For nonshockable rhythms, which treatment approach is recommended?

• A. Advance airway placement should be delayed until CPR has been performed for at least 2 minutes
• B. Defibrillate immediately
• C. Place an advanced airway first, before CPR
• D. Epinephrine should be administered as early as possible, with placement of advanced airway and capnography delayed until CPR has been provided for at least 2 minutes

Answer: (D)

In nonshockable cardiac arrest, the priority is to maximize blood flow to the brain and heart with continuous, high-quality CPR, while providing vasopressor support early. Defibrillation isn’t indicated for asystole or pulseless electrical activity, so trying to shock won’t help. The best approach is to begin CPR immediately and administer epinephrine as soon as possible, rather than delaying CPR for airway work. Advanced airway placement and capnography should be considered after about 2 minutes of sustained CPR so that chest compressions aren’t interrupted, but you still have a way to monitor airway placement and CPR quality. This combination—early epinephrine with CPR kept as the ongoing priority and airway procedures deferred until after initial CPR—aligns with guidelines for nonshockable rhythms.
