What should you do if you see someone collapse and they are unresponsive?

When someone collapses and is unresponsive, the immediate and most critical action is to call 911 and start CPR. This is because an unresponsive individual may be experiencing a cardiac arrest, where their heart is not effectively pumping blood to their vital organs.

Calling emergency services promptly ensures that professional help is on the way while you begin life-saving measures. Starting CPR immediately is vital because it helps maintain blood flow to the brain and other organs, increasing the chances of survival until advanced medical care arrives.

Performing CPR on an unresponsive person can significantly improve their outcome, as it can prevent brain damage and increase the likelihood of a full recovery if initiated quickly. It's important to start CPR as soon as possible rather than waiting to check for a pulse or assessing other conditions, which can waste precious time in a critical situation.
