Sensor Calibration
Enter the Calibration Screen from the Setup Screen by pressing the calibration
button on the lower right hand corner of the touch screen. Ensure there is a minimum
8 LPM set on the NCPAP/PRES Low Flow meter. In addition, ensure there is a
minimum of 3 LPM set on the NCPAP/High Flow meter. Adjust the %O
2
control to
21%. Allow the %O
2
display to stabilize. Confirm the calibration by touching the
associated flashing button.
Adjust the %O
2
control to 100%. Allow the %O
2
display to stabilize. Confirm by
touching the associated flashing button. Return to the Startup Screen by pressing the
Exit button.
Note
If O
2
calibration fails, a red “X” is shown. Refer to the Service Manual.
If the internal oxygen cell is depleted or damaged, it may not be possible to calibrate
the O
2
sensor. The internal oxygen monitor may be disabled using the Disable O
2
button. This will disable oxygen monitoring and the audible oxygen alarms until the
device is powered off. Whenever the device is operating with oxygen monitor and
alarms disabled, a fault code E5 5 displays, and measured FiO
2
displays as dashes.
WARNING!
When the Infant Flow SiPAP unit is connected to a patient, and the internal
oxygen monitor is disabled, the Infant Flow SiPAP unit must be used with
an external oxygen monitor.
If calibration is attempted, and fails, or if the oxygen cell fails while the device is in
normal use, a Fault Code E5 5 displays, as tabulated in appendix D, and a high
priority alarm is indicated visually and audibly. To enable continued operation, the
internal oxygen monitoring may be disabled by pressing and holding the alarm mute /
reset button for 3 seconds. This disables the internal oxygen monitor and alarms and
clears the alarm condition. The E5 5 code remains to indicate that the oxygen
monitor is inoperative. An external oxygen monitor must be used.
