What is one potential risk of using a non-rebreather mask for oxygen delivery?

Using a non-rebreather mask for oxygen delivery carries several important considerations, one of which is the risk of suffocation if not properly monitored. This type of mask is designed to deliver high concentrations of oxygen to a patient while preventing the inhalation of carbon dioxide that may be present in the air. It does this by using a one-way valve system that allows oxygen to flow in but limits the breathing of air from the environment.

If the mask's reservoir bag is not properly filled or if the flow of oxygen is insufficient, the patient may not receive enough oxygen. More critically, if the mask does not allow for exhalation or if there is a disruption in the oxygen supply, the patient could be at risk of asphyxiation due to carbon dioxide buildup. This risk is particularly serious in patients with altered mental status or respiratory drive, where monitoring and ensuring proper function of the mask becomes crucial.

Monitoring the patient ensures that they are receiving adequate oxygen and can also alert caregivers to any potential issues before they become critical.
