ResMed All models code 21
No approved translation for this record yet; showing the original text.
Meaning
Error 21 means the AirSense 10 detected a sustained leak that blew past what it could compensate for. ResMed defines a large leak as more than 24 L/min above the mask's normal vent flow. Once that threshold is crossed and stays there, the machine can't hold your prescribed pressure and logs the error.moderatebeginner
