In cases of suspected cardiac arrest, what is the recommended first step?

In a situation where cardiac arrest is suspected, the initial and most critical step is to call emergency services. This is essential because immediate medical assistance is needed for the individual, and trained professionals can provide advanced care on the way to the scene. By calling emergency services first, you ensure that help is on the way while you address the immediate needs of the victim.

Following this action, it is important to check for breathing and assess the situation further. If the person is unresponsive and not breathing or only gasping, you would begin CPR, which includes chest compressions and potentially rescue breaths. However, without the first action of alerting emergency services, there will be no medical backup available to provide further assistance when needed, making it a critical first step in any cardiac emergency.
