Patient samples
The following table describes the analytical process of a blood sample
measurement with the ABL90 FLEX analyzer system.
Stage Description
1. The analyzer is ready to accept a patient sample.
"Ready" message is displayed
Traffic light is displaying a GREEN or YELLOW light
The desired parameters are available
2. At the Ready screen, the user lifts the inlet handle to the syringe or
capillary position. The sample (syringe or capillary tube) is pressed
against the inlet gasket and the inlet probe extends into the sample,
which is automatically aspirated. A 1-point calibration is performed
by sampling on the CAL1 (rinse) solution.
3. The sample is drawn into the sensor measuring chamber and the
oximetry module. This process is controlled by liquid sensors that
also check sample homogeneity with respect to air bubbles. A "?"
appears in case of an inhomogeneous sample.
In case of problems during the process or in case of insufficient
sample, the measuring process is aborted, as the validity of the
measuring result may be compromised.
4. When the aspiration is finished, close the inlet.
5. Measurement of the sample is performed as soon as the sample is
positioned in the measuring chambers. The measurement takes 35
seconds. Concurrent with sample analysis, the user enters patient
information as necessary.
6. When the measurement is complete, the results are computed and
then displayed on the screen and a rinse process starts. For further
information on the rinse process see page 3-6.
