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.tgt) — 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).
Settings extraction (pressure, mode) works via the standard STR.edf signals.
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.
For detailed instructions on finding and accessing your data files, see the step-by-step AirSense 11 SD card guide.
Troubleshooting
My AirSense 11 didn't come with an SD card
Some AirSense 11 models ship without a card. Buy any standard SD card (2GB or larger, FAT32 formatted), insert it, 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.
All analysis runs in your browser. Your AirSense 11 data never leaves your device unless you choose to share it. The code is open-source (GPL-3.0) and publicly auditable.
