Cardiac Arrest: Signs, Symptoms, and How CPR Saves Lives

Cardiac arrest is a sudden, life-threatening emergency that can happen to anyone, anywhere, and at any time. When it strikes, every second matters. Knowing how to recognize the signs of cardiac arrest and respond with CPR can mean the difference between life and death. At Northern Nevada CPR, we provide American Heart Association–approved CPR and First Aid training in Reno and throughout Northern Nevada to prepare you for these critical moments.

What Is Cardiac Arrest?

Cardiac arrest occurs when the heart suddenly stops beating effectively, cutting off blood flow to the brain and vital organs. Unlike a heart attack—which is caused by blocked blood flow—cardiac arrest is often triggered by an electrical malfunction in the heart.

When this happens, the heart stops pumping, and the person collapses—often without warning. Without immediate CPR, brain damage can begin in 4–6 minutes, and death can occur within 10 minutes. That’s why learning how to recognize and respond is so important.

Key Signs of Cardiac Arrest

Here’s how to identify cardiac arrest quickly and confidently:

• Sudden Collapse – The person falls without warning and may lose consciousness.

• No Pulse – No detectable heartbeat (check the carotid artery if trained).

• No Breathing or Abnormal Breathing – The person isn’t breathing or is only gasping (agonal breathing).

• Unresponsiveness – No reaction to shouting, tapping, or shaking.

What Cardiac Arrest Is NOT

Cardiac arrest is often confused with other conditions:

• Seizures – A seizure may cause collapse, but the person usually resumes breathing and regains consciousness.

• Heart Attack – A heart attack often includes chest pain, sweating, and shortness of breath, but the person is usually awake and responsive.

• 
  

What to Do If You Suspect Cardiac Arrest

1. Call 911 Immediately – Get professional help on the way.

2. Start CPR – If the person is unresponsive and not breathing normally, push hard and fast in the center of the chest (100–120 compressions per minute). If trained, give 2 rescue breaths after every 30 compressions.

3. Use an AED (if available) – Automated External Defibrillators are designed for public use and give step-by-step instructions. Use one as soon as possible.

4. Don’t Stop Until Help Arrives – Continue CPR until the person wakes up, an AED advises you to stop, or emergency responders take over.
