Tuller Revisited

1. Specific Examples
   • case C
     • data
       • pH = 7.55 units
       • PaCO2 = 27 mm Hg
       • [HCO3-] = 23 mmol/L
       • PaO2 = 104 mm Hg
       • SaO2 = 98%
     • diagnosis
       • 1ø respiratory alkalosis
       • no compensation whatsoever ("get the bag out!")

   • case D
     • data
       • pH = 7.30 units
       • PaCO2 = 34 mm Hg
       • [HCO3-] = 24 mmol/L
     • diagnosis
       • data incompatibility ("get the technician out?)

2. Lessons Learned
   • when in doubt, do not guess, but obtain another arterial blood sample for analysis
   • never discredit the importance of acquiring an accurate patient history
