In BLS airway obstruction for an unconscious patient, what is the recommended first action?

• A. Call for ALS
• B. Check for a pulse
• C. Begin CPR
• D. Transport immediately while continuing CPR

Answer: (C)

Start high-quality CPR immediately. In an unconscious patient who is not breathing normally, the priority is to maintain circulation and oxygen delivery to the brain and heart. Delaying CPR to check for a pulse can waste critical seconds and reduce the chance of survival. Begin chest compressions right away, and if you’re trained, provide ventilations as you continue CPR. If someone is available, have them activate EMS and get an AED as soon as possible; if you’re alone, start CPR and call for help while you begin compressions. The key is to not wait to verify a pulse before starting compressions.
