4.3.2.3 Oxygen cell calibration
NOTE:
• Disconnecting the patient from the ventilator is not
required when performing the oxygen cell calibra-
tion.
• The oxygen cell calibration requires that an oxygen
cell be installed, that the device`s oxygen monitoring
is enabled, and that oxygen be available.
• Oxygen alarms are suppressed during oxygen cell
calibration.
Description: During this 2 minute calibration of the oxygen
cell, the device delivers the operator-set oxygen percentage to
the patient. It tests the cell and resets the calibration points
specific to the cell in use.
Procedure:
1. Ensure the appropriate gas supplies are connected to the
device.
2. From the
Tests & calib
window, touch the
O
2
cell
button.
3. Verify that, after 2 min,
O
2
cell calibration OK is displayed.
Close the
Tests & calib
window.
Possible corrective action: If
O
2
cell cal. needed
is dis-
played, the cell could not be calibrated. Verify that the oxygen
cell is correctly installed and the cable connected and that oxy-
gen is available. Repeat the calibration. If the calibration fails
a second time, you must install a new oxygen cell. If
O
2
cell
defective
is displayed, you must install a new cell.
