How can gastric distention during ventilation be reduced?

• A. The patient is ventilated quickly with small volumes of air
• B. The patient is ventilated slowly with large volumes of oxygen
• C. The patient is given supplemental oxygen before ventilation
• D. The patient is positioned upright during ventilation

Answer: (B)

To effectively reduce gastric distention during ventilation, it is essential to focus on the technique of delivering breaths. Ventilating slowly with large volumes can lead to less air entering the stomach compared to rapid, forceful breaths. When positive pressure is applied too quickly, it can force air into the stomach rather than just the lungs, causing distention. By taking a slower approach when delivering larger volumes, the overall pressure and flow of air can be moderated, allowing better inflation of the lungs and reducing the likelihood of air entering the gastrointestinal tract. This way, the focus is on providing adequate ventilation while minimizing the risk of gastric inflation. If the patient were ventilated too quickly or with too much pressure, as seen in the other options, this could increase the risk of gastric distention. Proper technique thus not only enhances patient comfort but also significantly improves ventilation efficiency and safety.
