Interpretation please? - zzzZorro - 02-11-2018
There are three disturbance 'burbles' in the FlowRate chart. 01:54:04, 01:56:04 and 01:57:23
Do these indicate position change or what would you guess them to be? Also trying to decide IF these may be induced by algorithm pressure increase.
If you have any idea please explain 'why' as I am trying to learn.
Thanks

If by "burbles" you mean higher amplitude flow rates, they are a little difficult to analyze in isolation on the graph. They are higher rates of flow, and may be due to body position changes, inspiratory effort or arousal. They are reflected in minute volume and longer inspiratory time. Most of your night looks fairly decent except for that rough patch at 00:20 to 00:40.

'Burbles', a disturbance in the graph pattern- like at 01:54 where the consistent pattern goes nutz- then immediately breaks into a CA.
..Does the CA at 01:55, that happens during a pressure elevation, and the two OA following appear to be pressure induced (or happening because of machine algorithm behavior)?
My best results have been mostly in CPAP mode fixed about 13 to 14 cm and no EPR. (around AHI-5) This was a Vauto experiment.
THANKS SR for the input.

If the VAuto was a CPAP your settings on the VAuto would be 15-24, EPR =2.
The settings on a BiPAP/BiLevel are for the EPAP and on the CPAP they are for IPAP.
Change your settings on the VAuto to your 11-22 PS of 2 to "match" your CPAP
To take advantage of the Auto mode I'd suggest settings of 10-22 (Epap) PS of 2 (Note: most start with PS or 4 on BiPAP/BiLevel)
Vauto Epap + PS = CPAP Ipap = Vauto Ipap
CPAP Ipap - EPR = Vauto EPAP = CPAP Epap

zzzZorro, your airway destabilizes unpredictably, and steady pressure with low or no pressure support has consistently proven a winner. If I knew how to fix "burbles" I'd probably not feel so bad about last week's stock market effect on my retirement.

Perhaps 'burbles' was not a good word but you got the idea.. Steady pressure and no PS appears to be the best 'fix' for my personal abnormalities. I have found that auto and S-modes will work better than they used to but still not as good as fixed pressure. I think I have the ability to drive the algorithms to insanity. Maybe time with the machine improves things!?
Fred; I'll keep your suggestion in mind for the next time I venture off the range.
Thanks

I'm sure you will continue to confound the best technology as well as you have perplexed the best minds on this forum. It seems you have tuned into your needs and responses and now command the machines to do your bidding. Welcome to the Matrix.

chart 1, all of them follow a rise in flow/tv,
The last one was the only only one that had a real drop in MV and that also followed a large rise. It looks like you are just breathing between oa or waiting for the co2 to catch up. I wouldn't give any of them a second though. I think your o2 meter will agree. You have a freaky pattern that doesn't respond to pressure like normal apnea. I don't know how much is just that the machines aren't clever enough, to see what is going on. A doctor that wants to chase it down and a good lab tech will be the answer.
