First try at posting stats for review

RE: First try at posting stats for review
Thanks for that info. I've been trying to figure the algorithm for a while. I'll verify my min pressure later today, I can't remember if I used 8 or 8.5 (up from 7). I do know that I could definitely feel the difference.

I'll give my current settings a week or​ so, and see where things settle out before I try another tweak.

I thought there was a setting that would program the APAP to start at whatever the average pressures​ were, but I didn't see it last night. I didn't​ have a manual nearby, either, so I couldn't​ find that value.

RE: First try at posting stats for review
there is something that is called 'smart start' I think, and this collects the last 30 hours of usage and calculates a 'best start pressure', but I don't believe it is the 90% pressure. anyway it takes several days to get a new starting pressure.

the forum consensus is more aggressive, as you can tell.

Sorry, I was under the impression that Smart start simply starts the machine when you put the mask on and start breathing into it.  The machine will then start at the pre-set minimum pressure that is already set up on the machine. Is that not correct?

RE: First try at posting stats for review
There is an "Auto Start" that turns it on automatically.

I did find the clinician's setup:

Opti-Start:  

"This feature starts an Auto-CPAP therapy session at a starting pressure that is closer to the previous session's 90% pressure, in order to reduce the likelihood of any residual events at the beginning of a therapy session.  You can enable or disable this feature."


edit:


By the way, if anyone wants a complete copy of the Dreamstation Provider Manual, I found one here:

Marillion,
You are correct. Smart Start is Resmed's name for the autostart feature. I believe quiescence was referring to Opti-Start. P-R uses this feature to start the CPAP at the last best pressure. It's one of those, "Whose on first". type of things. I guess it would be too easy to standardize their terminology.

I will verify the Opti-Start setting on my machine later tonight.

Verified that Opti-start is on.

Flex is off. That function lowers air pressure on exhales?

RE: First try at posting stats for review
if flex is off = less reduction in pressure at the beginning of the exhale.

flex is a flow-based variable easing of pressure. see link below for more detail.
