What is CPR?

Cardiopulmonary Resuscitation (CPR) is a life-saving emergency procedure performed when a person's breathing or heartbeat has stopped. This critical intervention is designed to maintain blood flow and oxygenation to the brain and other vital organs, buying precious time until advanced medical care can be administered. CPR is not a cure, but rather a bridge to definitive treatment for conditions like cardiac arrest.

When Should CPR Be Performed?

CPR is indicated in situations where an individual is unresponsive, not breathing normally, and shows no signs of circulation (like normal breathing or movement). This typically occurs in cases of sudden cardiac arrest (SCA), which can be caused by heart attack, drowning, choking, electrocution, drug overdose, or severe trauma. Recognizing the signs of cardiac arrest is the first step towards initiating CPR.

Recognizing Cardiac Arrest

Key signs of cardiac arrest include:

• Unresponsiveness: The person does not respond to shouting or gentle shaking.
• Absence of Breathing: The person is not breathing or is only gasping irregularly (agonal breaths).
• No Signs of Circulation: The person is not coughing or moving.

It's important to differentiate cardiac arrest from other emergencies. For example, if someone is conscious and breathing, CPR is not needed. If someone is choking, the recommended first step is to perform the Heimlich maneuver.

Types of CPR

There are two main types of CPR:

Conventional CPR (Chest Compressions and Rescue Breaths)

This is the traditional form of CPR, involving a cycle of chest compressions and rescue breaths. It is typically performed by individuals who have received formal training and are comfortable with providing rescue breaths. The standard ratio for adults is 30 compressions followed by 2 rescue breaths.

Hands-Only CPR

Recommended for untrained bystanders or those who are unwilling or unable to perform rescue breaths, Hands-Only CPR focuses solely on high-quality chest compressions. This method has been shown to be as effective as conventional CPR for adults experiencing cardiac arrest, especially in the first few minutes. The American Heart Association recommends continuous chest compressions at a rate of 100-120 per minute.

How to Perform CPR (Adults)

If you encounter an adult who is unresponsive and not breathing normally:

1. Check for Safety: Ensure the scene is safe for you and the victim.
2. Call for Help: Immediately call emergency services (e.g., 911 in the US) or have someone else call. If an AED (Automated External Defibrillator) is available, send someone to retrieve it.
3. Check for Responsiveness and Breathing: Tap the person's shoulder and shout, "Are you okay?" Look for chest rise and fall.
4. Begin Chest Compressions:
• Kneel beside the person.
• Place the heel of one hand on the center of the chest, between the nipples.
• Place the heel of your other hand on top of the first hand.
• Interlock your fingers and keep them off the chest.
• Position yourself so your shoulders are directly over your hands.
• Keep your arms straight and use your body weight to push hard and fast.
• Compress the chest at least 2 inches (5 cm) deep.
• Compress at a rate of 100-120 compressions per minute (think of the beat of the song "Stayin' Alive").
• Allow the chest to recoil completely between compressions.
• Continue compressions without interruption until an AED arrives and is ready to use, or professional rescuers take over.
5. If Trained and Willing, Give Rescue Breaths:
• After 30 compressions, open the airway by tilting the head back and lifting the chin.
• Pinch the person's nose shut.
• Make a complete seal over the person's mouth with your mouth.
• Give 2 rescue breaths, each lasting about 1 second, and watch for chest rise.
• If the chest does not rise, reposition the airway and try again.
• Immediately resume chest compressions.
6. Use an AED if Available: Follow the voice prompts of the AED. It will analyze the heart rhythm and advise if a shock is needed.

CPR for Children and Infants

CPR techniques are modified for children (age 1 year to puberty) and infants (under 1 year).

Children:

• Use one or two hands for chest compressions, depending on the child's size.
• Compress the chest about 2 inches (5 cm) deep.
• The compression-to-breath ratio is still 30:2 for a single rescuer, or 15:2 for two rescuers.

Infants:

• Use two fingers (or two thumbs encircling the chest for two rescuers) to compress the chest.
• Compress the chest about 1.5 inches (4 cm) deep.
• The compression-to-breath ratio is 30:2 for a single rescuer, or 15:2 for two rescuers.
• Be careful not to tilt the infant's head too far back.

Importance of CPR Training

While Hands-Only CPR can be performed by anyone, formal CPR training provides the knowledge and confidence to perform both compressions and rescue breaths effectively. Certified courses teach proper techniques, how to use an AED, and how to handle different age groups. Organizations like the American Heart Association and the Red Cross offer these vital training programs. Learning CPR is a skill that could save a life.
