Philips foam issue - Sensors might be inaccurate ?? - DaveCar - 08-20-2021
So I'm layin' there this morning wondering why the Resmed that Im using now seems so much quieter, my numbers are better, and I dont feel like I have as much pressure in the mask compared to the DS (I typically use around 16 in cpap mode).
Could my DS circuit board sensors be coated in PE-PUR deposits and was giving questionable therapy ?
To be clear, Im not talking a "night and day" difference, but it sure seems noticeable.
There's a handful of sensors monitoring very delicate differences in pressure to detect events and adjust flow/pressure.
Users have found oily/sticky/particulates in airboxes, and thats where the sensors reside.
So, perhaps just removing the foam isn't a 100% solution to get a machine back to "new condition" ??

I've used both, and got rid of the DS. I too found the ResMed to be much quieter. Breathing also seemed much more natural w/ the ResMed. I've been told the 2 companies have different algorithms and also the way they handle pressure support/relief (PS/EPR on ResMed, Flex on DW) is very different.
The DW always seemed to be forcing air down my throat whereas the ResMed seems to be a more natural airflow. I would not have stayed with therapy if the DW was the only option. But I am probably more sensitive (and a very light sleeper) than most.
I gave my backup ResMed (Autoset) to a friend who had been on DW and told to stop due to the recall. She says she is sleeping soooo much better on the ResMed.
As for the foam and sensors .... I have no idea.
