  1. nasal cannula
    • 1 - 6 LPM
    • FIO2 24-44
  2. simple mask
    • 5 - 12 LPM
    • 35 - 50 FIO2
  3. reservoir cannula
    • 1/4 - 4 LPM
    • 22 - 35 FIO2
  4. trans-trachael catheter
    • 1/4 - 4 LPM
    • 22-35 FIO2
  5. partial rebreather
    • 6 - 10 LPM
    • 35-60 FIO2
  6. non-rebreather
    • 6 - 10
    • 55-50 FIO2
    • one flap may be removed to prevent accident suffocation, this will provide slightly less FIO2
  7. AEM (air entrainment mask or venturi mask)
    • LPM determined by percentage of oxygen to be delivered.
    • 24 - 50 FIO2 (varies with back pressure)
    • LPM / FIO2
    • 2 - 24%
    • 4 - 28%
    • 6 - 31%
    • 8 - 35%
    • 8 - 40%
    • 12 - 50%
  8. low flow
    • less than 8 LPM
    • all basic O2 devices are low flow with variable FIO2 excepe AEM
  9. When should humidity be provided?
    When flow is greater than 4 LPM
  10. O2 concentration
    • low - less than 35%
    • moderate - 35-60%
    • high - greater than 60%
  11. High flow vs. low flow devices
    • High flow devices meets and exceeds the patients demands.
    • Low flow devices supplements with room air
  12. hypoxemia
    • less than 60 torr PaO2
    • less than 90% SaO2
    • PaO2 ranges:
    • normal 80-100%
    • mild 60-79%
    • moderate 59-40%
    • severe less than 40%
  13. respiratory rate
    • normal 12-20 breaths per minute
    • if greater than 25; patient needs a high flow system
    • rate greater than 35 is a critical value and indicates need for mechanical ventilation
  14. Patient's PaO2 norms per age of patient
    age 60 PaO2 less than 80 is normal
