4. ETT Movement Smoothing
In the event that there is artifact in the echo waveform from the patient airway, the ETT movement indicator may
display “jumpy” results. In extreme cases, this may result in nuisance alarms for high or low tube tip movement.
The AirWave provides a feature to smooth out these jumpy readings.
To enable this smoothing filter, navigate to the
Main Menu
,
and select “
ETT Movement Smoothing
”.

Home and Waveform screens will now display “SM On” to indicate the feature is enabled (see Figure I-3). On the
Home screen, the indicator is located near the upper left corner of the screen; on the Waveform screen, the
indicator is located above the airway waveform.
