Question

You are teaching a group of firefighters who are in class to become Emergency Medical Responders. The topic is artificial ventilation with the bag-valve mask (BVM). Which one of the following points related to using the BVM should you emphasize?

a. Maintaining a good mask-to-face seal is difficult.
b. The BVM is useless unless it is hooked to supplemental oxygen.
c. It is better to ventilate too quickly as opposed to too slowly.
d. The bag must be fully squeezed in order to give a proper amount of volume with each breath.

Answer 1

The correct answer is option A

A. Maintaining a good mask-to-face seal is difficult.

Explanation: this is because of the relationship between the mask size and the mask seal. A wrong size of mask will hinder a good seal causing air to escape through the edges making it difficult to breath.
