14 Monitoring Carbon Dioxide
When you see the message
zero calibration is finished and you can begin monitoring.
Install the airway adapter at the proximal end of the circuit between the elbow and the ventilator Y-
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
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
