Mask Oxygen Delivery Devices



Simple Mask aka Hudson's Mask:

 • Flow 6-10 LPM

 • FiO2 35-50%

Face Tent:

 • Face Tents are loose fitting & may be useful in people who do not tolerate a tight-fitting mask (e.g. facial trauma, recent surgery, etc)

 • Flow 10-15 LPM

 • FiO2 30-40%

Venturi Mask:

 • A venturi mask uses a small valve to mix oxygen ambient air to achieve desired Fi02. The venturi valves are color coded; each is sized to provide a different FiO2 for a specified flow rate:

 • Flow 2-15 LPM

 • FiO2 24-60%

Partial Rebreather:

 • The addition of an inflatable reservoir increases delivered oxygen.

 • Flow 10-15 LPM

 • FiO2 60-80%

Non-Rebreather (NRB)

 • Non-rebreather masks have two one-way valves over the exhalation ports. These permitting exhalation but maintain a higher FiO2.

 • Flow 10-15 LPM

 • FiO2 ~80%
