What's happening on this Chart??

If you insist on running in a range of pressures, I'd limit the top to 17. Otherwise, I'd also suggest running in CPAP mode at either 16 or 17. (see which one gives the best results).

That is true! I experienced that last night after re-adjusting all the straps. There appears to be a fine line between too loose (allowing the chin strap to pull the pillows away), and too tight ("crushing" the pillows so they don't flex enough to maintain seal.)

However, last night was anything but typical with the severe storms we had (along with most of the eastern US!). Lost power twice*, resulting in the night's data being spread across three separate pages! Not to mention the intermittant lightning, thunder and rain pounding the roof to wake me up...

I also agree with those who suggest CPAP mode--for the reasons they named--but also so I'm not asking the mask to deal with changing pressures and not leak. I love the comfort of the Opti, but it appears to be touchy about adjustments; and throwing oscillating pressures at it doesn't help.

*How does the machine know the time and date? Obviously an internal clock, but *I* didn't set it, and I don't see that option on the clinician's menu. It's apparently on battery and set at the factory, but how do they know what time zone it's destined for?

Looks like a few more nights of experimentation are in order.

"Magic"......

Unfortunately, the internal clocks are set at the factory for GMT. Then, when you download the data into your computer, the Encore software takes the time zone in the computer and converts it in the data files.
My biggest gripe with the Respironics machines is that the clock is not user set-able......AND, they lose time.....about a minute or so a month. I'm not quite sure what happens when the battery goes completely dead. I've seen posts where the user reported dates on the reports of like 1998 or maybe a little later. Kind of like in computers when the battery on the motherboard dies and it reverts to the BIOS date. Problem is, with these machines, it takes a sophisticated cable that connects the smart card slot to the computer and some specialized software to correct the dad-gummed thing.

All THAT just to get the time??? Heck, when it's operating, my watch is always right there next to it on the nightstand. You'd think it would just sneak a peek rather than go to all that trouble!

That seems like an incredible amount of "over-engineering" to me...
