Two things worth separating, because they get argued as one. Whether the data is being collected is a question about your machine and its modem. Who can read it, and for how long is a question about the portal your supplier and clinic use, and about the account relationships behind it — which can outlive your relationship with that supplier unless somebody removes them. Neither question has a single answer across countries or manufacturers, and neither is answered by the leaflet in the box. The one thing under your own control in every case is keeping the detailed record yourself: How to Download CPAP Data from Your SD Card (ResMed, Philips, Löwenstein, BMC, Hoffrichter) covers getting it off the card.

The half that belongs in a clinic conversation rather than in a forum: aerophagia is one of the classic reasons a pressure prescription gets revisited. Comfort features that ease the pressure on exhalation exist partly for this, and so do other modes — but which of those applies is a judgement made from your data and your history by the person who prescribed it. What you can bring is precision. Note which nights were bad, what the pressure was doing on those nights compared with good ones, whether the bad nights were also the high-leak nights, and whether it correlates with position or with the evening. "It is worse on the nights the machine spends longest at the top of its range" is a genuinely useful sentence. What not to do is lower your own pressure to stop the bloating and leave your apnea untreated in exchange. That trade is a real one and it should be made by somebody who can see both sides of it. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

When it is worth picking up the phone rather than watching the trend, in plain terms: the clear-airway count is not settling after a couple of months, or is climbing; the pattern is regular waxing-and-waning breathing rather than isolated pauses; you feel worse rather than better, or you are waking gasping; you have a heart condition, or take opioids or other respiratory-depressant medication — both of these change the picture and both are reasons to have it looked at rather than watched. What not to do in the meantime: do not raise your own pressure to try to clear them. Pressure is a common cause of this pattern, not a cure for it, and the direction of travel is a clinical judgement made from your data. Neighbouring article: Central vs Obstructive Apnea: What 'Clear Airway' (CA) Events Mean — for telling the two apart before drawing conclusions. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The practical half: how to make a settings conversation actually go somewhere. Bring weeks, not nights. One bad night is a story; four weeks of the same pattern is evidence. Bring the pattern in one sentence. "Pressure sits at the top of its range for the last two hours and my events cluster there" is something to work with. "I think my pressure is too low" is an opinion, and it will be met with one. Say what you feel, not only what you measured. Bloating, waking gasping, a mask you fight — those are clinical information too, and they are frequently the thing that changes a decision. Ask what would need to be true for a change to be considered. It converts a no into a plan. One change at a time, then wait. Whoever makes the change, changing several things at once and judging it after two nights teaches you nothing. This is the oldest rule in this hobby and it is the most ignored. And if you genuinely cannot get anyone to look at your data — which happens, and is a real problem rather than a personal failing — that itself is worth saying out loud to your GP or family doctor, who can refer. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

One data note, because it decides more of this choice than the spec sheet does. Machines differ in what they record and how you get it out. Some write a full night of detailed data to a card that you own; some report a reduced summary to an app and nothing else; some do both but only if the card is actually in the slot. If you ever want to answer a question more specific than "was my AHI under 5", that difference matters more than the model number. So the practical question to ask before buying anything: does this machine take a card, and does it write detailed data to it? If the answer is no, every future conversation about your own therapy is limited to what a summary screen chooses to show you. Nothing on SomniTalk is medical advice.

This category is about the forum, not about the SomniCharts app. App bugs belong in Bug Reports; app ideas belong in Feature Requests. Fair game here: Something on the board is broken — a page that will not load, a button that does nothing, an email that never arrives, a layout that falls apart on your phone. The category structure does not fit how you actually think about the subject. Genuinely useful feedback, and easier to change now than later. A moderation decision you think was wrong. Say so once, calmly, and name the thread. Something is unreadable — contrast, font size, dark mode, or a table that will not scroll on a small screen. A rule that is unclear or that produces a silly outcome. Helpful details: what device and browser, what you clicked, what happened, and a screenshot with your own details cropped out. This board is in beta. Some of what you find will be half-finished, and telling us which half is the most useful thing you can do this week. Nothing on SomniTalk is medical advice.

Why can't I post yet? Posting requires a verified email address. Register, open the mail we send, click the link, and the posting categories open up. Until then you can read everything. The verification mail never arrived. Check spam and any "promotions" tab first. Then use the resend control on your account page. If it still does not arrive, some mail providers silently discard forum mail — post in Site Feedback from the account, or contact us through the SomniCharts site. Is my SomniTalk account the same as my SomniCharts account? No. They are separate systems with separate logins on purpose. Nothing you post here touches your therapy data, and nothing in your SomniCharts account is visible here. Using the same email address for both is fine; using the same password is not a good idea anywhere. Can I change my username? Ask in Site Feedback. Renames are done by hand because they rewrite every mention of you on the board. Can I edit or delete my own posts? Yes — edit and delete are available on your own posts once your account is verified. Edited posts show that they were edited; that is deliberate, so that a thread still makes sense after the fact. A post that other people have already replied to should be edited rather than gutted — leave the question standing so the answers still mean something. How do I delete my account? Ask in Site Feedback or by the contact route on the SomniCharts site. We remove the account and disassociate your posts. Note that we will not silently delete a long thread that other members contributed to — tell us if you want the content removed as well as the account, and we will talk it through. Do you sell or share what I post? No. The board stores your username, email address, posts and connection metadata, and that is it. See /privacy for the specifics, including how to ask for a copy or a deletion. Is the forum searchable from outside? Yes. Topics are public and indexed by search engines. Post accordingly. Something on the forum itself is broken. Site Feedback, please — not the SomniCharts bug category, which is for the app. Nothing on SomniTalk is medical advice.

Current prices are on the SomniCharts pricing page — this topic is about what you actually get, which is the part the price list does not explain well. Free / lapsed Your account and your data stay. You can sign in, upload, and see the basic dashboard tiles. The analysis engines are locked. Nothing is deleted for being on the free state — re-subscribing unlocks the rest of what is already there. Silver — the core experience Uploads, the dashboard tiles, Daily, Overview, Statistics and Reports. This is a complete way to follow your therapy over time. What is not included: Charts View waveforms, SomniScan deep analysis, SomniPattern pattern detection, and SomniDoc. Those tiles show a lock and say what they need. Gold — everything SomniDoc AI analysis, Charts View waveforms, SomniScan, SomniPattern, the full deep analysis experience, and the Clinician Brief with its printing, PDF, tracked email and 14-day share links. The honest bit If you want to watch your therapy — usage, leak, AHI, trends — Silver is genuinely enough, and plenty of people stay there. If you want to investigate your therapy — waveform detail, pattern hunting, and an assistant that explains what it sees and can hand a summary to your doctor — that is Gold, and Silver will frustrate you. Trials and changes New accounts get a seven-day trial of the paid experience, and picking or changing a tier starts a fresh seven-day window before billing. Trial time is tracked per person, so deleting and recreating an account does not mint new trial days. Changing tier revises the same PayPal subscription; downgrading re-locks the Gold features at the change. Extra profiles beyond the two free ones are a separate add-on — the app shows the amount and asks before revising your billing, and deleting one reduces it again. Billing problems are not a forum topic. If a charge looks wrong or your tier does not match what you are paying, use the in-app feedback button with your account email — those get checked against PayPal directly, which nobody in a public thread can do.

The official Android app (SomniCharts, com.somnicharts.mobile) is on Google Play. It signs into the same account and shows the same profiles and the same data as the web app. iOS is planned but not yet available. What it does The dashboard adapted to a phone screen, including SomniDoc analysis. Uploads from the phone. Put the card in a reader (or OTG adapter), tap upload, and pick the card folder with Android's system folder picker. It streams to exactly the same import pipeline as the web: recognised cards import, unrecognised folders go to DropBox review, same as the browser. Background imports and queueing behave identically — the work happens on the server. SomniDoc follow-up questions, and a History chip listing that profile's past analyses (tap to re-read, swipe to delete). Account deletion and profile management. What is not on the phone yet The Memory panel — what SomniDoc remembers, adding a fact by hand, and Forget everything. Those live on the website. The Clinician Brief and its sharing tools. The phone's Share button still exports the answer you are looking at as a PDF. The History chip is hidden entirely when memory is switched off for that profile; the switch itself is on the website. Two things that catch people out Subscription checkout opens in your browser via a one-time link. That is deliberate: mobile browsers isolate cookies, so the app hands you off safely rather than pretending to be signed in. Complete PayPal there and the app picks the tier up. Luna G3X / BMC G3 cards need app version 1.12 or newer. Older versions do not recognise that card layout and send it to DropBox review instead. Update and re-upload, or use the web app for that card.

Three different engines with three different jobs. They are often confused, so: SomniScan — the deep pass over a night's waveform Where the Daily view draws what the machine recorded, SomniScan goes back over the high-resolution flow data itself and looks for what the machine's own scoring did not flag. Its output is a set of findings about a specific night with the evidence attached. SomniPattern — the pass across many nights A single night is noise; twenty nights is a signal. SomniPattern looks for repetition: events clustering at the same hour, a channel drifting week over week, nights that group into recognisable types. It answers "is this a pattern or was that one bad Tuesday?". Somni-UARS — the specific hunt for upper-airway resistance Flow limitation and airway resistance do not always produce scoreable apneas or hypopneas, which is exactly why they get missed. This engine looks at breath morphology for that signature rather than at the event count. What they all have in common They read the same imported data you can see. Nothing is inferred from outside your account. They produce observations, not diagnoses. A finding is a place to look, and a good thing to raise with your clinician — it is not a verdict, and it does not replace a sleep study. They are part of the advanced tier. Locked tiles say which one they need. Bring findings here if you want help reading them. Bring them to your clinician if you want to act on them. Nothing on SomniTalk is medical advice.

The Luna range is built by BMC Medical and sold under the React Health / 3B Medical brand, which is why the same machine has two names depending on where you bought it. Three card layouts turn up, and you select the card root for all three. 1. Luna G3X (and BMC G3 A20 / B20A on recent firmware) The card root holds files named after the machine's serial number — something like A31XXXXXXXX.idx, .evt, .set and .log, plus numbered waveform files .000, .001 and so on. You will probably also see nP3-… files (the machine's language packs) and a System Volume Information folder. All of that is normal. Select the whole card. 2. Luna G2S (the older Luna) The same serial-named files, but with a .USR file where the G3 platform has .evt. 3. Luna II / Hoffrichter POINT (ResVent format) A card with THERAPY and RECORD folders. The two questions we get most "My Luna G3X shows up as BMC Medical G3 A20." That is correct, and it is your machine. The device reports itself as a G3 A20; SomniCharts prints what the machine says rather than what the retail box says. Your data, charts and settings are complete — only the label differs. "My G3X card went to DropBox review from the phone." The Android app needs version 1.12 or newer to recognise the G3-platform layout. Update from Google Play and upload again, or upload the same card from the web app. Worth knowing: the G3 card format is newer than some other tools can read. If a different program refuses your card, that is not a sign the card is damaged. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Löwenstein (prisma series) data comes out of prismaTS, and there are two shapes of it. Both are supported, and you do not need to convert between them. A DCM folder exported from prismaTS — select the folder (or the card/folder that contains it). A dcm.zip archive — upload the zip as it is. Do not unpack it first; the importer reads the archive directly. Notes specific to these machines A zip that contains programs is normal. Löwenstein's own exports bundle vendor support files alongside the data. The upload scanner is built to expect that and lets the archive through — you do not need to strip anything out. The model is decoded from the file, not from the box. The prisma range covers CPAP, auto, bilevel and S/T modes, and the mode determines which channels and which pressure settings appear afterwards. A prisma bilevel will show pressure rows a prisma CPAP does not, and that is correct. Big exports. Long prismaTS exports can be large; if one exceeds the per-upload limit, export it in shorter date ranges and upload them one after another. They merge. Re-exporting the same range is safe — duplicates are skipped. If a prismaTS export is refused or lands in DropBox review, say which prisma model and which prismaTS version produced it. That pair is usually the whole answer. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

What to select: the card containing the P-SERIES folder — either the card root or the P-SERIES folder itself. That covers DreamStation, DreamStation 2 and System One. The question that comes up every week: "why do I have fewer charts than my friend?" Because the machine records fewer channels, and the app shows you what the machine actually wrote rather than drawing empty boxes. DreamStation 2, and the DreamStation 1 Auto CPAP models, record a flow waveform only — one signal, at a low sample rate. There is no mask-pressure waveform on the card at all. They also do not record tidal volume, respiratory rate or minute ventilation. Those exist on bilevel and ASV machines, not on these CPAPs. So on those devices SomniCharts hides mask pressure, minute ventilation, respiratory rate and tidal volume, and the statistics table shows the channels that exist: pressure, leak, snore, and inspiratory/expiratory time. Nothing is broken and nothing failed to import. A DreamStation CPAP simply writes less to the card than a ResMed AirSense does, and less than a Philips bilevel does. Other things worth knowing Model names. Cards identify the machine by a model number (the 500X/501X family and friends). Devices registered before the friendly-name work still display as their raw number — same machine, older label. Event types. Periodic breathing and variable breathing are real, separately reported events on these devices, not a lumped "other" category. System One cards import as well, with the older feature set of the machine. If your Philips card imports but a chart you expected is missing, say which exact model you have — the answer is nearly always the channel list above. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Select the card root. Not DATALOG, not a single month folder — the whole card. A ResMed card (AirSense and AirCurve 10/11, S9) carries: DATALOG/ — the nightly detail, one folder per date, holding the high-rate waveform and event files. This is the bulk of the card and the part that takes time to import. SETTINGS/ — your therapy settings as the machine recorded them over time. STR.edf — the summary file: one row per night, covering usage, leak, AHI and pressure statistics. This is what makes a long history import quickly even when the detailed nights are pruned off the card. Identification.* — what the machine says it is. This is how the importer knows the model. Practical notes The card prunes itself. Machines keep a limited window of detailed nights but a much longer summary history. If your charts show a year of trends but only a few months of detailed waveforms, that is the card, not the import. Upload the whole card each time. Re-uploading is safe — de-duplication skips everything already present, and the new nights merge in. Don't reorganise the card. Moving files out of DATALOG breaks the date structure the importer reads. Cards over 5 GB go up in batches; the batches merge automatically. Oximetry, where you record it on a compatible setup, arrives with the nightly data and appears on its own tiles rather than in the flow charts. If a card refuses to be recognised, send it through the DropBox fallback rather than reformatting anything — that is the route that gets a layout looked at. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

A profile holds one person's therapy data: their devices, sessions, charts and analysis. An account can hold several — a couple who both use CPAP, a family, or a clinic's patients. The numbers Every account includes two profiles free. A third or later profile is a paid add-on. The app shows you the extra monthly amount and asks you to confirm before your subscription is revised, and deleting an extra profile reduces the billing again automatically. Why the active profile matters more than anything else Uploads import into whichever profile is active. This is the single most common cause of "my data went to the wrong person". The active profile's name is shown at the top right — check it before you upload, every time. If you get it wrong, cancel the import inside the fifteen-second window rather than untangling it afterwards. Worth filling in when you create one The wizard's CPAP treatment step is optional, but two fields earn their keep: Therapy start date — when you first began PAP therapy on any machine. It is what lets the analysis tell early adaptation apart from a persistent pattern. Untreated AHI, if you know it from your sleep study. Both can be added later by editing the profile. Deleting a profile deletes its data. Permanently, including any stored analysis history for that profile. There is no archive to recover from. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

The short version: take the SD card out of the machine, select the whole card folder, and let the app do the rest in the background. 1. Make sure the right profile is active. Data always imports into the active profile — its name shows at the top right. A profile holds one person's therapy data; a fresh account starts with two included. 2. Put the card in your computer. Card reader or adapter, either way. Do not rename or move anything on the card, and do not tidy it up first — the folder layout is how the importer recognises your machine. 3. Open the upload dialog and pick the card root. In the New Look interface that is the Upload CPAP data icon in the right rail; in Legacy it is the upload section on the welcome page. The dialog tells you how many files and how much data it found. 4. Upload. Large folders go up in chunks of roughly 95 MB with per-chunk progress. Leave the tab open until the last chunk lands — navigating away discards the upload, and the browser will warn you first. Once the upload finishes you can go anywhere; the import runs on the server. 5. Let the import run. You get a fifteen-second Cancel window right after the last chunk, and a Cancel button for the whole import after that. A few months of data import in minutes; a multi-year card can take tens of minutes. You can log out and it keeps going, and you get an email when it finishes. Things that trip people up One upload at a time per browser. A second tab is blocked on purpose. 5 GB per upload. Bigger cards go up in batches — they merge automatically. "Everything was a duplicate" is de-duplication working, not a failure. Unrecognised folder? The app offers the DropBox fallback instead of importing garbage. Use it — that is how unsupported layouts get looked at. Vendor-specific card layouts have their own topics in Importing Data. Nothing on SomniTalk is medical advice.

The lounge is the room with no agenda. Start here. Everyone on this board has been told about sleep hygiene, and almost nobody has been told anything that survived contact with a real evening. So: what actually works for you? Not the poster advice — the specific, slightly embarrassing thing. The alarm that means "go upstairs" rather than "wake up". Putting the phone charger in the other room. A boring book kept solely for this purpose. A dog with strong opinions about bedtime. Anything goes here as long as it stays civil and stays legal. If a thread in the lounge turns into a genuine therapy question it will get moved to a category where it will be seen by the people who can help — that is a courtesy, not a telling-off.
