Sensor Calibration
1. Enter the Calibration Screen from the Setup Screen by pressing the calibration
button on the lower right hand corner of the touch screen.
2. Ensure there is a minimum 8 LPM set on the NCPAP/PRES Low Flowmeter. In
addition, ensure there is a minimum of 3 LPM set on the NCPAP/High
Flowmeter.
3. Adjust the %O
2
control to 21%. Allow the %O
2
display to stabilize. Confirm the
calibration by touching the associated flashing button.
4. Adjust the %O
2
control to 100%. Allow the %O
2
display to stabilize. Confirm by
touching the associated flashing button.
5. Return to the Start up Screen by pressing the Exit button.
Note:
If O
2
calibration fails, a red “X” is shown.
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 E55 displays, and measured FiO
2
displays as dashes.
WARNING!
When the Infant Flow
®
LP SiPAP system unit or SiPAP system unit (part
number 675-CFG-xxx) is connected to a patient and the internal oxygen
monitor is disabled, the Infant Flow
®
LP SiPAP system unit or SiPAP
system 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 E55 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 three seconds. This disables the internal oxygen monitor and alarms
and clears the alarm condition. The E55 code remains to indicate that the oxygen
monitor is inoperative. An external oxygen monitor must be used.
