Resp Display Amplitude
The Size option lets you increase or decrease the amplitude of the
respiration waveform. In manual breath detection sensitivity
mode (see the section Selecting the Rsp Mode, below), the detec-
tion sensitivity is based on the selected waveform amplitude.
Available amplitude settings are:
! 10% to 100%, in increments of 10% (default 50%)
WARNIN G: In Manual Mode, if you set the size of the
respiration waveform too low, shallow breaths may not
be counted. If set too high, cardiac artifact might be
counted as breaths. Therefore, always turn respiration
markers on in manual mode to help you select an appro-
priate waveform amplitude/detection sensitivity (see the
section Displaying Rsp Markers).
STEPS: Selecting the Rsp Display Amplitude
1. Click on the Rsp waveform channel.
2. Click on
Size.
3. Select the desired display amplitude and click the knob.
