When should you call 911 during an emergency?

Calling 911 during an emergency is critical when a person is unresponsive and not breathing. This situation indicates a possible life-threatening condition, such as a cardiac arrest or severe respiratory distress, where immediate medical assistance is necessary.

When someone is unresponsive, it means they cannot be awakened or do not respond to stimuli, which is a serious concern. The absence of breathing is equally alarming, as it suggests that the person's heart may no longer be functioning properly, putting them at risk of death or severe brain injury if help is not rendered promptly.

In such scenarios, calling 911 ensures that emergency medical services can provide immediate intervention, such as CPR or advanced life support, which are vital to increasing the individual's chances of survival. The urgency of the situation warrants quick action, highlighting the importance of knowing when to contact emergency services.
