Final answer:

A non-rebreather mask (NRB) is a medical device used to deliver high-flow oxygen to a patient. It is indicated for patients who require high levels of oxygen, such as those with acute respiratory failure or severe pneumonia.

Step-by-step explanation:

A non-rebreather mask (NRB) is a medical device used to deliver high-flow oxygen to a patient. It has a reservoir bag that holds oxygen, and one-way valves to prevent exhaled air from entering the mask. The FiO2 (fraction of inspired oxygen) delivered by the NRB is typically close to 100%, making it effective for patients with severe respiratory distress.

NRBs are indicated for patients who require high levels of oxygen, such as those with acute respiratory failure, severe pneumonia, or pulmonary edema. They are also used in emergency situations, such as cardiac arrest or trauma, to provide high-flow oxygen and prevent hypoxia.
