What is Compression Only CPR?

Compression-only CPR, often referred to as hands-only CPR, is a simplified approach to cardiopulmonary resuscitation (CPR) that involves performing continuous chest compressions without rescue breaths. This method was developed to make CPR more accessible to bystanders, enabling more people to respond quickly and confidently in emergencies. Compression-only CPR focuses solely on maintaining circulation of oxygen-rich blood to the brain and other vital organs until professional medical assistance arrives or the heart is restarted.

Unlike conventional CPR, which alternates between chest compressions and rescue breaths, compression-only CPR removes the complexity of providing ventilation. This straightforward technique ensures that anyone—trained or untrained—can provide life-saving support in situations where immediate action is critical.

This guide will explore the importance of compression-only CPR, when to use it, how to perform it, and why training in CPR remains essential for everyone.

Introduction

Cardiopulmonary resuscitation (CPR) is a lifesaving technique used to restore blood circulation and breathing in individuals who have stopped breathing or whose heart has stopped beating. Compression-only CPR, also known as hands-only CPR, is a simplified version of this technique that involves performing chest compressions without rescue breaths. This method is particularly recommended in situations where a person is experiencing sudden cardiac arrest and is not breathing. By focusing solely on chest compressions, hands-only CPR ensures that oxygen-rich blood continues to circulate to vital organs, buying crucial time until professional medical help arrives. This approach makes it easier for bystanders to take immediate action, even if they are untrained, thereby increasing the chances of survival in emergency situations.

Why is Compression-Only CPR Important?

1. Cardiac Arrest Requires Immediate Intervention

Cardiac arrest occurs suddenly and often without warning. When the heart stops pumping effectively, blood flow to the brain, lungs, and other vital organs ceases. Without intervention:

• Brain damage begins within 4-6 minutes due to oxygen deprivation.

• Death can occur within 8-10 minutes.

Compression-only CPR provides a vital bridge by manually pumping oxygenated blood to sustain organ function until advanced life support is available.

2. Proven Effectiveness

Research shows that chest compression only CPR is just as effective as traditional CPR in the early minutes of sudden cardiac arrest in adults. The focus on chest compressions ensures consistent circulation of oxygen already present in the bloodstream, improving survival rates.

3. Removes Barriers to Action

Many bystanders hesitate to perform traditional CPR due to fear of incorrectly delivering rescue breaths, concerns about hygiene, or lack of training. Compression-only CPR eliminates these barriers, empowering more people to take immediate action.

4. Simplicity for Untrained Responders

By focusing on chest compressions alone, compression-only CPR simplifies the process, making it easier for individuals without formal training to step in and help during an emergency.

5. Adaptability During Health Crises

In situations like the COVID-19 pandemic or other infectious disease outbreaks, compression-only CPR reduces close contact, minimizing the risk of disease transmission while still delivering life-saving care.

When to Use Compression-Only CPR

Compression-only CPR is ideal in several scenarios where traditional CPR may not be feasible:

1. Adult Sudden Cardiac Arrest (SCA)

For adults who collapse suddenly, oxygen already present in their blood can sustain vital organs for several minutes with proper circulation from chest compressions.

It is important to perform 30 chest compressions in such scenarios to ensure effective circulation, especially in cases of respiratory arrests.

2. Untrained Responders

• If you lack CPR training, performing compression-only CPR is simpler and more intuitive than combining compressions with rescue breaths.

3. Safety Concerns for the Responder

• Visible Bodily Fluids: Blood, vomit, or other contaminants may pose a risk to the responder.

• Lack of Protective Equipment: Without a face shield or mask, performing mouth-to-mouth can be unsafe.

4. Social Distancing or Health Concerns

• During infectious disease outbreaks, such as COVID-19, compression-only CPR allows for life-saving intervention while minimizing close contact.

When NOT to Use Compression-Only CPR

Compression-only CPR is not recommended for:

1. Children and Infants: Pediatric cardiac arrests often result from respiratory issues, requiring oxygen replenishment through rescue breaths.

2. Drowning Victims: Drowning victims lack adequate oxygen in their blood and need ventilation.

3. Drug Overdoses or Respiratory Arrest: In these cases, rescue breaths are critical to provide oxygen and address the underlying cause.

How to Perform Compression-Only CPR

Compression-only CPR is simple to perform, but correct technique is essential for effectiveness. Follow these steps:

1. Ensure the person is lying flat on their back on a firm surface.

2. Place the heel of one hand on the center of the chest, and your other hand on top of the first.

3. Use your body weight to help you administer compressions that are at least 2 inches deep and at a rate of 100-120 compressions per minute.

If you are alone, start chest compressions immediately and continue for about two minutes before calling for emergency help. It is crucial to begin chest compressions right away to maintain blood flow to vital organs.

Step 1: Assess the Situation

• Ensure Safety: Before approaching, check for hazards like traffic, fire, or unstable structures. Only proceed if it’s safe to do so.

• Check Responsiveness: Tap the victim’s shoulders and shout, “Are you okay?”

• Identify the Need for CPR: If the victim is unresponsive and not breathing or only gasping (agonal breathing), begin CPR immediately.

Step 2: Call Emergency Services

• Call 911 or Your Local Emergency Number: If alone, use speaker mode to call while performing CPR.

• Retrieve an AED: If available, instruct someone to locate an Automated External Defibrillator (AED). These devices are often found in public spaces like airports, gyms, and schools.

Step 3: Position the Victim

• Lay the victim flat on their back on a firm surface.

• Kneel beside their chest, positioning yourself at their side for effective compressions.

Step 4: Locate the Compression Point

• Place the heel of one hand on the center of the chest, over the lower half of the breastbone (sternum).

• Place your other hand on top, interlocking your fingers.

• Ensure your arms are straight, with your shoulders directly over your hands.

Step 5: Perform Continuous Chest Compressions

Push Hard and Fast:

• Perform chest compression by compressing the chest at least 2 inches deep for adults.

• Use your body weight to apply consistent pressure.

Allow Full Recoil:

• Let the chest return to its normal position after each compression, ensuring the heart can refill with blood.

Maintain the Correct Rhythm:

• Perform compressions at a rate of 100-120 per minute. Use a song like Stayin’ Alive to keep the proper pace.

Step 6: Do Not Stop

• Continue chest compressions without pausing until:

  • Emergency responders arrive.

  • An AED is available and ready for use.

  • You are physically unable to continue.

Effectiveness of Compression-Only CPR

Compression-only CPR is highly effective for adult cardiac arrests caused by sudden heart problems. Benefits include:

1. Ease of Use: Simplifies the process for untrained bystanders.

2. Encourages Action: Reduces hesitation to intervene in emergencies.

3. Maintains Blood Flow: Keeps oxygen-rich blood circulating to the brain and heart, increasing survival chances.

It is crucial to perform hands-only CPR in emergency situations, as bystander intervention significantly increases the chances of survival for out-of-hospital cardiac arrest victims.

Special Situations

ICDs, Pacemakers, and Recent Surgery

When a person with an implantable cardioverter-defibrillator (ICD) or pacemaker experiences cardiac arrest, it is crucial to perform CPR. These devices will not function properly if the heart has stopped beating, and CPR can help restore blood circulation and breathing. Similarly, if someone has recently undergone surgery, performing CPR remains essential in the event of cardiac arrest. However, it is important to be mindful of any medical devices or equipment attached to the person, such as a pacemaker or ICD. Take care to avoid damaging these devices while performing chest compressions. The primary goal is to maintain blood flow and oxygenation, which can be life-saving even in these special circumstances.

Concerns

One of the common concerns about performing CPR is the fear of liability or causing harm to the victim. However, it is important to remember that laws are in place to protect individuals who provide emergency assistance in good faith. These laws generally shield rescuers from repercussions as long as they act reasonably and within their level of training. Additionally, the benefits of performing CPR far outweigh the risks. Effective chest compressions can significantly increase the chances of survival, even if they result in minor injuries like broken ribs. The priority is to save a life, and taking immediate action with hands-only CPR can make a critical difference.

Importance of CPR Training and Certification

While compression-only CPR is straightforward, formal CPR training equips individuals with comprehensive skills, including when and how to incorporate rescue breaths. Benefits of training include:

1. Proper Techniques: Training ensures compressions are delivered with the correct depth, rate, and hand placement.

2. Traditional CPR Skills: Learn to perform full CPR with rescue breaths for cases where ventilation is critical.

3. AED Proficiency: CPR courses teach how to use AEDs effectively.

4. Regular Updates: Guidelines for CPR evolve; certification ensures you stay informed about best practices.
