During CPR for an adult patient with a compromised airway, which ventilation approach is recommended?

• A. Ventilate him once when CPR stops after 30 compressions
• B. Use a two person ventilation technique
• C. Use a BVM that can refill in 3 seconds
• D. Ventilate every 15 seconds with BVM

Answer: (B)

During CPR, delivering effective breaths while keeping chest compressions going is essential, especially when the airway is compromised. A two-person bag-valve-mask ventilation approach allows one rescuer to maintain a tight mask seal and deliver breaths, while the other performs chest compressions. This teamwork reduces interruptions, ensures adequate tidal volumes with each breath, and improves oxygen delivery and overall perfusion during resuscitation. Waiting to ventilate after a cycle of compressions or trying to breathe at fixed, inappropriate intervals can disrupt the rhythm of CPR and lower effectiveness. While a fast-refilling BVM helps, the key improvement comes from having a second rescuer manage ventilation to maintain a good seal and consistent breaths.
