When used as a nonrebreather,the face mask with a reservoir bag delivers 60% to 90% oxygen at 15 L/min.The simple face mask delivers oxygen concentrations from 40% to 60% when set at 5 to 8 L/min.It is not used at 15 L/min.A Venturi mask delivers oxygen concentrations from 24% to 60% when set at 4 to 12 L/min.It is not used at 15 L/min.An oxygen tent is usually for pediatric use and delivers up to 50% oxygen concentration at 10 to 15 L/min.
