Which action would NOT help minimize the risk of gastric distention when ventilating an apneic patient with a bag-mask device?

Which action would NOT help minimize the risk of gastric distention when ventilating an apneic patient with a bag-mask device?

• A. delivering each breath over 1 second.
• B. ventilating the patient at the appropriate rate.
• C. increasing the amount of delivered tidal volume.
• D. ensuring the appropriate airway position.

Answer: (C)

Gastric distention during bag-mask ventilation occurs when air is forced into the stomach rather than the lungs, usually because of high airway pressures or delivering too much air at once. The best way to minimize this is to keep ventilation gentle and controlled while ensuring the airway is open and correctly aligned. Delivering each breath over about a second helps limit peak airway pressures, so less air is pushed into the stomach. Ventilating at an appropriate rate avoids both under- and over-ventilation, preventing unnecessary pressure buildup. Ensuring the airway is in the correct position reduces resistance and makes it easier to deliver effective breaths without needing to increase pressure. Increasing the amount of delivered tidal volume, on the other hand, would push more air into the stomach and worsen gastric distention, so it does not help reduce the risk.
