Question

what is likely to cause air to enter the victims stomach( gastric inflation) during bag mask ventilation?

Answer 1

Several factors can cause air to enter the victim's stomach during bag mask ventilation, including inadequate mask seal, excessive force during ventilation, and an open esophageal sphincter.

Step-by-step explanation:

During bag mask ventilation, air can enter the victim's stomach, causing gastric inflation, due to several factors:

1. Inadequate mask seal: If the mask does not fit tightly on the victim's face, air can leak into the stomach instead of being directed to the lungs. This can happen if the mask is the wrong size or if it is not applied properly.
2. Excessive force during ventilation: If too much force is applied while squeezing the bag, it can push air past the epiglottis and into the esophagus and stomach instead of the trachea.
3. Esophageal opening not closed: If the esophageal opening (esophageal sphincter) does not close properly, air can enter the stomach during ventilation.

It is important to ensure a proper mask seal, use appropriate ventilation technique, and check for any obstructions or malfunctions to prevent gastric inflation during bag mask ventilation.
