What is the best technique to avoid air entering the stomach during bag-mask ventilation?

Quickly squeeze the bag to inflate the lungs

Use a high pressure while squeezing the bag

Squeeze the bag slowly and release when observing chest rise

The best technique to avoid air entering the stomach during bag-mask ventilation is to squeeze the bag slowly and release when observing chest rise. This approach is effective because it allows for controlled ventilation, ensuring that air is delivered into the lungs rather than forcing it into the stomach.

By squeezing the bag at a slow and steady pace, the provider can monitor the patient's chest movement. Observing the chest rise indicates that air is entering the lungs appropriately. This method helps to prevent excessive pressure that can lead to positive pressure entering the esophagus and, subsequently, the stomach. Additionally, slow squeezing reduces the risk of causing barotrauma to the lungs.

Taking the time to perform this technique with care ensures that ventilations are effective while minimizing complications associated with improper bag-mask ventilation. It's essential to maintain proper mask fit and seal while giving breaths to ensure the best outcomes.

Maintain a tight seal and push hard on the bag
