What oxygen percentage can a non-rebreather mask deliver?

0-40% O2
30-60% O2
80-95% O2
60-80% O2

The correct answer is: 80-95% O2

A non-rebreather mask is designed to deliver a high concentration of oxygen to patients in respiratory distress or with conditions requiring supplemental oxygen. This mask can provide an oxygen percentage ranging from approximately 80% to 95%. The high concentration is achieved by having a reservoir bag that allows the patient to inhale maximum oxygen while preventing the inhalation of room air, as the one-way valves on the mask prevent exhaled air from returning to the reservoir. This high level of oxygen delivery is crucial for patients who need immediate and effective oxygenation, such as those experiencing severe respiratory distress, carbon monoxide poisoning, or hypoxia. Understanding the functionality and appropriate application of the non-rebreather mask helps in delivering the right care in urgent situations.
