bipap vs autoadjusting bipap diff

-SWS wrote:Thanks, Den!

Another question for the gang. Does anybody know if there are any functional differences between the tank auto BiPAP and the current M-Series model? Or was that a form-factor transition only? Thx again.

I've used both the older non-M ("tank") BiPAP Auto and the M BiPAP Auto. Same feeling to the treatment with both, and same data results with both. And same well "rested" mornings with either one.

Den, Tks for that update re BiFlexbeing active in Auto mode on the new M-series...


#2 there is one test that will confirm to me what is probably inside. When an M-Series Bipap Auto is turned on,
does it delay for a couple of seconds (while making a motor running up sound sound), make a mild 'thump' noise
then start pumping air, *or* does the air flow immediately you push start. It it starts immediately then it is most
probably as I said, a variable speed motor with no airvalve which in turn would be a complete redesign.

I have the M series Bi flex, with the blue lights (hey, I like them, gives that grotto look to the bedroom! )
When it turn it on (the machine that is), the airflow starts immediately. So, variable speed motor?

When I cleverly changed the menu into clinician or DME mode, thanks to the tip to unplug, hold 2 buttons, and replug, one of the choices I now have is

"Bilevel Auto Bilevel"..... I have Auto Bilevel selected. Since I didn't understand most of the above thread, just hung in there in case something I needed showed up, can someone tell me what the difference is between the two, and reasons to select one or the other? I'm a newbie, 8 days today!!!! and feeling better, plus saving up for the software!

Chris,

Thanks for the confirmation - yes it seems the M-Series BipapAuto is a complete redesign.

The fact is all vendors are moving over to using variable speed motors as they reduce the
cost of manufacture & keep the products competitive. Each manufacturer has challenges
when they redesign their equipment & as we have seen over the years, eventually get the
glitches (such as the M-Series humidifier problems & motor whine) sorted out. Resmed
had their share of whine problems (S7 & Vpap III models) plus the infamous power cord
recall on the early S8 models.

As a buyer we just need to be sure that what we are being sold is the stable model of a
particular product rather than an earlier problem unit.

One good reason to buy new machines & to buy them from a reputable supplier like our
host cpap.com as if we have any issues they will be there to support us.
