  1. 1ABG Analyzers
    Directly measures [blank_start]PCO2[blank_end] - Severinghaus, [blank_start]PO2[blank_end] - Clark, pH - [blank_start]Sanz[blank_end]
    HCO3, SaO2 and other values are calculated
    Formula for read out: (Barometric Pressure - [blank_start]47[blank_end]) x Fractional Concentration of [blank_start]gas[blank_end]
    1. APCO2
    2. BPO2
    3. CSanz
    4. D47
    5. Egas
  2. 2Severinhaus Electrode
    Measures [blank_start]PCO2[blank_end]
    [blank_start]Glass[blank_end] electrode in [blank_start]lucite[blank_end] jacket
    Includes nylon spacer and [blank_start]teflon[blank_end] membrane
    1. APCO2
    2. BGlass
    3. Clucite
    4. Dteflon
  3. 3PCO2 Calibration:
    Cylinders containing known concentrations of gas:
    Low: [blank_start]5[blank_end]% balance
    High: [blank_start]10[blank_end]% slope
    1. A5
    2. B10
  4. 4Clark Electrode
    Measures [blank_start]PO2[blank_end]
    Platinum cathode, silver-silver chloride anode, polypropolene membrane (gas [blank_start]permeable[blank_end])
    Using [blank_start]mylar[blank_end] membrane results in insufficient O2 diffusion
    Cleaning top with [blank_start]pumice[blank_end] periodically to clean [blank_start]protein[blank_end]
    1. APO2
    2. Bpermeable
    3. Cmylar
    4. Dpumice
    5. Eprotein
  5. 5PO2 Calibration:
    Cylinders containing known concentrations of gas:
    Low: [blank_start]0[blank_end]% balance
    High: [blank_start]12[blank_end]% or [blank_start]20[blank_end]% slope
    1. A0
    2. B12
    3. C20
  6. 6Sanz Electrode
    Measures PH
    Reference Electrode Contains: [blank_start]KCL[blank_end] solution with known PH, has contsant [blank_start]electrical[blank_end] potential.
    Measuring electrode contains: [blank_start]Buffer[blank_end] Solution, silver-silver chloride wire and pH sensitive glass capillary tube
    Introduction of sample causes electrical [blank_start]potential[blank_end] to develop. Voltage difference is proportional to PH [blank_start]difference[blank_end]
    1. AKCL
    2. Belectrical
    3. CBuffer
    4. Dpotential
    5. Edifference
  7. 7Sanz Electrode Calibration:
    Low pH solution: [blank_start]6.84[blank_end] - If displayed value is different than the known sample, adjust with the [blank_start]balance[blank_end] to known value.
    High pH solution: [blank_start]7.384[blank_end] - If displayed value is different than the known sample, adjust with the [blank_start]slope[blank_end] control to known value.

    1. A6.84
    2. B7.384
    3. Cbalance
    4. Dslope
  8. 8Tonomotry
    Used for quality [blank_start]control[blank_end] with ABG analyzers
    Allows precise gas mixtures to be [blank_start]equilibrated[blank_end] with buffer solution or whole blood samples
    Best method for precise control of [blank_start]Clark[blank_end] electrode
    Vert complex - not widely used
    1. Acontrol
    2. BClark
    3. Cequilibrated
