O2 Sensor Calibration
O2 sensor calibration is performed to ensure accuracy of the sensor. Inaccuracy of the sensor
will result in erroneous measurement and incorrect recognition. Calibrate O2 sensor before
using the ventilator and after replacing the oxygen sensor. Before this test, make sure that air
and oxygen sources are available and the patient breathing circuit is disconnected.
Press START button and wait until the calibration process is complete. New and previous
sensor calibration results are displayed. Select SAVE to store new calibration results.
As
shown in the figure, the type of oxygen sensor (Galvannic/ Permanent) is displayed at the top
of this screen.
Warning
Note that the oxygen sensor calibration must be performed with 100% oxygen
source.
