[Treatment] Koala1 - oscar data, first impressions
#71
RE: Koala1 - oscar data, first impressions
Another few days on minimal pressure of 8.0 and A Flex 3
I feel better on Flex 3, as it seems the AHI levels are also more stable on it.

However with increasing pressure it seems that CA events also appears more frequently.
Its marginal but its there.

Overall last week was the best till now. Stable, with AHI around 1.64 on average.

I still want to get to know what is influencing my events and I am going to try
1. Mouth Guard - lower jaw regulation
2. Somehow stop myself from sleeping on my back - tried already but failed miserably
3. Nasal dilator 

I have attached 2 screens from 7/5 and today. Both similar but today I have a bad day. 2 days ago was perfect.

I don't see much difference in data, and even there is less de-saturation events today.
On the other hand, pulse change events today 275 vs 186 2 days ago.

It may influence how I feel, or is there anything else in the data that I dont see?

Nasal dilator + dreamwear nasal mask
Big fail, ahi over 3.0 
CA around 1.0, the biggest so far
Obstructive didn’t change 

I’ll go back to nasal pillow and try mouth guard

Did you feel comfortable and well rested or not? Comfort is still first in importance.

I’m not rested.
I’m going back to proven set up tonight.

Anyway. Yesterday I had ahi 1.1 and still was bad until like 2pm.
I try to find correlation between pulse change, flow rate and how I feel during the day.

Quick update - will share screens after few more nights.
I changed min pressure to 8.5 from 8
Not much but after two nights I had AHI of 0.4 and 0.8.

Hope it will stay around those numbers

RE: Koala1 - oscar data, first impressions
So it seems that min pressure of 8.5 takes good care about Hypopnea, but I have some CA.
Well those comes and goes. Probably when I get used to 8.5, CA will be lower.

Now I could see that with Hypopnea back there is still Obstructive on the same level as always.
Few days ago I was sleeping in Cervical Collar and obstructive was 0.
I am not sure however that tucked chin is a cause of Obstructive.

I will follow this lead and sleep in collar as well as I will try not to sleep on my back.

I am surprised by charts from last two days though.
Flow rate and Tidal Volume is limited on two occasions.
Tidal Volume as low as 110.

I wonder what may be the cause , and what it is in the first place.
Have you experience such limitations?

Quick update - screens later.

With cervical collar today app shows AHI 0.1 !
That would mean collar eliminated obstructive like last time I wore it and I had no centrals.

As mentioned in another thread. I still will try Static pressure mode for some time to see how CA behaves.

RE: Koala1 - oscar data, first impressions
CA can come from 2 main things, 1 is that they're pre-existing in that they'd appear before CPAP therapy on a diagnostic study, or 2 can be caused by higher breath efficiency that flushes CO2 out faster than your body is used to.

What rate are your CA showing in OSCAR? The .27 or so I've seen above isn't worth any effort to combat. That low a level shouldn't affect sleep.

RE: Koala1 - oscar data, first impressions
It’s inconsistent and yesterday it was 0.5 with overall AHI 0.75

It’s just few days since I changed pressure to 8.5 but CA numbers are higher.
On the other hand Hypopnea is gone so I don’t want to lower pressure.

As you say 0.2-0.3 probably is not worth pursuing. Even more if it is not emerging every day.
I just want to get more insight on how my body response to CPAP treatment and checking static pressure seems like next move.
Should loose anything. Just get more info.
