CO2 with CAPNOSTAT Mainstream, CapnoFlex LF, and Dual CO2 modules
9. Check the monitor screen. If the message Calibrate sensor appears, calibrate the
sensor. If the message Check/calibr. adapter appears, calibrate the adapter.
10. Block the open end of the sample line or nasal cannula. Within 90 seconds the
pump will shut off and the message Sample line blocked should appear on the
monitor display to ensure that the monitor recognizes blockages.
11. To turn the pump back on and return to normal operation, turn the pump off and
then back on again in the CO
2
setup menu. The pump will turn back on and the
module will return to normal operation.
12. Connect the sample line to the patient. Ensure that the tubing is not hanging
lower than the patient.
NOTE
Delivery of bronchodilators and/or mucolytics via aerosol and
meter dose inhalers can be corrosive and cause premature
blockage of the water trap. Discontinue sidestream gas
analysis prior to treatment by switching the pump off and
removing the sample line from the breathing circuit.
Calibrating the Dual CO2 sensor
Sensor calibration should be performed whenever the message Calibrate sensor
appears.
1. Place the sensor away from all sources of CO
2
, including the patient’s exhaled
breath, your exhaled breath, and ventilator exhaust valves.
2. With the cable connected to the module, select a gas related parameter window >
Calibration .
3. Place the sensor on the cell marked 0 and select Start Calibrating .
4. After the message Zeroed appears, remove the sensor from the 0 cell and attach
it to the cell marked REF .
The measured EtCO
2
value appears in the Connect sensor to REF cell window. If
the value stays between 36 and 40 mmHg for three seconds during the 20-second
calibration, the calibration is successful and the message
Calibrated appears. If the
calibration fails, the message Recalibrate appears instead. In this case, perform
a new calibration.
Calibrating the Dual CO2 adapter
Adapter calibration should be performed whenever the message Check/calibr.
adapter appears.
1. Place the sensor and adapter away from all sources of CO
2
, including the patient’s
exhaled breath, your exhaled breath, and ventilator exhaust valves.
2. With the adapter connected to the sensor and the sensor connected to the
monitor (and, when used, all sidestream tubing attached and the pump turned
on), select a gas related parameter window.
3. Select the Calibration tab.
4. Select Start Calibrating .
The message Calibrated appears on the screen after a successful calibration. If the
calibration fails, the message Calibration error appears instead. In this case, perform
a new calibration.
