Reading for the comparison itself: Why Does My AHI Change Night to Night? Normal Variation Explained — what is noise and what is a trend. Why Is My AHI High on CPAP? Causes and How to Find Yours — when the number really has moved, and the usual reasons. CPAP 95th-Percentile vs Median Pressure: What the Numbers Mean — the pressure figure that is worth comparing across months. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Last thing, and the one that matters most in week one: the point of all this is not the numbers. It is whether you feel better in a month than you do now. If you are struggling — genuinely cannot tolerate it, or you are lying awake fighting the machine every night — that is a thing to raise early rather than endure quietly. Masks get changed, pressures get reviewed, humidification gets adjusted, and all of that is normal early-therapy housekeeping done by the people looking after you. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Reading: CPAP Mask Types and Fit: Nasal, Pillow, and Full-Face Compared — the three classes, what each does well, and how to size them. CPAP Nasal Congestion and Stuffy Nose: Causes and Fixes — question 1 above, which decides more of this than anything else. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Reading, for the three separate problems this thread braids together: CPAP Dry Mouth and Mouth Breathing: How to Stop It Tonight — the dryness itself. CPAP Mask Leaks & Mouth Leak: Causes, the Data Threshold, and Fixes — the leak checklist, in order. CPAP Nasal Congestion and Stuffy Nose: Causes and Fixes — for when the nose is part of the story.

Since this is the bug category, the shape of a report we can actually act on: What you did, in the order you did it. What you expected, and what happened instead. Where: which view, which browser or the phone app, roughly when. Screenshots with the numbers cropped out if you would rather not share them — the layout is usually what we need, not your data. What not to put in a public thread: your account e-mail, your device serial number, or a photograph of anything from a clinic. If a report needs your account looked at, the in-app feedback button is attached to it and this board is not.

One thing worth saying to anybody weighing this up who is new to CPAP data: you do not need the deep-analysis engines to answer your first three months of questions. Usage, AHI, leak and pressure — the numbers that a clinic actually reviews — are all on the cheaper tier. The engines earn their keep for the specific case of "my numbers look fine and I still feel terrible", which is a real and common case, but it is not where anybody starts.

The shelf on both halves of this: CPAP Mask Leaks & Mouth Leak: Causes, the Data Threshold, and Fixes — the checklist above with the sourced detail. Mask Off & Large-Leak Events: Why Your CPAP Report Shows Gaps — what the large-leak and mask-off markers actually mean in your data. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The follow-up question this always produces, so let us pre-empt it: after the import succeeds, that machine shows up as a BMC device rather than under the name on the box. That is correct and it is your machine. The Luna G3X is manufactured by BMC Medical and sold under a different brand; internally the device identifies itself with the manufacturer's model name, and the app reports what the machine says about itself rather than what the retail box says. Your data, charts and settings are complete — only the label differs. Worth knowing for the same family of machines: their cards use a newer format that some older desktop tools, including released OSCAR versions, cannot read at all. If you have been told your machine's data is unreadable, that may be why.

A framing that helps, since this is really a question about what a number over 90 days is for. A quarter-long average is not a better version of last night. It answers a different question — "is the direction of travel right?" — and it answers it best when you look at it rarely. Reading a 90-day average every morning is a way to feel bad about noise: the number moves for reasons that have nothing to do with your therapy, and the wide scope exists precisely so a single bad night stops mattering. If a trend genuinely is moving the wrong way over weeks, that is exactly the thing to take to the person who can act on it, with the printable report from the Reports page in your hand.

The shelf covers each of these properly: CPAP Flow Limitation: The Hidden Metric Beyond AHI — the metric that explains most of this thread. RERA and Flow Limitation: The Events That Don't Show in Your AHI — arousals that never become scored events. UARS (Upper Airway Resistance Syndrome): The Diagnosis Your AHI Misses — the diagnosis that a good AHI can hide. Still Tired on CPAP With Good Numbers? Reasons and Next Steps — the overview, if you want one page rather than four. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

For the background rather than the buttons, the shelf has the articles this thread keeps circling: CPAP Flow Limitation: The Hidden Metric Beyond AHI — why a near-perfect event count can sit on top of hundreds of flow-limited breaths. UARS (Upper Airway Resistance Syndrome): The Diagnosis Your AHI Misses — the condition that lives in exactly that gap, and why a home sleep test can come back normal. Still Tired on CPAP With Good Numbers? Reasons and Next Steps — the checklist people actually arrive with. The engines can show you a pattern. What that pattern means for you is a conversation with the person who can order a test and change a prescription. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

One more sighting of the same family, worth knowing before you report it: a view that still shows data you just deleted or cancelled. Deletions and cancellations finish in the background, and the app refreshes itself when the cleanup completes. If a chart or calendar looks stale in the meantime, press F5 — browsers cache these pages hard. If it is still there after a refresh and a minute of patience, that is a real bug and worth a report in Bug Reports. And the standing rule for everything on this board: numbers on a screen are a description of one night, not a verdict on your therapy. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The shelf on this: CPAP Dry Mouth and Mouth Breathing: How to Stop It Tonight — dry mouth and mouth breathing, with the full set of fixes. CPAP Mask Types and Fit: Nasal, Pillow, and Full-Face Compared — what each mask class does well and badly. CPAP Nasal Congestion and Stuffy Nose: Causes and Fixes — for step 1 above, which is the step most people skip. Nothing on SomniTalk is medical advice.

A related one, because it produces the same "is it stuck?" feeling: an import that shows "Queued (position N)". Two imports run at a time across the whole service. If both slots are busy — which happens when somebody uploads to several profiles back to back — yours waits, and starts by itself when a slot frees. Nothing is lost by queueing and nothing needs re-uploading. The processing indicator stays visible the whole time; that is how you know it is alive. The genuinely stuck case looks different: the indicator disappears and no sessions arrive. The server's watchdog marks a dead import as failed and tells you to re-upload — and because of de-duplication, re-uploading is safe.

Worth saying out loud for anybody new reading this: you cannot break your data by uploading too often. People new to this tend to upload once, get a scare, and then not touch it for a month. Upload the whole card whenever you happen to have it out — after a trip, at the end of a month, whenever. Only the new nights land. There is no counter, no penalty, and no way to create a duplicate night by trying.

The shelf for this, in the order it is most useful: Still Tired on CPAP With Good Numbers? Reasons and Next Steps — the same question with the sourced version of the answer. CPAP Leak Rate: What's Acceptable and How to Fix High Leaks — the number to read next to the event count, and why. Why Does My AHI Change Night to Night? Normal Variation Explained — why the figure moves when nothing has changed. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The reference versions, for anyone who would rather read than ask: How to Read Your CPAP Data: A Plain-English Guide to AHI, Leak Rate & Pressure — the whole page, in the order above. CPAP Leak Rate: What's Acceptable and How to Fix High Leaks — step 1, and the one that decides whether the rest is worth reading. One thing this board will not do: nobody here will tell you what to set your machine to. What a chart read gets you is a clear description of what is happening and when — which is what makes an appointment productive. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

One hardware footnote, because it costs people an evening. You need a card reader that actually reads the card, and on most machines the card is a full-size SD card sitting behind a flap. Take it out with the machine switched off, and put it back the same way. Removing the card does not erase anything and does not harm the machine — the machine writes to it again the next night. Do not rename, tidy, move or "clean up" anything on the card before uploading. The folder names are the importer's map. If you have already tidied a card, no harm done — put the files back where they were, or upload the card again after the next night's recording. For the brand-by-brand background, the shelf has an overview topic: CPAP Machines & Devices, and a walkthrough of getting the data off the card: How to Download CPAP Data from Your SD Card (ResMed, Philips, Löwenstein, BMC, Hoffrichter).
