If a patient is unresponsive on approach, which component is checked first?

If a patient is unresponsive on approach, which component is checked first?

• A. Circulation
• B. Airway
• C. Breathing
• D. CAB it flips when you have unconscious patients

Answer: (B)

Opening the airway is the first priority when you approach an unresponsive patient. If the airway is blocked or compromised, oxygen can’t reach the lungs, brain, or other vital organs no matter what you do next. So you first ensure the airway is clear and open—use the head-tilt/chin-lift unless a neck spine injury is suspected, in which case a jaw-thrust is safer. After the airway is open, quickly assess breathing and, based on that, provide ventilation if needed. Only then do you address circulation (compressions) if there’s no pulse or support breathing if there is a pulse but no breathing. Keeping the airway clear first prevents rapid hypoxia and sets up successful subsequent interventions.
