Because CPR is a physical skill, reading about it is different from learning and practicing it. Hands-on training can help people understand correct positioning, compression technique, rescue breathing, and how to use an AED.
When Might CPR Be Needed?
CPR may be needed when a person:
Is unresponsive
Is not breathing normally
Has abnormal or gasping breathing
Appears to be experiencing a cardiac emergency
If a person is unresponsive and not breathing normally, treat the situation as an emergency. Contact your local emergency service and follow the instructions provided by the emergency dispatcher.
Do not assume that gasping or unusual breathing is normal breathing. When you are uncertain, seek emergency assistance and follow dispatcher guidance.
Step 1: Make Sure the Scene Is Safe
Before approaching someone who may need first aid, check whether the area is safe.
Potential hazards can include:
Moving traffic
Fire or smoke
Electrical hazards
Dangerous machinery
Chemicals
Deep or moving water
Unstable structures
Do not put yourself in danger while trying to help someone else. If the area is unsafe and you cannot make it safe, move to a safe location and contact the appropriate emergency service.
Once the scene is reasonably safe, you can assess the person.
Step 2: Check Responsiveness and Breathing
Check whether the person responds to you and determine whether they are breathing normally.
If the person is unresponsive and not breathing normally:
Activate emergency medical assistance.
Follow emergency-dispatch instructions.
Begin appropriate CPR if you are able to do so.
Ask someone nearby to locate an AED if one is available.
Continue providing assistance until professional help arrives or the situation changes.
If you are alone, follow the emergency dispatcher's instructions regarding contacting emergency services and starting CPR.
Step 3: Begin Appropriate CPR
For an unresponsive adult who is not breathing normally, trained rescuers generally begin chest compressions on the center of the chest.
The exact CPR technique—including hand placement, compression depth, compression rate, and whether rescue breaths should be provided—should be learned through current, recognized CPR training.
If you have received CPR training, use the technique you were taught. If you have not received formal training or are unsure what to do, contact emergency services and follow the dispatcher's instructions.
The important principle is to recognize a possible cardiac emergency, activate professional help quickly, and provide appropriate assistance within your level of training.
Step 4: Use an AED When Available
An automated external defibrillator (AED) is a device designed to assess certain heart rhythms and, when appropriate, provide an electrical shock.
If an AED is available:
Turn the AED on.
Follow its voice or visual instructions.
Expose the person's chest as directed.
Attach the AED pads according to the device instructions.
Make sure nobody touches the person when the AED is analyzing the heart rhythm.
If the AED instructs you to deliver a shock, make sure everyone is clear of the person.
Continue following the AED's instructions.
You do not generally need to be a medical professional to operate an AED. The device provides instructions to guide the rescuer through the process.
What If the Person Starts Breathing?
If the person begins breathing normally but remains unresponsive, continue following your first aid training and the instructions provided by emergency services.
Keep monitoring the person and be prepared to respond if their condition changes.
Do not leave the person alone unless it is necessary to obtain emergency assistance or an AED. Continue monitoring them until professional responders take over.
CPR for Children and Infants
CPR for children and infants requires age-specific considerations. Children and infants should not simply be treated as smaller adults.
The appropriate response can depend on the child's age, size, condition, and the rescuer's training.
Parents, caregivers, teachers, childcare professionals, and anyone responsible for children can benefit from learning pediatric CPR and first aid through an appropriate practical course.
If a child or infant is unresponsive and not breathing normally, contact emergency services and follow the instructions provided by the dispatcher.
Why Practical CPR Training Matters
Reading about CPR can help you understand the basic concepts, but CPR is a practical skill.
Hands-on training can help learners develop:
Correct chest-compression technique
Appropriate hand positioning
Confidence in responding to emergencies
Familiarity with AED equipment
Awareness of different CPR procedures
Experience responding to realistic emergency scenarios
Understanding of when and how to contact emergency services
Regular refresher training can also be useful, particularly for people who have workplace, childcare, education, or community responsibilities.
CPR and First Aid Training Together
CPR is only one part of emergency first aid.
A broader first aid course can help learners understand how to respond to a variety of situations, including:
Choking
Severe bleeding
Burns
Fractures and injuries
Fainting
Shock
Heart-related emergencies
Stroke warning signs
Other potentially serious medical situations
Learning these topics together can help people develop a more complete approach to emergency response.
to explore essential first aid topics and emergency-response principles.
Common CPR Mistakes to Avoid
When responding to an emergency, avoid actions that could put yourself or the person at additional risk.
Some important points to remember include:
Do Not Enter an Unsafe Scene
Your own safety comes first. Do not approach someone if there are hazards you cannot safely manage.
Do Not Assume Gasping Is Normal Breathing
Unusual gasping or abnormal breathing can occur during a cardiac emergency. If the person is unresponsive and not breathing normally, seek emergency assistance immediately.
Do Not Delay Emergency Assistance
CPR should not replace professional medical care. Activate emergency services as soon as a serious cardiac emergency is suspected.
Do Not Ignore AED Instructions
If an AED is available, turn it on and follow its instructions carefully. Make sure nobody touches the person when the device instructs rescuers to stand clear.
Do Not Rely Only on Written Instructions
CPR involves physical skills that are difficult to learn fully from an article. Practical training provides an opportunity to learn and practice the technique safely.
How Can You Prepare for a CPR Emergency?
Preparation can make it easier to respond when an emergency occurs.
Consider:
Learning CPR through a recognized training provider.
Becoming familiar with AED locations in your workplace, school, gym, or community.
Refreshing your CPR and first aid knowledge regularly.
Learning how to contact your local emergency services.
Keeping basic first aid supplies accessible where appropriate.
Learning additional first aid skills such as choking response and bleeding control.
Being prepared does not mean you will always know exactly what to do. It means you have a foundation that can help you respond more appropriately while professional assistance is being arranged.
