17 Monitoring SvO2

Performing In-Vivo Calibration

Performing In-Vivo Calibration

Perform an in-vivo calibration:

•if you place the catheter in a patient without performing a pre-insertion calibration.

•if the catheter was disconnected from the optical module.

•when the catheter has been in the patient for 24 hours.

•if any significant change in light intensity occurs that the monitor cannot correct automatically.

Setting Up the In-Vivo Calibration

Check for:

•proper positioning of the catheter in the patient.

•relatively stable oxygen saturation in patient.

•that the SvO2 light intensity indicator covers at least two divisions above the midpoint.

Making the In-Vivo Calibration

1Be prepared to draw a blood sample from the patient.

2In the Setup SvO2 menu, select Start In-VivoCal.

3To clear the distal lumen, draw off and discard at least 2 ml of blood before taking the sample.

4Draw a blood sample from the distal port of the catheter and flush the line according to standard hospital practice.

5Obtain laboratory analysis of the sample using direct measurements.

6Compare the results with the stored calibration value displayed in the Setup SvO2 menu. If the difference is less, or equal, to 4%, you can skip the next step.

7If there is a difference of more than 4% between the stored value and the laboratory value, select CalibrationValue to adjust the stored value. Selecting Recall PreviousC recalls the previously stored calibration value.

8Complete the calibration by selecting Store In-VivoCal(even if you did not adjust the calibration value). This updates the data stored in the optical module.

Calculating Oxygen Extraction

Oxygen extraction is the difference between the measured SpO2 and SvO2 values. If you are

monitoring SpO2 and SvO2, the monitor can calculate this value and display it as a numeric.

♦To switch oxygen extraction calculation on or off, in the Setup Sp-vO2menu, select Sp-vO2and toggle between On and Off.

♦If more than one SpO2 value is available, you must choose which value is used in the calculation. In the Setup Sp-vO2menu, select SpO2 Source and select the required source.

If one of the calculation sources becomes unavailable, the monitor displays the INOP

Sp-vO2 CHK SOURCES for one minute. After this time, the calculation automatically switches off. If the missing source becomes available again, the calculation automatically switches on again.
