RADIOMETER ABL800 FLEX - Units and Numerical Format of Derived Parameters

Units and numerical format of derived parameters
Calculated
versus estimated
parameters
Derived parameters are calculated or estimated on the basis of measured and keyed
in data. Calculations are made using equations programmed into the analyzer. The
accuracy of the calculations depends on the input parameters keyed into the
analyzer’s computer.
If the calculation of a parameter requires input from the operator, but this input is
not forthcoming, the analyzer will use certain default values (refer to the section
Default Values in this chapter).
Not all input parameters are stored as defaults. In these instances the dependent
derived parameter will not be reported if the relevant input parameter(s) is/are not
entered.
If the default values are used in the calculation of a parameter, then a parameter is
considered estimated (“e”) rather than calculated (“c”).
Acid-base
parameters
The table below lists the acid-base derived parameters.
(ABL83X FLEX corresponds to ABL82X FLEX, but it can measure ctBil and
FHbF).
