Airway & VentilationCâu 3 / 100

a.2 to 4 L/min
b.4 to 6 L/min
c.10 to 15 L/min
d.1 to 2 L/min

A nonrebreather mask requires 10 to 15 L/min to keep the reservoir bag inflated and deliver a high oxygen concentration (roughly 80 to 90 percent). Lower flow rates fail to keep the reservoir filled between breaths.
