I think I may have an oxygen deficit at night when I'm sleeping on the Cpap and will get check for that next week
The older machine I have has been on the road with me for almost two years. Broken down and traveled with about 40 times.
I wonder if the wear and tear could have caused some malfunction. What's the best place to get a machine checked out and serviced or refurbished. Can they go back to resmed?
Does anybody know
If the older machine was an S9 Elite and your new machine is an S9 Autoset, then perhaps the self-adjusting capability is helping.
If the older machine was an S8 model or an S9 Escape Auto model and your new machine is an S9 AutoSet then that may explain it. The S8 AutoSet and the S9 Escape Auto do not have the "Enhanced" AutoSet algorithm used in the S9 AutoSet and S9 VPAP Auto.
If both the older and newer machine have the exact same model name, then I am surprised the new one works better (if using same pressure or pressure range).
I think most firmware changes are only to adapt to newer/cheaper components, not to change the treatment algorithms, and I think there usually is no benefit to upgrading to a newer firmware version, if available.
You can call ResMed customer service and give them the serial numbers of your machines and they should be able to help you understand your options.
If you wanted your old machine checked out by resMed it would need to be sent to ResMed by a Durable Medical Equipment (DME) provider. ResMed does not accept machines for repair directly from end customers, only from DMEs. Can be any DME; does not need to be the original selling DME. But before you consider doing that, investigate prices for used equipment available online at places like Supplier #2
. A used machine in good condition may be a better deal than paying for a check-up or repair.
