One practical addition: before the old machine leaves the house, pull the card and also note the mask model and the pressure range from its settings screen — the card holds the nights, not always the context. Six months later, "why did my leak look different back then?" is a much easier question with that written down.

The myAir score is honest about one thing and silent about the rest, and the published breakdown explains both reactions above. What it is made of (ResMed's own scoring): up to 70 points for usage hours, 20 for mask seal, 5 for events per hour, and 5 for the number of mask on/off events. So a 100 says, almost entirely: you wore it all night with a decent seal. That is genuinely good news — it is the foundation everything else needs — but it is 70 % a diary entry about hours. And a bathroom trip costs you points in the on/off bucket, which is why a 71 can be a perfectly fine night. What it cannot see: flow limitation (the airway narrowing that does not quite become an event), arousals and fragmented sleep, position, how the events clustered (ten in one bad hour reads the same as ten spread thinly), the shape of the pressure through the night, and anything about oxygen. All of that is in the detailed data your machine writes to its SD card — it just is not in the app. How to Read Your ResMed myAir Score (and What It Hides) · myAir & DreamMapper Limitations: Why Your CPAP App Isn't Enough So when the score is 100 and the morning is bad, the score has done its job (you used it; it sealed) and the next question is in the full data: OSCAR, SleepHQ, SomniCharts — any of them will show the night the app summarised into a single number. The list of reasons people feel rough on good numbers is real and worth reading before assuming the therapy is wrong. Still Tired on CPAP With Good Numbers? Reasons and Next Steps And if the detailed data looks clean too, that is important information in itself: it points the conversation with your clinician away from the machine and toward sleep itself.

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.
