What should you do if someone is in cardiac arrest?

In a situation where someone is in cardiac arrest, the most critical and effective action to take is to immediately call for help, start CPR, and use an AED (automated external defibrillator) if one is available. This prompt response is essential for increasing the chances of survival.

Cardiac arrest occurs when the heart stops beating effectively, which leads to a lack of blood flow to the brain and other vital organs. Starting CPR provides artificial circulation by compressing the chest to keep blood flowing, which can sustain vital organs until emergency medical services arrive. The use of an AED adds an important step; it delivers an electric shock to the heart, which can restore a normal rhythm.

Providing comfort and waiting for help offers no benefit in a cardiac arrest situation, as immediate intervention is necessary. Checking for responsiveness without acting can delay crucial care, and giving water does not address the medical emergency at hand. Prompt action is vital in these scenarios, making the correct response clear and crucial for the affected individual’s survival.
