The Basics

What is CPR?

CPR is a hands-on emergency skill that keeps blood and oxygen flowing when the heart stops. It acts as a temporary “manual pump” to protect the brain and vital organs until medical help arrives.

Cardiac arrest isn’t something distant or rare; it could happen at a school, at home, at the play ground, or to someone we love, at any moment. Being prepared and ready could help save a life one day.

Each minute saves lives. Mortality increases by 10% each minute without proper CPR. Average response time for EMS to arrive is 7 minutes. OHCA Mortality is 80-90%. By learning CPR, one can be prepared and jump in to help well before EMS arrives and help increase survival significantly.

CPR should be started immediately when someone is unresponsive and not breathing normally (not breathing or only gasping). In cardiac arrest, the heart can’t pump blood effectively, so CPR keeps oxygen flowing until a defibrillator or EMS arrives.

Aim for 100–120 compressions per minute—the rhythm is fast, steady, and lifesaving. Think of songs like “Stayin’ Alive” or “Stronger” to keep the pace.

No more than 10 seconds. If you’re unsure or think you see only gasping, start CPR. Every second matters.

Everyone—students, athletes, adults, anyone. Cardiac arrest doesn’t wait for age, experience, or training level. The best responder is always the person who knows what to do.

Absolutely. Teens often perform CPR as well as adults, and sometimes even better because they respond faster and hesitate less.

The heart suddenly stops pumping blood effectively. Without oxygen, the brain and organs begin shutting down within seconds, which is why fast action matters so much
