1.6.13.3 Pump Calibration
Pump calibration is necessary when the tubing configuration or sampling cell airway adapter
is changed. This calibration enables the unit to determine when an occlusion is present in the
tubing.
To perform a pump calibration:
1.
Plug the Capnostat® CO
2
sensor into the Passport XG CO
2
connector (34). The “CO
2
:
Sensor Warming Up” message is displayed. The pump calibration cannot be performed
until the “CO
2
: Sensor Warming Up” message disappears.
2.
Press the CO
2
PUMP key (12). A “Warning” message displays. Ensure that the sampling
tubing is correctly connected and that the nasal cannula is clear of all sources of CO
2
(including the patient’s and your own exhaled breath, and ventilator exhaust valves).
Press SELECT to turn the sampling pump on and to initiate the calibration.
3. The “CO
2
: Pump Cal in Progress” and “CO
2
: Pump On” messages alternately display.
When the pump calibration is complete, the message “CO
2
: Pump Cal Complete”
displays and then the “CO
2
: Pump On” message displays. The “CO
2
: Pump On”
message will continue to display as long as the pump is on. See “Sidestream CO
2
Messages (on Passports with Sidestream CO
2
only)” on page 1-164 for additional CO
2
messages.
NOTE: This pump calibration also calibrates the adapter. It is not
necessary to perform a separate adapter calibration at this
time, unless the message “Check Adapter” displays.
NOTE: If the monitor detects changing CO
2
levels (breaths) during a
pump calibration, a “Breaths Detected ... Retry” message
displays and then a “Pump Cal Failure” message will
display. Remove the source of CO
2
and repeat the
calibration.
1.6.13.4 Adapter Calibration
Performing a Pump Calibration automatically calibrates the adapter. An Adapter Calibration
is necessary whenever the sampling cell airway adapter is replaced or when the “Check
Adapter” message displays.
To perform an adapter calibration:
1. Plug the Capnostat® CO
2
sensor into the Passport XG CO
2
connector (34). The “CO
2
:
Sensor Warming Up” message is displayed. The adapter calibration cannot be
performed until the “CO
2
: Sensor Warming Up” message disappears.
2. Ensure that the nasal cannula is away from all sources of CO
2
(including the patient’s
and your own exhaled breath, and ventilator exhaust valves).
3.
Choose Start Adapter Cal - Yes from the CO
2
menu. (See “Use of Menus” on page 1-
109.)
NOTE: If the monitor detects changing CO
2
levels (breaths) during
an adapter calibration, a “Breaths Detected ... Retry”
message displays, and then an “Adapter Cal Failure”
message will display. Remove the source of CO
2
and repeat
the calibration.
