Oxygen Delivery Devices

Low Flow Devices

 Nasal Cannula: 1-2 L/min = 24-28% O2,

3-4 L/min = 32-36% O2, 5-6 L/min = 40-

44% O2 (humidify if >4 L/min).

 Simple Face Mask: 40-60% O2.

 Partial Rebreather Mask: 40-70% O2 at

≥10 L/min.

 Non-Rebreather Mask: 60-80% O2 at ≥10

L/min.

High Flow Devices

 Venturi Mask: 24-60% O2 at 4-12 L/min.

Emergency Device

 Bag Valve Mask: delivers positive

pressure at up to 90% O2 @15 L/min
