Heartbeats: CPR Basics

Cardiopulmonary Resuscitation (CPR) is a life-saving technique that can mean the difference between life and death in emergencies like cardiac arrest or drowning. It's a skill that everyone should learn because you never know when you might need to use it to save a life. In this comprehensive guide, we will cover the basics of CPR, step-by-step instructions, and key information you need to know to perform effective CPR.

What is CPR?

CPR Defined

Cardiopulmonary Resuscitation, commonly known as CPR, is an emergency procedure performed when someone's heart stops beating or they stop breathing. CPR combines chest compressions and rescue breaths to circulate oxygenated blood to the brain and vital organs until professional medical help arrives.

The Importance of CPR

CPR is crucial because it keeps the blood flowing to the brain and other vital organs, preventing brain damage and increasing the chances of survival. Without CPR, brain cells can begin to die within minutes, which is why immediate action is vital.

Recognizing When CPR is Needed

Signs of Cardiac Arrest

Performing CPR is necessary when you come across someone who is unresponsive and not breathing or not breathing normally. In some cases, victims may gasp for breath, which is considered abnormal breathing and should prompt immediate CPR.

Calling 911

Before starting CPR, it's crucial to call 911 or the local emergency number if someone else is available to make the call. If you are alone and have access to a speakerphone or hands-free device, call for help before beginning CPR. Professional medical assistance is critical in these situations.

CPR Steps

1. Ensure Safety

Before approaching the victim, ensure the scene is safe for both you and the victim. Be aware of any potential hazards, such as traffic, fire, or electrical dangers. Your safety is a priority.

2. Check for Responsiveness

Tap the victim's shoulder and shout loudly to check for a response. If they do not respond and you are alone, call 911 immediately.

3. Open the Airway

If the victim is unresponsive, open their airway by tilting their head backward and lifting their chin. This helps ensure that the airway is clear for breathing.

4. Check for Breathing

Look, listen, and feel for breathing. Watch for chest rise and fall, listen for breath sounds, and feel for exhaled air. If the victim is not breathing or not breathing normally, it's time to start CPR.

5. Begin Chest Compressions

Place the heel of one hand on the center of the victim's chest, just below the nipple line. Place the other hand on top and interlock your fingers. Position yourself with your shoulders directly above your hands.

6. Compression Technique

Start chest compressions by pushing hard and fast. Compress the chest at least 2 inches deep at a rate of 100-120 compressions per minute. Allow the chest to fully recoil between compressions, and maintain a steady rhythm.

7. Rescue Breaths (If Trained)

If you are trained in CPR and willing to provide rescue breaths, give two rescue breaths after every 30 compressions. Ensure that each breath results in visible chest rise. If you are unwilling or unable to provide rescue breaths, continue with chest compressions only.

8. Continue CPR

Continue performing CPR until one of the following occurs:

  • Professional medical help arrives.
  • The victim shows signs of life, such as breathing or responsive movement.
  • You are too exhausted to continue.


Automated External Defibrillators (AEDs)

AEDs are portable devices that can analyze a person's heart rhythm and deliver an electric shock if necessary. If an AED is available, use it as soon as possible, following the device's voice prompts. AEDs can significantly increase the chances of survival in cases of cardiac arrest.

Special Considerations

CPR for Infants and Children

CPR techniques for infants and children differ from those for adults. It's essential to adapt your approach based on the victim's age. For infants, use two fingers for chest compressions, and for children, use one or two hands depending on the child's size.

Choking Victims

If a conscious victim is choking and cannot breathe, perform abdominal thrusts (Heimlich maneuver) to dislodge the obstruction. Only perform CPR if the victim becomes unresponsive.

CPR Training

Importance of Training

While it's possible to perform CPR without formal training, taking a CPR course is highly recommended. Training provides you with the confidence and skills to perform effective CPR. Many organizations offer CPR courses.

Hands-On Practice

CPR training includes hands-on practice with manikins and often covers other essential skills like using AEDs and providing CPR to infants and children.


Cardiopulmonary Resuscitation (CPR) is a vital skill that everyone should know. It can save lives in emergencies when immediate action is necessary. By recognizing the signs of cardiac arrest, calling for professional help, and performing effective CPR, you can make a significant difference in someone's chance of survival.

Consider enrolling in a CPR course to gain hands-on experience and become more confident in your ability to respond effectively in emergencies. With CPR, you have the potential to be a hero and provide life-saving assistance when it's needed most.
