  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%

      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
