For nonshockable rhythms, when should placement of an advanced airway and capnography occur?

• A. Placement of advanced airway and capnography should be delayed until CPR has been provided for at least 2 minutes
• B. Capnography is unnecessary
• C. Capnography should be established before CPR begins
• D. Capnography and advanced airway should be established immediately

Answer: (A)

In nonshockable cardiac arrest, the priority is continuous high-quality chest compressions with as few interruptions as possible. Securing an advanced airway too early can create pauses in CPR, so the airway and capnography are typically addressed after some initial CPR has been delivered. The recommended timing is after about 2 minutes of ongoing CPR. At that point, you can place the advanced airway and connect capnography to confirm tube placement and to monitor ventilation and perfusion during resuscitation. Capnography is not unnecessary; it should be used once the airway is secured to verify correct placement and to help gauge CPR quality. Establishing capnography before CPR begins isn’t feasible, and trying to place an advanced airway immediately can disrupt chest compressions. So delaying until after two minutes of CPR reflects the balance between maintaining perfusion with continuous compressions and securing the airway with minimal interruption.
