Not the Best Night, a Bit Odd

What is a Zeo?

With a ZQ of 76 I would think I would not feel so groggy... Ugh. Some hours awake now today, I feel so tired... the foggy type of tired, not the "I'm exhausted" type, my body is perky, my brain is not. After 7 weeks of xPAP, I had hoped the grog would have gone away. I guess I have a lot of catching up to do after years, maybe decades, of deprivation. (Patience, patience, have, must I).

Hi NotSleepingBeauty!

A brain wave monitor thingy. It tells you about what your sleep stages are during the night, how long, statistics, coaching, etc.

What I have: Bedside model (got it yesterday, $122 on Amazon)

I wonder if those clusters of OA's are positional.

I'm guessing yes. My AHIs, like most people, are high when on my back and also high in REM. In REM, on my back, during the sleep study they were technically considered "severe" (AHI of 48 I think).

Here's a zoom of them from last night. You can see a regularity to them.


You can also see the S9 not really scoring them correctly, in my opinion. They were scored too soon (they lasted longer than the marker shows at least).

That's odd. Do they show that way in ResScan? ResScan shows "data skew" sometimes but it usually just sets the flag to the right by a consistant amount, sometime a minute. I've never seen one marked short. I wonder if that's sleephead.

I don't have ResScan, maybe I should get it. You see the markers align with the sensing Hz signal ending in the 2nd chart, so it's probably not SleepyHead. What I think it is ... it's just that there's a wee bit of respiration, see the tick marks in the upper chart, just enough to trip the algorithm in the S9 to think it ended, but then in the same way, starts counting again (see the two 11s durations). I think during that time I'm right at its decision boundary. It's just me, livin' in the edge

I would give it a look in ResScan out of curiosity. The newest version is in uncle_bobs signature. I'm not sure what pressure range you are using. Have you considered trying straight CPAP. It works much better for me and I don't need as much pressure to keep the apneas at bay. I think sometimes we unconsciously fight the machine.

6-14 cm H2O. Works pretty well for me. I was 5-14 but last night bumped up the bottom to 6 as 5 was for me to get used to the machine ("Kiddie Ride" I called it to the Resp. Therapist ). Now that I am acclimated to it, 5 is too wimpy and I see in my charts I rarely go back down to that, so I put on my big boy pants and went to 6-14

I like my auto settings and I have done well with them, until these last two nights with just a wee bit of OA storms and, coincidentally, those are two nights that I had 1.5 oz of brandy right at sleepy time.

I just went back through my SleepyHead reports when I was trying a ResMed VPAP. Everyone of the markers were at the end of an obvious event. I looked at data over a 2 week period. You maybe correct with the assumption that the machine thinks the event has ended because of a slight increase in respiration.

Now my Respironics flagged events...the flag is almost always in the middle.

GACK! It's contagious !! LOL

OOH! I want one of these. I don't suppose it would be easy to use with my Mirage Quattro FFM though.

Max uses a quatro, I think Jay does too.

OK, a better night's sleep. Another Zeo score (ZQ) of 78, about what someone 20 years younger than me would normally get. I didn't have the string of events, tho I self medicated identically this 3rd night.

I would say the Zeo's classification of sleep stage is quite often off by one level. I was awake, got up and "did some tinkle business" at the red line, should have been a clear "Wake", but it didn't classify it as such, maybe because it took less than 2.5 minutes (less than 1/2 the bin size in the chart). I woke up at least 3 times, and they missed all of them, but then again those wakes might have been less than 2.5 minutes so it would not show in this 5 minute data. I'll look at the 30 second, it should show there, including dropped signal, as I saw the Zeo clock showing no patient reading for a while as I moved around. Some of the "Light Sleep" is probably really REM, and some Light Sleep is probably Deep, errors by just one sleep stage. I have the luxury of using more data and the human brain, as I can judge sleep stage using Tidal Volume, spO2 and heart rate pretty well, but that data has higher sampling rate displayed.

I think the Zeo is useful, as a guide in the 5 minute bars, but to get more useful information, one needs to look at the higher sampling data.



UPDATE: I looked at the 30 second data and no, the 3+ wakes are not there. I think their classifier could be a wee bit better.

Good to see you didn't have those clusters of OAs last night. Must have been sharks!
