RE: What is an "acceptable" Large Leak percent?
@Boxcar, you wrote:
Even though the hypopnea definition is >30% reduction in VOLUME, the actual values that are compared (to test for the >30%) are the peaks of the flow rate data on inhalation. If you can show me where that is incorrect, I'd appreciate following up.
Additionally, I think that I've found that there is a significant time-lag in calculating & reporting the tidal volume, so I've not focused of trying to associate tidal volume with instantaneous single deep breaths.
Quote:I even got a hypopnea flag last night during a sequence of what looked like otherwise pretty normal breathing because of the change to reported tidal volume and minute vent over the course of about 30 seconds.
