Signs of Cardiac Arrest Caregivers Should Never Ignore

Cardiac arrest can happen suddenly, particularly among older adults or individuals with heart disease. Caregivers must be able to recognize the warning signs quickly — because acting fast can mean the difference between life and death.

Sudden Collapse

One of the most common signs of cardiac arrest is sudden collapse without warning. The person may fall to the ground without being able to catch themselves.

Unresponsiveness

If the person does not respond when tapped firmly on the shoulder or spoken to loudly, they may be unconscious. Unresponsiveness is a key sign that something is seriously wrong.

Abnormal or Absent Breathing

People experiencing cardiac arrest may gasp irregularly or stop breathing entirely. Normal breathing should be steady and even — anything else warrants immediate action.

What to Do Immediately

If someone collapses and is not breathing normally: call 911 right away, begin chest compressions, and continue CPR until emergency responders arrive.

Training Prepares You to Act

Knowing what to look for is only part of being prepared. CPR training gives caregivers the hands-on practice they need to respond with confidence. Learn more about our training programs or request on-site training for your organization.
