What is the recommended action following the call for emergency services if someone is in cardiac arrest?

Starting CPR immediately after calling for emergency services is vital in a cardiac arrest situation because it helps to maintain blood circulation to vital organs, particularly the brain and heart. Every minute that passes without CPR significantly decreases the chances of survival, so the emphasis is on initiating chest compressions without delay.

While waiting for help is important, it should not come at the expense of immediate action. Checking for a pulse or administering medication may not be feasible or necessary before starting CPR. In the case of cardiac arrest, time is critical; thus, the priority is to provide effective chest compressions as quickly as possible to stabilize the individual until professional medical assistance arrives.
