    0.8-1.2 sec
  6. PIP
    ~15cmH2O
  7. PEEP
    5-10cmH20
  8. Sensitivity
    • -0.5 - -2 cmH2O
    • 1-3 LPM
  9. FiO2

    moderate
    severe
    • 60-79
    • 40-59
    • <40
  16. calculate pH
    pH= 6.1 + log [hco3/(paco2 x 0.03)]
  17. O2 content

  18. alveolar air PaO2
    [(PB-47)(FiO2)] - PaCO2(1.25)
  19. desired F
    (Known F x known PaCO2)/ desired PaCO2
  20. desired Vt
    (known Vt x known PaCO2)/ desired PaCO2
  21. TCT
    • total cycle time
    • 60/F or Ti + Te
  22. Ti =
    Vt/inspiratory flow (Vi)
  23. CO2 transport

    3 ways
    • as HCO3 (70%)
    • as carbamenohemoglobin (23%)
    • in plasma
  24. desired FIO2
    desired PaO2 x known FIO2/ known PaO2
