Airway & VentilationQuestion 20 of 100
What oxygen flow rate is typically used with a bag-valve mask to maximize delivered oxygen concentration?
a.2 L/min
b.4 L/min
c.6 L/min
d.15 L/min
Explanation
A BVM connected to an oxygen reservoir at 15 L/min can deliver nearly 100 percent oxygen. Adequate flow keeps the reservoir bag full so each ventilation delivers high-concentration oxygen.
