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 honest schedule is shorter than the leaflet and longer than "when it smells".

Daily (two minutes): wipe the mask cushion where it touches your face — skin oil is what breaks the seal and shortens cushion life. Empty the water chamber and leave it open to air-dry; standing water is the thing that grows.

Weekly (fifteen minutes): mask parts, tubing and chamber in warm water with a mild, fragrance-free soap; rinse well; hang to air-dry out of direct sun. Vinegar diluted in water is a reasonable de-scaler for the chamber if your water leaves deposits — rinse thoroughly afterwards. Distilled water in the humidifier prevents most of the scale in the first place.

Monthly-ish: check the air filter at the back of the machine; replace or wash it according to your model's instructions (some are disposable, some are rinsable — the manual says which). A grey filter is a working filter; a black one is overdue.

Never: bleach, alcohol, essential oils, or anything scented on silicone and tubing — they degrade the material and you breathe the residue. Do not put the machine itself in water; a damp cloth on the outside is all it needs.

Ozone and UV cleaners. As of our last check, the US FDA has not cleared any of them for CPAP equipment and issued a safety communication about ozone exposure and material damage; the major machine makers say use of an ozone device can void the warranty, and several specifically advise against it. Soap and water is what every manufacturer actually recommends. If a supplier is bundling one, you are allowed to decline it. How to Clean Your CPAP Machine, Mask, and Hose (Skip the Gimmicks)

Replacement schedules (cushions, tubing, filters) are a different question from cleaning — and that one is mostly set by your insurer or supplier, not by wear.

Data_Desk

Read them in this order, because each one only means something if the one before it is in place.

1. Usage — did the machine get the chance? Hours per night and nights per week. Most of the other numbers are averaged over the time the mask was on, so two hours of perfect data is still two hours. The usual clinical and insurance yardstick is four hours on most nights; the therapy yardstick is all of your sleep. How to Read CPAP Usage Hours and What 'Compliant' Really Means

2. Leak — could the machine do its job? A mask that leaks heavily cannot hold pressure, and the machine stops being able to tell what your airway is doing. Look at how long the night spent in large-leak territory, not the peak number — a thirty-second roll-over blip is noise; forty minutes is a fitting problem. Each brand reports leak differently (ResMed shows excess leak, Philips shows total leak), so compare against your own machine's scale. CPAP Leak Rate: What's Acceptable and How to Fix High Leaks

3. AHI — what was left over. Events per hour of use. The convention most clinicians use is "under 5 is treated", and most people on well-fitted therapy sit well under that. Two things matter more than any single night: the trend over a couple of weeks, and the spread — a quiet 1.2 one night and 6 the next says "something was different that night" (position, alcohol, a cold, a leak) more than it says "the therapy is failing". If the events are mostly clear airway rather than obstructive, that is a separate conversation worth having with your clinician. What Is a Good AHI on CPAP? AHI Ranges and Residual AHI Explained

4. How you feel. Not a number, but the point. Good numbers and a bad morning is a real and common pattern with its own list of causes. Still Tired on CPAP With Good Numbers? Reasons and Next Steps

What we will not do here is tell you what your pressure should be. The three numbers above, over two weeks, are exactly what to bring to the person who can.

It has a name — aerophagia — and it is common enough that every clinic has heard "CPAP belly". The air the machine delivers is meant for the airway; some of it goes down the oesophagus instead, and by morning it is in the stomach. It is uncomfortable, it is not dangerous in itself, and it is very often fixable — but almost always by the clinician or DME, not by the person in the bed.

What tends to make it worse: pressure sitting at the top of its range for long stretches, mouth breathing (an open mouth is a second route for air), sleeping flat on the back, a large late meal, and simply being new — the swallowing reflex settles for many people within a few weeks.

What the data can show you — and this is the useful part. Line up the nights you woke bloated against the overnight pressure trace and the leak line. If the bad mornings are the nights the pressure spent most of its time at the upper end, or the nights with long mouth-leak stretches, you have something concrete to bring to your clinician instead of "my stomach hurts". That is exactly the conversation that leads to a changed setting, a different mask type, or a comfort feature being switched on. CPAP Aerophagia: Why Your Stomach Bloats and How to Address It · Is Your CPAP Pressure Too High or Too Low? Signs and the Data

What people try, in rough order of how often it helps: a conversation with the clinician about the pressure range and comfort features (we do not suggest values here, ever); a mask or chin-strap change if mouth leak is in the picture; sleeping on the side or with the head of the bed raised; eating earlier; and patience in the first month. Antacids treat the symptom, not the air.

If it is sudden, severe, or comes with pain rather than bloating, that is a doctor visit, not a forum thread.

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.

It survives, and one timeline is exactly what you get — with two honest caveats about comparing brands.

How it works. Every brand writes its own card format, and SomniCharts reads each of them (ResMed, Philips Respironics, Löwenstein, BMC). Import the old card and the new one into the same profile; sessions are placed by their timestamps, so the day you switched is simply the day the chart changes colour, not a gap. Re-importing is safe: duplicate sessions are recognised and skipped, so you can bring the old card in again later without doubling anything. Do the old card first, and soon — a card that goes back to a supplier, or into a drawer, is the one history people lose. Switching CPAP Brands? Keep Your Data History Across Vendors

What compares cleanly across the switch: usage hours, nights used, the pressure the machine delivered, the overall AHI trend, humidifier settings.

Caveat 1 — event definitions differ. Each manufacturer decides for itself what counts as a hypopnea, how long a flow drop must last, and how it labels clear-airway events. A step in your AHI on the switch date can be the scoring changing, not your airway. Read the two halves of the timeline as two instruments, not one.

Caveat 2 — leak is reported on different scales. ResMed reports leak above the mask's intentional vent flow; Philips reports total leak including it. Side by side, the Philips line sits higher for the same seal. The charts label which is which; do not read the jump as a worse mask. CPAP Machines & Devices
