First Night on APAP--what does it mean?

[SailingAway]

Well, with the third night in the books, I went back to the Airfit P10. Took your advice and went to the larger size and although it took a little more maneuvering to initially get it situated, I slept through the night. My AHI crept back up to 4.8, but I slept well and feel rested. No sore nose again, so all in all a good night. I think this combo will work well and I'm sure I'll get more used to it as time goes by.

For some reason last nights download to the SD card didn't produce any graphs in SleepyTime. It did show graphs in ResScan, but only had the summary data in SleepyTime. It showed some funky data on some of the detail. Like zero leakage and zero flow rates. It appears something didn't record correctly. I imported it a second time and SleepyTime reported AHI of 0.0 while the display on the S9 said 4.8 and in ResScan 4.8. This of course screwed up all the average date, etc. I found an option to delete the current day, which corrected the average/composite data.

Not sure what's going on there. I realize ST is still in testing, etc. Just don't want it to corrupt my average data, even if a single day is messed up.

A final question, when and how do you delete data on the data card? No where near full, but haven't seen that addressed anywhere. I always lock the SD card prior to downloading, then unlock when I put it back in the S9.

Thanks

According to the chart presented, most of the apnea events are happening above a pressure of 9 cm/H2O not below it. Second, the charts for flow limitation and snore are right there along with the rest.

Payton, what are you suggesting here? That the pressure is too high?

Sorry, I'm trying to get up to speed on this stuff.

No. Actually only pointing out what appear to me to be observation errors. I generally agree with the recommendations made.

I know Payton A doesn't agree, but that is a good minimum pressure for you. ........

Actually, I agree with that statement.

You don't do that. The S9 will manage the number of days worth of graphical stuff kept on the card. Actually, if you "touch" a file on the card, the S9 will get all cranky about it and insist on re-formatting the card. At which time it will also write all the compliance stuff back out to the newly formatted card.

Good job last night. I think you've got this thing figured out. Let's see what the data shows after tonight and then think about raising the minimum pressure a little bit.
