Final answer:
The priority interventions for a patient presenting with VF or pVT include immediate defibrillation and CPR. Defibrillation is done using external automated defibrillators (EADs) placed in public areas. CPR provides temporary oxygenation until a normal heart rhythm is restored.
Step-by-step explanation:
When a patient presents with ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT), the priority interventions include immediate defibrillation and cardiopulmonary resuscitation (CPR). Defibrillation is the process of delivering an electric shock to the heart to restore a normal heart rhythm. It is often done using external automated defibrillators (EADs), which are commonly placed in public areas. CPR should also be initiated to provide temporary oxygenation to the vital organs until a normal heart rhythm is restored.
