Low Flow OxygenAka: Low Oxygen Delivery, Nasal cannula, Face Tent, Face Shield, Simple Oxygen Mask
1. See Also 1. Oxygen Delivery 2. Nasal Cannula 1. Two short plastic nasal prongs 2. Delivers 25-45% FIO2 at 1-6 L/min flow 3. Delivers 4% Oxygen per liter flow 1. Flow 0 liters per minute: 21% (Room Air) 2. Flow 1 liters per minute: 25% 3. Flow 2 liters per minute: 29% 4. Flow 3 liters per minute: 33% 5. Flow 4 liters per minute: 37% 6. Flow 5 liters per minute: 41% 7. Flow 6 liters per minute: 45% 4. Flow rates >4 liters per minute irritates nasopharynx 5. Does not provide humidified oxygen 3. Face Tent/Shield 1. High-flow, soft plastic "bucket" over nose and mouth 2. Better tolerated than face mask 3. Delivers only 40% Oxygen at 10-15 liters per minute 4. Simple Oxygen Mask 1. In children use the Soft Vinyl Pediatric Mask 2. Poorly tolerated by infants and toddlers 3. Delivers 35-60% Oxygen at 6-10 L/min flow rates 1. Room air entrained during inspiration 2. Reduced Oxygen Concentration if: 1. High spontaneous inspiratory flow 2. Mask is loose 3. Oxygen flow into the mask is low
