Compression-Only CPR: When and Why to Utilize It

In an emergency, every second counts. When someone collapses due to sudden cardiac arrest, your immediate action can mean the difference between life and death. Compression-only CPR is a method anyone can perform—even without prior medical training. But when is it the right approach, and why has it become widely accepted in many situations? 

What Is Compression-Only CPR?

Compression-only CPR involves chest compressions without mouth-to-mouth breaths. The goal is simple: keep blood flowing to vital organs by pushing hard and fast on the center of the chest. This method helps maintain circulation until emergency responders arrive with advanced care.

When Should You Use Compression-Only CPR?

Compression-only CPR is recommended for:

• Adult victims of sudden cardiac arrest

• Bystanders without formal CPR Training

• Situations where rescue breaths may feel uncomfortable or unsafe

It’s not suitable for infants, children, or cases involving drowning or drug overdose, where traditional CPR (with rescue breaths) is still important.

Why Does It Work?

When someone suffers sudden cardiac arrest, there is still oxygen in the blood for a few minutes. Chest compressions alone can move that oxygenated blood to the brain and heart. Studies have shown that compression-only CPR performed by bystanders can increase survival rates in certain adult cardiac emergencies.

Common Myths and Misunderstandings

Do I Need Certification to Help Someone?

No, Good Samaritan laws protect those who act in good faith. But proper training gives you confidence and skill to act quickly.

Isn’t Mouth-to-mouth Necessary?

Not always. For adult cardiac arrests outside of medical settings, chest compressions alone can be just as effective—especially in the first few critical minutes.

Can I Hurt Someone by Doing CPR?

Doing something is better than doing nothing. Compressions may cause injuries, but failing to act can result in death.
