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