In Basic Life Support, after life check, what is the first action?

• A. Chest Compressions
• B. Intubation and Ventilation
• C. Defibrillation
• D. Airway suction

Answer: (A)

The first action is to start chest compressions immediately. The goal is to restore circulating blood flow to the brain and heart without delay, because without perfusion, brain injury and death can occur within minutes regardless of oxygen in the lungs. Beginning compressions right away provides the best chance of maintaining vital organ perfusion while help is on the way and an AED is prepared. Defibrillation should be applied as soon as the AED is ready and indicates a shock, but it should not replace the initial chest compressions. Ventilation and advanced airway management are important, but delaying compressions for airway maneuvers or intubation compromises perfusion. If you’re trained, you can alternate breaths (e.g., 30 compressions to 2 breaths) without interrupting compressions for long, but the priority remains continuous chest compressions.
