Specific Parameter Guidelines - Siemens Rapidlab 1200 Operator's Manual

8-14
• If you turn a parameter off, leave Setup, and then turn the parameter on again in Setup,
you may need to calibrate and QC the parameter.
The sensor for that parameter is out of calibration until it passes a successful
calibration. The sensor may also have failed QC if Required QC or AutomaticQC was
scheduled while the parameter was turned off.
• When you select a parameter that uses a sample demographic to report results, the
system automatically turns the demographic on.
For a list of parameters that are dependent on sample demographics and other
parameters for results, refer to Required Parameters and Sample Demographics‚
page 8-17.

Specific Parameter Guidelines

Using Hct
• On Rapidlab 1245 and 1265 systems, Hct is a calculated value determined from the
tHb result.
• To report Hct, ensure that tHb is selected at the first Parameters On/Off screen and Hct
is selected at the second screen.
Using O
• You can select both O
If parameters that are required to report sO

Using tHb
• When tHb is on, the CO-ox fractions are also on.
• If tHb is off, the CO-ox fractions are off.
NOTE:
the fractions are turned on.
• When tHb is selected at the Sample Demographic screen, tHb is not available on the
Parameters On/Off screen.
