In the context of a cardiac event, immediate action is crucial for increasing the chances of survival. Starting cardiopulmonary resuscitation (CPR) within 3-5 minutes is essential because it helps maintain blood flow to vital organs, particularly the brain and heart, until professional medical personnel can take over. CPR involves a combination of chest compressions and rescue breaths, which facilitates oxygenation and circulation. This action can buy critical time, minimizing brain damage and increasing the likelihood of successful resuscitation.

While applying an Automated External Defibrillator (AED) is also a critical step that should follow quickly after CPR begins, the immediate focus is on providing chest compressions as soon as recognizing a cardiac event. Professional medical treatment and the patient regaining consciousness are goals, but they come after initiating CPR and using the AED if necessary. The survival chances dramatically decrease with each passing minute without CPR or defibrillation, emphasizing the importance of starting CPR immediately.
