I hope the Report shows.
Thanks

Yes, it may be because the machine was off while I went to the bathroom, but it shouldn't be for 30 min, unless I forgot to put the mask back on right away. I'll check and make sure.
I attach a graph from last night. It shows 2.07 AHI’s , well above my usual avg of about .50.
2.07 AHI's is still quite O,K., but the graph also shows LL for 26% of the total sleep time, i.e. into the red zone. It is not the first time. Usually, I wouldn’t worry if I feel well, but lately I’m tired at wake up. It could be that there are more than marginal AHI’s that the machine does not record because of the LL and this could affect my sleep.
I’ll speak to my respirologist, if this persists. In the meantime, I’d appreciate if you can look at the graph, because I think I found some incongruities
More importantly, looking at the Flow Rate graph, it is at 0( or almost) for approximately 4 minutes and the Flow Limit graph goes flat for longer than 4 minutes, i.e. for most of the time zone of the LL. Does this point to some kind of breathing irregularity, or outright interruption, if only intermittent? If so, I wonder why there are no recorded AHI’s for most of the LL time zone.
Thanks as usual

by clicking on that triangle to suppress the month's calendar, there are no more details than previously.
The mask is an Air Fit F 20 L. I had it for about a year. I noticed that washing the silicone seal and my face every night improves the leaks, just as shaving. My beard is not very strong, but I found that even a short unshaven stub can let air through the seal.
The velcro straps, especially the lower one, are probably a bit worn and they would come off easily. I didn't think it was time to replace the silicon seal and/or the straps, though. I fastened them with tape after setting them comfortably and now they stay on, even though there is some air still leaking when I move the face or the jaw.
Here are the Pressure and Mask pressure graphs. What is the difference, anyway?
Thanks

I tried to remove the calendar again, but there are no more details than those already shown with the calendar on. I increased the Ramp start pressure to 12 as suggested, but I don’t quite understand because the pressure is already set at 12-16, so the machine should already work at 12. I enclose last night’s report. It shows quite a high % of LL, around 57%, the highest so far. On a closer look, I find a few oddities. The total sleep time is only about 4 hrs. In reality, it is longer than that, because I recall waking up with the mask still on at about 6 a.m. I then removed it and continued to sleep without it until around 9 a.m. The type of mask in the Resmed machine showed as pillows, instead as full face. I don’t know if this has any bearing, but I corrected it. The humidity level is set at 5, but last night I had an unusually dry mouth and this morning I found some water in the tank, which is usually empty. Thanks

I enclose today's report again, with maximum zoom on the Flow rate graph, showing 5 secs spans. I don't know how to interpret it in reference to the Large Leaks and possible hidden AHI's , if any. For one thing, I see no additional AHI events under the LL sections or anywhere in the event flag graph, even with max zoom. . Does this mean that there are no hidden AHI's ? Where would these hidden AHI's show at max Zoom level, if any?
Regarding the LL issue, I conducted a retroactive search since I began the therapy in June 2020. It appears that these LL started cropping in mid June 2021, intermittently at first and then picking up in number and duration. I never tried other masks, but I can only breathe through the mouth, due to a almost permanently blocked nose and polyps on the throat., so I cannot use either pillows or the other masks you suggested. My doctor knows that I cannot breathe through the nose, but the therapy has been so far successful, unless the large leaks issue has a negative bearing if it continues. I'll see how it goes with the liners. If worse comes to worse, I'll have to replace the silicon seal.
I received my Respironics Mask liners from Amazon. I put one on last night. A bit uncomfortable at first, because of the thickness of the fabric and also the size of mouth opening on the fabric, somewhat small, I thought. It touched my lips. But I could breathe OK and it didn't bother me during the night. The large leaks were however worse than ever. Practically uninterrupted from 3:30 to 6:30, some lasting 60 min, a few 30 and 40 min, for a total of 46% of sleep time. I don't know if it is because of the liners. I decreased the Ramp setting from 12 back to 10. See how it goes. I'm still not too sure how to read the Flow rate in connection with the LL. . I zoomed it max. THe AHI's are minimal, even by zooming. The Flow Rate waveform goes from +180 to - 120. I don't know what is the relevance of this amplitude.. I think these LL affect my sleep in a subtle way. I don't know if these machines go out of adjustment and need to be re-calibrated. I'll contact the sleep clinic to see if there are adjustments to be made or perhaps have the seal replaced.
Here is the graphic, if you can glean something that I don't see..
Thanks
