RE: Resmed Tech Support
I'm not aware of Resmed pushing any firmware update since about 2015 for a humidifier issue. That was widely publicized. If your device lost settings, it may have been a power surge or even your DME pushing a setting change, but very unlikely it came from Resmed. I have mixed feelings about the FDA since they seem to default to the pharmaceutical companies rather than protection in recent years. Even with the Philips fiasco, it took them 3-years to go beyond the voluntary recall and actually enter a consent decree. Meanwhile, there are a half-dozen Chinese manufacturers of CPAP and BPAP that are doing so under an Emergency Use Authorization (EUA), without the normal rigorous test ng and review that normally goes into these devices. I wonder how that will work out?
RE: Resmed Tech Support
I don't have a "DME" (whatever that is!). I bought my machine 3 months ago directly from ResMed here in the UK and I can assure you that their technical support is RUBBISH!
I have had occasion to contact them twice with problems and each time they have demonstrated that they have clearly been trained to ignore any request for help. They consistently answer random questions I have NOT asked (usually with "we can't help with that") and carefully ignore any question I have actually asked.
