What is the first intervention recommended during a cardiac arrest?

• A. Automated External Defibrillator (AED)
• B. CPR
• C. Medication administration
• D. Establishing airway

Answer: (B)

During a cardiac arrest, the immediate priority is to restore effective circulation and oxygenation to the brain and other vital organs. Cardiopulmonary resuscitation (CPR) is the first intervention recommended because it combines chest compressions and rescue breaths to maintain blood flow and oxygen delivery when the heart has stopped pumping effectively.

Performing high-quality CPR helps to temporarily sustain life by providing some degree of blood flow to the vital organs until advanced medical interventions can be given or an automated external defibrillator (AED) can be deployed. While the use of an AED is crucial in the cardiac arrest scenario, it is not the first step; effective CPR should commence as soon as it is recognized that the person is in cardiac arrest.

Establishing an airway and administering medications are also important elements of advanced cardiac care, but these interventions follow the initiation of CPR. The early performance of CPR significantly encourages better outcomes for patients in cardiac arrest, making it the primary focus immediately after recognizing the emergency.
