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% Nick Mark MD @nickmmark #Mask #Oxygen #Delivery #Devices #management #pulmonary #criticalcare
