7. Connect the sampling line to the patient as described in the directions for use
supplied with the sampling line.
8. Perform the following checks:
a. Check that CO2 values appear on the monitor.
b. Check the patient type. Make sure it is correct to ensure accurate sampling.
c. Touch the alarm control to ensure the alarms are set appropriately.
d. Toggle to the waveform view to ensure that a complete waveform appears.
Note
When the cannula is not on the patient, the etCO2 value is blank.
Note
After you connect the sampling line, the monitor immediately searches for
breaths, but it does not indicate a No Breath condition before any valid
breaths have been detected.
Note To avoid moisture buildup and sampling line occlusion during suction or
nebulization of intubated patients, stop the CO2 pump and remove the
sampling line luer connector from the monitor.
Note
Replace the sampling line according to hospital protocol or when a
blockage is indicated by the device. Excessive patient secretions or a
buildup of liquids in the airway tubing might occlude the sampling line,
requiring more frequent replacement.
Note When the message "Check for occlusion in gas line" appears on the screen,
indicating that the sampling line attached to the monitor is blocked, the
monitor’s CO2 pump will stop. Follow the instructions in the
Troubleshooting section of this manual to correct the problem.
Stop and restart the CO2 pump
Stopping the CO2 pump prevents the ingress of fluids into the CO2 module during
certain patient procedures (such as suction or lavage). In addition, this pump-stop
condition pauses the monitoring of all parameters obtained from the CO2 module for a
configured period of time or until you restart the CO2 pump.
1. To temporarily pause or stop CO2 monitoring, touch the pump-stop button
in the etCO2 frame.
Note This button is a toggle. When you stop the CO2 pump, the
Start button with a countdown timer appears.
2. To resume CO2 monitoring, touch the pump-start button .
The CO2 pump restarts, the current timer clears, and the Stop button appears in the
frame.
