Which low-flow oxygen delivery system provides the highest oxygen level to the client?
A. Partial rebreather mask
B. Nonrebreather mask
C. Simple face mask
D. Nasal cannula
B
The nonrebreather mask has a one-way valve between the mask and the reservoir and two flaps over the exhalation ports. The valve allows the client to draw all needed oxygen from the reser-voir bag, and the flaps prevent room air from entering through the exhalation ports. During ex-halation, air leaves through these exhalation ports while the one-way valve prevents exhaled air from re-entering the reservoir bag. A nonrebreather mask provides the highest oxygen level of the low-flow systems and can deliver an FIO2 greater than 90%, depending on the client's breathing pattern.
