  • Non-Rebreathing Mask with reservoir
  1. Delivers only 60-70% Oxygen at 15 L/min
    1. Previously described as delivering 95% FIO2 (leakage around mask prevents this)
    2. Standard anesthesia masks have tighter seal and achieve closer to 95% FIO2
    3. Increasing flow above 15 L/min if regulator allows can achieve closer to 90% FIO2
      1. Alternatively concurrently apply Nasal Cannula at 15 lpm with Non-Rebreather Mask
  2. Two valves added to rebreathing mask prevents:
    1. Entrainment of room air during inspiration
    2. Retention of exhaled gases during expiration
  • Preparations
  • Oxygen Hood
  1. Clear plastic shell encompasses the baby's head
  2. Well tolerated by infants
  3. Size of hood limits use to younger than age 1 year
  4. Allows easy access to chest, trunk, and extremities
  5. Allows control of Oxygen Delivery
    1. Oxygen concentration
    2. Inspired oxygen Temperature and humidity
  6. Delivers 80-90% oxygen at 10-15 liter per minute
