C) "Non-rebreathing" mask
D) Venturi mask
B
Feedback:
The partial-rebreathing mask can achieve oxygen concentrations between 60% and 90%, with a suggested flow rate of between 8 and 11 LPM. The simple mask is a low-flow device that provides an oxygen concentration in the range of 40% to 60%, with a flow of 6 to 10 LPM. The non-rebreathing mask can provide oxygen in the 90% to 100% range at a suggested flow rate of 12 LPM. Venturi masks offer specific oxygen concentrations ranging from 24% to 50% that match specific adapters for flow rates of 4, 6, or 8 LPM.
