How long should you deliver effective PPV before moving on to other interventions?

• A. 60 seconds
• B. 30 seconds
• C. 5 seconds
• D. 90 seconds

Answer: (B)

Focusing on a quick, practical check of ventilation is the idea here. Giving effective PPV for about 30 seconds lets you confirm that your breaths are making the chest rise, you’re delivering an adequate tidal volume, and there’s no problematic air entry. It’s long enough to identify issues with seal, airway position, or need for an alternative airway, but short enough not to pull you away from other critical steps like chest compressions or further interventions.

If you see good chest rise and signs of adequate ventilation within that window, you can move on with the rest of the resuscitation plan. If ventilation isn’t effective, you should adjust technique (reposition the head, improve the mask seal, consider airway adjuncts) or switch to a different airway strategy.

Choosing a longer duration (60 or 90 seconds) would unnecessarily delay other life-saving actions, while a very short window (5 seconds) isn’t enough to judge effectiveness. Hence, 30 seconds is the best balance.
