13 Monitoring Carbon Dioxide
214
When you see the message CO calibration done at <date and time> on the status line, the
zero calibration is finished and you can begin monitoring.
4 Install the airway adapter at the proximal end of the circuit between the elbow and the ventilator Y-
section.
WARNING
To prevent stress on the endotracheal tube, support the sensor and airway adapter.
Position sensor cables and tubing carefully to avoid entanglement or potential strangulation. Do not
apply excessive tension to any cable.
Replace the airway adapter, if excessive moisture or secretions are observed in the tubing or if the
CO

waveform changes unexpectedly without a change in patient status.
To avoid infection, use only sterilized, disinfected or disposable airway adapters.
Inspect the airway adapters prior to use. Do not use if airway adapter appears to have been damaged
or broken. Observe airway adapter color coding for patient population.
Preparing to Measure Sidestream CO2
1 Plug the sensor cable into the monitor's CO
2
input connector. Allow the sensor two minutes warm
up time
2 Connect the cannula, airway adapter, or sample line as appropriate, to the sensor. It will click into
place when seated correctly.
3 To zero the sensor:
