In the event of cardiac arrest, what is the first action you should take?

In cases of cardiac arrest, the first critical action to take is to call for emergency medical services, such as 911. This step is essential because it ensures that professional help is on the way while you provide life-saving measures. Calling for help initiates the emergency response system, allowing first responders to arrive as quickly as possible to provide advanced care. It's also important to ensure that someone is specifically tasked with making this call to avoid delays in getting medical assistance.

Once emergency services have been contacted, the next steps can involve beginning compressions and other rescue techniques, but the priority is always to alert professionals because they can provide the necessary equipment and support that bystanders may lack. Starting immediate CPR, checking for a pulse, or providing rescue breaths may follow, but these actions should occur only after ensuring that help is en route.
