What is a potential risk of using a non-rebreather mask incorrectly?

Using a non-rebreather mask incorrectly can lead to increased carbon dioxide levels in the patient. This mask is designed to deliver a high concentration of oxygen while preventing exhaled carbon dioxide from re-entering the mask. If the mask does not fit properly or if the one-way valves are obstructed or malfunctioning, exhaled carbon dioxide can accumulate in the mask, leading to the patient inhaling more carbon dioxide instead of pure oxygen.

This situation can be particularly dangerous for patients who are already struggling with respiratory issues, as elevated levels of carbon dioxide can increase the risk of respiratory acidosis and lead to potentially severe complications. Proper fitting and maintenance of the mask and its valves are essential for ensuring that the patient receives the intended benefits of oxygen therapy while minimizing the risk of elevated carbon dioxide levels.

Other options, while they may be considerations in different contexts, do not directly relate to the specific impact of incorrect non-rebreather mask usage on carbon dioxide levels, making the focus on increased carbon dioxide levels particularly relevant.
