Sudden Cardiac Awareness Month

October Is Sudden Cardiac Arrest Awareness Month: Know the Facts, Save a Life

Every October, organizations across the country recognize Sudden Cardiac Arrest (SCA) Awareness Month to shine a spotlight on a critical public health issue that affects hundreds of thousands of people each year. Sudden cardiac arrest is a life-threatening emergency that can happen to anyone, anywhere, at any time. Understanding the signs, taking quick action, and being prepared can truly mean the difference between life and death.

What Is Sudden Cardiac Arrest?

Sudden cardiac arrest occurs when the heart suddenly and unexpectedly stops beating. Unlike a heart attack—which is caused by a blockage in blood flow to the heart—SCA is an electrical problem. The heart’s rhythm becomes chaotic, often due to ventricular fibrillation, and the heart cannot pump blood to the brain or other vital organs.

Without immediate intervention, a person in cardiac arrest will collapse, lose consciousness, and stop breathing. Brain damage can begin within 4–6 minutes, and survival rates decrease by 7–10% for every minute that passes without CPR and defibrillation.

Why Awareness Matters

Each year in the United States, more than 350,000 out-of-hospital cardiac arrests occur. Unfortunately, less than 10% of these individuals survive. But when bystanders step in with immediate CPR and early use of an Automated External Defibrillator (AED), survival rates can double or even triple.

Awareness campaigns during this month focus on educating the public, increasing access to AEDs, and encouraging more people to learn CPR. When communities are trained and equipped, lives are saved.

Recognizing the Signs of SCA

Sudden cardiac arrest can happen with little or no warning. Key signs include:

• Sudden collapse or loss of consciousness
  
  

• No normal breathing or only gasping
  
  

• No pulse or signs of circulation
  
  

If someone shows these signs, call 911 immediately, begin hands-only CPR, and use an AED as soon as one is available.

How You Can Make a Difference

You don’t need to be a medical professional to save a life. Here are a few ways you can help during Sudden Cardiac Arrest Awareness Month—and all year long:

• ✅ Learn CPR – Take a certified CPR course or a virtual training to gain confidence and skills.
  
  

• 🚑 Locate AEDs in your community – Familiarize yourself with AED locations at work, school, gyms, and public spaces.
  
  

• 🩺 Encourage preparedness – Advocate for CPR training and AED access at your workplace, school, or community center.
  
  

• 📢 Spread the word – Share educational materials and social media posts to help others learn about SCA.
  
  

A Call to Action

Sudden cardiac arrest doesn’t wait, and neither should we. By learning CPR, knowing how to use an AED, and raising awareness, each of us has the power to be the difference for someone’s tomorrow.

This October, take the time to get trained, talk to your community, and be prepared. A few minutes of your time could save a life.
