Are you using PS 8 due to respiratory issues other than OSA? If so, I understand, but if not, isn't 8 too high? ASV machines are used for those with mixed apneas of OA and Centrals. I have been studying the use of a bilevel machine for simple OSA. Most suggestions for PS to address FLs are not over ...

My attempt at taping with a full face mask failed because I needed to mouth breathe during sleep. A collar and chin strap also failed. I have come to accept that mouthbreathing is how I must breathe when in the supine position. I only mouth breathe in the supine position. I cannot avoid rolling from...

Good to hear I have some company in my misery! I am seriously contemplating maxillary expansion for my nasal issues but that’s down the line. Do you sleep in any kind of incline? I’m thinking if I can get in a good incline, on my back, with cervical collar to keep it all in place, I might be able t...

I am in deep study of the Bilevel machine. After examining my breath shapes, it looks like I could benefit from an AirCurve Vauto in Vauto mode to make breathing more natural and ease the work of inhaling with 14cm at the mask. You tried Bilevel and came back to APAP? Maybe the correct settings of t...

You wrote: "Basically I feel like I can breathe through my nose pretty well during the day." I nose breathe all day long. I nose breathe when I side sleep. It is ONLY when on my back, my mouth opens, the mouthbreathing begins, as well as severe sleep apnea. I am not saying you are mouth breathing de...

Your latest Sleep HQ report shows OSA well treated at 14cm. I see no variance in the average pressure, so I guess you are in fixed mode. I think I have written how using Auto mode with a range can help find the lowest possible effective IPAP pressure. Uncle Nicko of Sleep HQ made a video on using th...

Please be aware that mouth breathing during sleep can be an involuntary action to breathe, not just a mouth leak when using a nasal/pillows mask. I made the mistake of trying to force myself not to mouth breathe by collar/tape/chin strap.My jaw found a way to breach all three so air could pass throu...

I have Oscar I just forgot to put in my SD card last night. I guess maybe I’ll try to adjust those other settings to help with breathing. But it feels like it’s a dryness issue so I’m not sure how they’ll address it. Use your humidifier settings to address dryness issues. The humidity level needed ...

What would be helpful is to post an OSCAR chart. It will show which machine you are using and its settings. OSCAR is available at Sleepfiles.com. The Apple Watch data may not be accurate. It could mistake movement during sleep for being awake. With AirCurve Vauto bilevel, the Trigger/Cycle/Tmax/min ...

Med (median) pressure is up, indicating Min will be more effective at a higher setting. Raising Min until it is close to Med is fine tuning your therapy pressure for fewer fluctuations. You can see from the red line that Min 9 is not your optimum therapy pressure. Trying Min 10 will help find it. AH...

I have taped, collared, chin-strapped, and used anti-back sleeping gadgets. ALL failed. I was recently told by a chin strap dealer that chin straps are for relaxed chins, not a device to prevent mouth breathing. I must mouth breathe at times; therefore, I must use a full face mask. What some call mo...

I remember now. My message folder was cleared recently, so I don't have the message you requested from me. I cannot recall it either due to forgetfulness. Banning from Apneaboard can be temporary as a warning, but maybe you were permanently banned. Please read the rules section if you can re-enter. ...

Does anyone know why some have such a breath wave shape? Yes. Using APAP not BiLevel so what do you think causes the steep to a point waves? Did you do that favor about Albercook that I asked you to do for me? I do not have an Albercook favor asked of me. I am curious as to why breath waves show as...

Yes.

The first thing to fix is the leaks. Your very high Leak Rate and Large Leaks prevent effective therapy and data reporting. Run the mask fit test. Let it build to max pressure. Twitch your nose and mouth, move your head a bit. Lie in the positions you will be sleeping. Get the mask and headgear in o...
