[Health] Interpreting sleep study results, EERS enhanced expiratory rebreathing space

[JoeyWallaby]

I feel terrible today. Where charts end is where I took the mask off and spelt for multiple hours after that. I don't know why AHI is so high and leakage as well... no alcohol, taped mouth, mask on pretty secure, EERS on. I'm thinking of increasing min pressure to 10 and turning off EPR.

Can anybody look at data for this night and tell me if there is anything interesting? https://www.mediafire.com/file/th5nm2qmw...e.zip/file (password apneaboard)

Hi, Joey
no wonder reasons why your are feeling poorly. Keep on going with a very compromised respiration and an untreated UARS (see attached).
Hope, you and our fellows here, would agree: with all respect and consideration for everybody,  as i have already mentioned earlier; best alternative for you would be moving the soonest as you can to BPAP.
good luck

Why would you turn off the EPR? That doesn't make any sense to me.

I think you need to resolve the leaks first.

Thank you very much for the cool chart. How are you making these?
Do you think trying a higher EPR value would be beneficial, considering the CAs appear to be controlled by using EERS?

I'll try putting my mask (N20 Classic) on tighter tonight.

hi, Joey,
Thank you very much for the cool chart. How are you making these?....just gathering from your post and bring to excel, updating daily...
Do you think trying a higher EPR value would be beneficial,....No, I don't think so. Although it slightly better with EPR 3, however far from enough..... considering the CAs......as I have mentioned earlier, it looks to me your CA's would be all fake events at sleep/arousal/awakenings transitions.... appear to be controlled by using EERS?....don't know much about this.

EPR 3 far from enough. Do you think a PS of more like 5-6 is required to treat UARS?

...It would depend on your normal RR, analyses, and so on......PS could be just 3.6, for instance, yet changing everything. You know, each person has his "good enough", no beat below or above, so to say....it has to be fine-tuned.

The last night of charts shows persistent flow limitations and indicate the need for more pressure support / EPR. It appears that EPR was turned down to 1 which is the opposite of where this needs to go. Restore EPR to the highest setting, and work on the leaks.

[JoeyWallaby]

EPR 3, min pressure 10 with EERS. Put mask on more securely and taped mouth, reduced leaks a lot. I feel good today.

Are these CAs, "real" CAs?

[Gideon]

Yes, these are real Treatment-emergent central apneas. If these show consistently you could increase the length of the re-breathe tube and thus reduce the CA events.
There would be a balance between the rebreathe volume/length and the amount of PS or EPR is used.
