What is a recommended first step after witnessing a cardiac arrest?

The recommended first step after witnessing a cardiac arrest is to call for emergency assistance. This step is crucial because it ensures that professional help is on the way while you take further action. Cardiac arrest is a time-sensitive condition where the heart is no longer effectively pumping blood to the body, particularly to the brain and other vital organs. Every moment counts, as brain damage can occur within minutes without oxygen-rich blood.

Calling for emergency assistance alerts trained responders who can provide advanced life support and transport the patient to a medical facility. While performing CPR is essential and should happen as soon as possible, it is critical to have emergency services on their way simultaneously. This dual action maximizes the chances of survival for the individual experiencing cardiac arrest.
