AHI 131 !! - Help me understand my SleepStudy & CPAP results

[Kenwood]

2nd night with the the new PR S1 750 BiPap Auto machine.........New record AHI of 0.43

The EPAP line had some action last nite from yesterday's unusual straight line - thats look's more normal now. Also something new on this chart that I've never had on any of my charts, maybe its new on the 750? My chart now has VS (instead of just VS2) and its also in my flow rate chart too? I slept really great last night. Woke up around 7:30am'ish and had some tossing and turning trying to fall back to sleep. Same thing around 10am'ish till I got up. So there's some SWJ (sleep wake junk) in there. Another perfect leak line night for the Aloha.

I guess that the flat EPAP line was a none exciting snore night.

There are 2 kinds of snores that get flagged. I can't remember the explanation between the two...drat. Robysue had a good explanation a while back. To be honest I just didn't pay a lot of attention to it because I sort of figure...what will be ..will be and let the machine deal with it or if it can't...give it some help with minimum pressure or in your case EPAP.
I will see if I can find the explanation. I think one the machine will respond to and the other it won't...but I can't swear to it.

Main thing...you slept great. And yes..now the EPAP line looks like it did some work last night like it is supposed to.

I felt I slept extremely great last night...good think I didn't look at my report till just a few minutes ago.
Last night was bad coyote ugly night. AHI 8.33 and CA index was only 0.45.
REM events return with a vengance...the ones that I see sometimes need 18 cm pressure and I was using the 660. and it only hit them with 14 IPAP and 10 EPAP...obviously they thought it was a little slap on the wrist and proceeded to have a party and invite lots of friends.
This would be extremely rare time on auto bipap for me ....I would see really high pressures like that maybe once every 2 or 3 weeks.

So this is why I am a poster child for Auto adjusting pressures. I knew it was going to jump up and bite me in the butt sooner or later.

AHI has been high the last 2 nights...I also have had the heated hose attached these last 2 nights...Hmmmm. Don't know if that matters or not.
Anyway...I feel great...went fishing today in the rain. Had a great time. Never got drowsy till after supper that our friend mom cooked for us.

I will try to update my poster child thread so that everyone can see that even Pugsy has a coyote ugly night every now and then.

...and early in the week you had a perfect ZERO AHI night. Ebb & Flow

[Pugsy]

Yeah, the aliens paying special attention lately.
This isn't the first time and I know it won't be last.
Hey, at least if they want to mess with me I feel good the next day...I went fishing today..in the rain...great fun.
Was digging up worms...dug up a baby snake...cute little bugger but rain off before I could catch him and put him on the hook.
Boy does my back feel it. All that walking and standing. Next time I am taking a camp chair.

Hey Pugs, here's some advice for you... . please get back on your Auto, you're making me nervous!!

[Pugsy]

Hey Pugs, here's some advice for you... . please get back on your Auto, you're making me nervous!!

I am tired tonight...too tired to get it out and set it up. I increased my pressures tonight and will get it one more night on the heated hose. Then I will set the 660 aside. I have a friend that has been balking about doing the sleep test. I think I will use it on him just for fun. Heck, maybe he will want it.

You know when I was using the 750 in Fixed bilevel mode...I never had these bad reports event at 8 EPAP and 12 IPAP. I was looking at some of my old reports...no where near ugly. Something is different and I don't know what. I am going to bed now....standing out fishing in a pond in the middle of the rain and no chair to sit it has my back telling me what a foolish old woman I was.

3rd night with the the new PR S1 750 BiPap Auto machine.

Felt soooo good to sleep for 10 hours, although my back is a little stiff. This weekend was the most sleep I've gotten since being on CPAP. Since I only get about 5 hours during the week (start work at 6:30am), its nice to get caught up on my sleep again. Woke up in the early morning to a my nasal pillow leaking - but that was me making it leak sleeping on my face. Looks like the IPAP went up higher last night as I also had a couple snores (max 9.0 on chart). But even with a two hour period of a leak, my AHI 0.50.

Saturday night's data - Night #3 using new BiPAP AUTO with Aloha Nasal Pillow

[Pugsy]

With the 750 machine the large leak territory begins up around 90 L/min. When in doubt just use EncoreBasic. It will flag large leak time for you.
The worst you did was that one hour between 60 and not quite 75 L/min. Not nearly as pretty as the other nights but we don't get perfect all the time.

Still a great night. You can definitely see the machine responding to the snores and that little bit of Flow limitation.
You can also see how you need over 20 sometimes but not all the time.

I don't know that those little bit of snores are worth worrying about. This is where I sometimes think close is good enough when I say I am sleeping great and feeling great...I don't care if the reports aren't picture perfect. We already know with using the bipap pr with EPAP of 17 pretty much killed the snores and flow limitations but I don't know if I would want to increase EPAP just yet (if ever) just for a few snores or FLs. If it were me, knowing what I know about how my body responded to bilevel and the fact that over a period of a few weeks the events reduced on their own with zero changes...I would probably still give it a wait and see approach as long as I was sleeping well.
Going to be your call really.
If you do decide you want to kill a few more snores...with EPAP..go up slowly with 0.5 at a time. Sometimes just a little does a lot more than you might anticipate.

[Kenwood]

It's very interesting seeing how the Auto responses to what's going on with me. I'll continue to post my charts daily this coming week and then see if my pressures need a slight bump or not...next weekend. Thanks Pugsy!

4th night with the the new PR S1 750 BiPap Auto machine.........New record AHI of 0.32

Another really great night. Perfect Aloha leak line - so I've moved the Leak chart down and brought the snore chart up. First night with some snores that were above 2 or 3.

Sunday night's data - Night #4 using new BiPAP AUTO with Aloha Nasal Pillow

[Pugsy]

Nice boring report again. I think if me..if the snores persist.. 0.5 cm more EPAP...that's only change.
Just because I am a bit anal retentive about snores that are persistent and consistent.
Random..not so anal about. Especially since I saw what 17 EPAP on the Pro would do.
Though it probably is not a critical issue.

5th night with the the new PR S1 750 BiPap Auto machine... little higher AHI last night.

Had 6 Hypopnea's and 3 Obstructive Apneas last night. I had a REALLY bad day at the office yesterday. I went to bed wondering if my bad day would have an effect on my sleep. Although the numbers are not bad, the AHI was above 1.0 for the first time in numerous days. I'm going to hold off upping the EPAP by 0.5 cm until the weekend. I want to see a week of stats at these settings on the Auto so I have a good sampling of days for future reference.

6th night with the the new PR S1 750 BiPap Auto machine.

Had a good cluster last night of Hypopnea's around 1am and surprised that IPAP didn't try to spike up.

Tuesday night's data - Night #6 using new BiPAP AUTO with Aloha Nasal Pillow

[Pugsy]

Had a good cluster last night of Hypopnea's around 1am and surprised that IPAP didn't try to spike up.

The machine did sit back and twiddle its thumbs didn't it? EPAP nor IPAP did anything.
Don't know why unless the normal warning signs of a potential collapse of the airway didn't occur. Remember the machine responds to the warning signs and not the flagged event. Once the event gets flagged the machine sits back and twiddles its little thumbs until the event is gone and normal air flow resumes.
Did you happen to have very many pressure pulses (those little red squares) show up during those hyponeas? You would have to zoom in to see them.
Maybe the hyponeas were leaning more to the central side of things and the machine won't respond at all to centrals.
