F&P SensAwake. Pressure kept artificially low?
I've managed to regularly get my AHI below two - mostly under one. However, looking at my flow rate graphs over since I got my machine, I notice more than a few SensAwake flags. I've expanded quite a few and can't see (don't recognize) waveforms that are indicative of the SensAwake flag. Yes, I know this flag is unique to the F&P Sleepstyle, so there may be relatively few here that can help explain it. I do see times where the SensAwake flag is missing, pressure generally keeps rising. So, is SensAwake keeping pressure artificially low?
Maybe if I understood waveforms better... what is normal... what is not normal...
I've attached two views of a 20 minute nap yesterday. I've zoomed in on a two-minute period about 13 minutes in where there are a couple different waveforms, and the waveform where the only SensAwake flag exists.
The first is the graph as-is. Note, APAP is set from 10-16cm, and SensAwake at 9.5cm. No ramp, no EPR. Also note actual pressure is steady at 9.5.
The second has four "question bubbles" focusing on specific points where different waveforms exist in the flow rate graph.
First is a series of "sawtooth" waveforms that appear to show full exhalation, but the breath in is ragged. In general, this is what the majority of waveforms look like for me. Explain?
Second is an anomaly, very ragged, long, inhale, very sharp deep exhale, then a two-step inhale afterwards. Explain?
Third shows some nicely rounded waveforms with some fuzz on top. This is also where the SensAwake flag exists. Explain?
Fourth is back to "my normal" sawtooth with ragged inhale, oddly shaped top transitions, and smooth rapid exhalation. Explain?
Thanks in advance for the time and expertise looking over this data.
