The ResMed AirSense 10 AutoSet is the most widely used CPAP machine in the world. It records detailed breathing data every night -- flow waveforms, pressure changes, leak rates, respiratory events -- all saved to a standard SD card.
Most people never look at this data. The machine's screen shows you AHI and usage hours, and that's it. But there's far more on that card than what the screen tells you.
This guide walks you through getting your AirSense 10 SD card data into AirwayLab, step by step. No technical knowledge required.
What You'll Need
Your ResMed AirSense 10 (any variant: AutoSet, Elite, or CPAP)
A computer (Mac, Windows, or Linux -- not a phone or tablet)
An SD card reader (if your computer doesn't have a built-in slot)
That's it. No software to install, no accounts to create.
Step 1: Find the SD Card Slot

The SD card slot is on the right sideof your AirSense 10, near the back. There's a small flip-up cover (some models have a rubber flap) that protects the slot.
If you're looking at the machine from the front, it's on the left side as you face it. The slot holds a standard full-size SD card.
Tip
If you've never opened this cover before, it might feel stiff. That's normal. Lift it gently with your fingernail.
Step 2: Remove the SD Card Safely
Power off your AirSense 10. Unplug it or hold the power button. This prevents data corruption.
Open the SD card cover on the right side.
Push the card in gently-- you'll feel a click, and the card will spring out slightly.
Pull the card out.It's a standard SD card (not micro SD), the same type used in cameras.
Don't worry
Removing the SD card does not erase your data, reset your settings, or affect your machine's operation. Your therapy settings are stored in the machine's internal memory, not on the card. You can put it back whenever you're ready.
Step 3: Connect to Your Computer
Insert the SD card into your computer's SD card reader. If your computer doesn't have one, any USB SD card reader will work -- they cost about $8-10 and are available from any electronics shop.
Once inserted, the card should appear as a removable drive. On Mac, it shows up in Finder. On Windows, in File Explorer.
Step 4: Understand What's on the Card
When you open the SD card, you'll see a folder structure like this:
SD Card/ ├── DATALOG/ │ ├── 20260101/ │ ├── 20260102/ │ ├── ... │ └── (one folder per day) ├── SETTINGS/ ├── Identification.tgt └── STR.edf
DATALOG folder
Your nightly session data. Each subfolder contains EDF files with flow waveforms, pressure data, leak rates, and event annotations for that night.
STR.edf
A summary file with daily statistics (AHI, usage hours, leak averages) for every night on the card.
SETTINGS
Your machine's configuration. AirwayLab reads this to understand your therapy mode and pressure settings.
You don't need to understand EDF files or open individual folders. AirwayLab handles all of this automatically.
Step 5: Upload to AirwayLab
Open airwaylab.app/analyze in your browser.
Click “Upload SD Card”.
Select the entire SD card or just the DATALOG folder. Either works -- AirwayLab finds the right files automatically.
Wait for analysis. This usually takes 30-60 seconds depending on how many nights of data are on the card.
Your data stays in your browser
Nothing is uploaded to any server. AirwayLab processes everything locally using your computer's processing power.
Step 6: What You'll See
After analysis, AirwayLab shows you a dashboard with:
Nightly summaries
AHI, usage, leak rates, and pressure data for each session.
Flow limitation scoring
The percentage of breaths with partial airway narrowing that AHI misses.
Breathing pattern analysis
Regularity, periodicity, and stability of your breathing across the night.
Trend views
How your therapy metrics change over days and weeks.
This is informational data about your breathing patterns. If you notice anything you'd like to understand better, discuss it with your clinician.
Putting the Card Back
When you're done, eject the card safely from your computer (right-click > Eject on Mac, or “Safely Remove Hardware” on Windows), then slide it back into your AirSense 10. It clicks into place.
Your machine continues recording as normal.
Frequently Asked Questions
How often should I check my data?
That's entirely up to you. Some people check weekly, others monthly. The SD card stores months of data, so there's no rush.
Will removing the SD card affect my therapy?
No. Your AirSense 10 continues to provide therapy without the SD card. It just won't record detailed data until the card is back.
My SD card is full. What do I do?
The AirSense 10 uses a 4GB SD card. When it fills up, it overwrites the oldest data. If you want to keep historical data, copy the DATALOG folder to your computer before the card fills up.
Can I use a different SD card?
Yes. Any standard SD card (2GB or larger, FAT32 formatted) works with the AirSense 10. Format it as FAT32 first.
