When is passive insufflation indicated?

• A. The first 6 minutes of any adult cardiac arrest with cardiac etiology
• B. The first 10 minutes of any adult cardiac arrest
• C. The first 12 minutes
• D. The first 8 minutes (4 cycles) of any adult cardiac arrest with cardiac etiology

Answer: (D)

The question tests when you use passive insufflation during CPR in an adult with cardiac-etiology arrest. The technique is intended to provide ventilation without interrupting chest compressions, and it’s recommended only during the initial phase of resuscitation—the first four cycles, which is about eight minutes. This window aligns with keeping high-quality, continuous chest compressions while still delivering some oxygen to the lungs. After this initial period, you transition to standard ventilation methods (such as bag-valve mask or an advanced airway) to ensure adequate ventilation and tidal volume. The other time frames exceed or fall short of this early window, which is why they aren’t the indicated period for passive insufflation.
