How do compressions change once an advanced airway is placed?

• A. Compressions should be continuous with ventilations every 3 seconds
• B. Compressions should be paused between ventilation breaths
• C. Ventilations should be delayed to allow full chest recoil
• D. Ventilations should be given only with each third compression

Answer: (A)

With an advanced airway in place, the emphasis is on delivering continuous chest compressions while ventilations are given without interrupting those compressions. The airway allows breaths to be delivered through the tube while you keep the compression rate steady, so you don’t pause to ventilate in between pushes. This approach maintains coronary and cerebral perfusion pressures, which is why continuous compressions with a regular ventilation cadence is preferred. In practice, breaths are delivered at a fixed interval during ongoing CPR (for example, a breath every few seconds), rather than pausing to breathe between compression cycles. Pausing for breaths or delaying ventilation would interrupt perfusion and reduce effectiveness. Similarly, ventilating only with every third compression would still insert pauses and disrupt continuous compressions. So the best approach is to keep chest compressions continuous and deliver ventilations at a steady, ongoing interval through the airway.
