Breath Detect
The Analyzer uses a built-in breath detection algorithm. The algorithm determines the
breath phases, rejecting signal noise and other artifacts.
Breath Detect Threshold
The Analyzer breath detection algorithm uses a flow rate threshold that the flow must
cross to trigger a change in the breath phase. Higher flow rate thresholds yield less
sensitive breath detection. Lower thresholds yield more sensitive breath detection.
To enter a new threshold, select Threshold from the Breath Detect menu under the Setup
menu, as shown in Figure A-32.

The dialog box shown in Figure A-33 now appears, allowing you to enter your new
value. Change the value by using the scrolling arrows or by entering a number directly.
