Sensor
The O
2
sensor calibration can be accessed in the Configurations menu, by
pushing the O
2
button.
The O
2
sensor is automatically calibrated when the device starts up and
every 24 hours when in use.
During calibration procedure, the FiO
2
concentration of the fresh gas to
patient is not altered.
• If a “Supply Gas Failure” occurs, the oxygen sensor calibration is
automatically disabled to avoid false sensor calibration.
• Press the 21% button to perform One-
point calibration at 21% O
2
.
• Press the 21 + 100% button to perform a
Two-point calibration at 21% and 100%
O
2
.
After one of these buttons has been the
Calibration procedure starts. If the procedure has
been successful, a Green check mark will appear.
The O
2
sensor can be turned OFF if that the O
2
sensor reaches end of life during use.
You are then expected to use a secondary
respiratory gas monitor until the ventilator can
safely be taken out of service to replace the O
2
sensor.
