More than the smiley face

CPAPGeeks reads everything your machine wrote to the card and lays it out night by night. See what happened, when it happened, and how it changes as you adjust your mask or routine.

A night's summary: events per hour, hours used, leak and pressure, with a count of each event type.

Every number from the night

Events per hour, hours used, leak and pressure, plus how many of each event your machine flagged.

Charts zoomed into a two-minute window around a central apnea, showing flow, pressure, leak and breathing rate.

Zoom into any event

Pick an apnea from the list and the charts jump to it, so you can see the breaths before and after.

A list of seven nights, each with hours used and events per hour colored by how high it is.

All your nights in one place

Every night on the card, newest first, with the number that matters most colored at a glance.

From SD card to answers in a few minutes

  1. Take out the SD card

    It's in a slot on the side of your machine. Put it in your computer with a card reader.

  2. Drop the card into CPAPGeeks

    Choose the whole card. We read every night on it, and only add the ones we haven't seen before.

  3. Read your nights

    Open any night to see flow, pressure and leaks, or compare the last few weeks side by side.

See the apnea, not just the count

An AHI of 2 tells you how many events there were. The flow chart shows you each one: the breaths flattening, how long it lasted, and how the machine answered.

  • Obstructive, central and unclassified apneas, hypopneas and arousals, each in its own color
  • Pressure and exhale pressure on the same timeline
  • Leaks that line up with the moments your mask shifted
Obstructive Apnea, 11 s
Flow from a sample night. During the apnea, airflow nearly stops for 11 seconds, then the machine raises pressure to keep the airway open.
A sample weekEvents per hour (AHI), with hours used under each night

Under 5 events per hour is the usual therapy target. Your clinician may set a different one.

Spot the pattern across nights

One rough night is noise. Three in a row after a new mask is a pattern. Put your nights side by side and watch your events, hours and leaks change as you make changes.

Questions

Which machines work with CPAPGeeks?

ResMed AirSense 10 and 11, AirCurve 10 and 11 (including ASV), and the S9 series, plus Löwenstein prisma, React Health / BMC and Sefam S.Box machines (in beta). Philips, Fisher & Paykel and others are coming next. The machines page has the full list.

How do I get the data off my machine?

Take the SD card out of the side of your machine, put it in your computer (most laptops need a small USB card reader), and drag the whole card into CPAPGeeks. Put the card back afterward so the machine keeps recording.

Who can see my data?

Only you, unless you choose to share a link with your doctor. Your files are encrypted in storage, we never sell data, and you can delete your account and everything in it at any time. The Privacy Policy has the details.

Will CPAPGeeks tell me what settings to use?

No. CPAPGeeks shows what your machine recorded so you can have a better conversation with your sleep clinician. Talk to them before changing your settings.

Can I use it on my phone?

Yes. CPAPGeeks works in any modern browser on phones, tablets, and computers, and you can add it to your home screen. Uploading is easiest from a computer with an SD card reader.

Do I need an account?

No. You can open your SD card and read every night without signing up. Create a free account when you want your nights saved, so they're there next time on any device.
