ResMed AirSense 10 changes?

I started using an AS10 about 2 years ago and it really helped a lot! Increased energy, less naps, better mood, etc.

I have noticed that in the last 6-10 months, though, that these benefits have decreased and that the machine seems to be working differently. I wanted to see if anyone else was noticing changes with the behavior of their machine.

-settings - autoset from 8-20

• when I first got the machine, it was much more responsive when I took off the mask and when I would hold my breath, simulating an event where my breathing stopped in the night. It would ramp up significantly with multiple “whooshes”.

• now my machine does not do this. It simply keeps going at its set pressure and eventually will turn off after about 5 seconds if the mask is taken off.

This lack of auto response seems to have coincided with a decrease in effectiveness. I wanted to see if anyone else had experienced the same thing and if anyone knows if ResMed changes their software at some point.

I am not aware of any significant changes in the firmware of the A10. There is a setting in the Clinical Menu that slows the response of the machine to events. It apparently was not on some of the original machines. Not sure if it was an over the air firmware update, or if at some point the newer machines came with it. I have never tried using it.

On the more simple side, have you been replacing your air filter regularly? That might account for some loss of maximum flow.

I have only been using mine for just over a year now, but have not noticed any changes. My wife is at about 4 year on her ResMed S9 model and seems to be having no issues with it.

The best way to monitor what the machine is doing is to download SleepyHead or OSCAR and use the software to monitor the results in detail. You will be able to see when you are having events and evaluate to some degree if the machine is behaving properly in response to the events.

Hope that helps some
