Step-by-Step Upload
- 1

What AirwayLab Reads From Your AirSense 11
Flow waveform (BRP.edf) — breath-by-breath flow data, though the EDF header format differs from AirSense 10
Session summary (STR.edf) — machine settings with updated signal naming
Device info (Identification.json, or SETTINGS/CurrentSettings.json on some cards) — device model identification
Tips for AirSense 11 Users
AirSense 11 AutoSet and AirSense 11 Elite are both fully supported for CPAP/APAP flow limitation analysis (Glasgow Index, WAT, NED).
Therapy mode and settings are read from the standard STR.edf signals. In AutoSet/APAP mode the pressure range is deliberately not displayed yet: the machine reports a single value we cannot confidently label as min, max, or average.
The AirSense 11 uses the same SD card slot and DATALOG folder structure as the AirSense 10.
ResMed's myAir app uses cellular upload. The SD card data is more detailed than what myAir shows.
Troubleshooting
My AirSense 11 didn't come with an SD card
Insert a standard full-size SD card, and the machine will start recording detailed data from the next session. Data is not retroactive — only nights after the card is inserted are recorded.
AirwayLab says "No EDF files found" for my AirSense 11 card
The exact message is: 'No EDF files found. Make sure you selected the SD card root, not a subfolder.' It means your selection holds no recorded nights. Selecting just the DATALOG folder works fine if it has data, but you'll be missing settings and device details, since STR.edf and the identification file sit at the SD card root, not inside DATALOG. Select the whole card to get everything.
Which files do I need to copy from the AirSense 11 SD card?
Copy the whole SD card and select the card root folder in AirwayLab. It needs the full folder structure to group sessions into nights.
