Quizplus · Accepted Answer

The nonrebreather mask is the best device for delivering high-concentration oxygen to a breathing patient as it has a reservoir bag that can be filled with oxygen, which is delivered to the patient during inhalation. The one-way valve prevents exhalation into the reservoir bag, thus preventing the patient from rebreathing exhaled air. This results in a high concentration of oxygen delivery to the patient.
