What should be done if bag-valve mask ventilation is ineffective?

When bag-valve mask ventilation is ineffective, the most appropriate action is to reposition the airway. This is essential because an inadequate seal, obstructions, or improper positioning can significantly impede effective ventilation. The head-tilt, chin-lift maneuver or jaw-thrust maneuver may be utilized to clear any obstructions and ensure the airway is open, allowing for better delivery of air into the lungs.

Ensuring that the airway is in the correct position minimizes resistance and maximizes the chances of successful ventilation with the bag-valve mask. This action can often resolve issues with ineffective bag-valve mask ventilation without needing to resort to other methods.

While increasing oxygen flow, switching to a different device, or calling for additional help may also be considered measures in certain situations, they do not directly address the most common causes of ineffective bag-valve mask ventilation. Prioritizing airway repositioning is a fundamental step in managing ventilation issues effectively.
