Sleepyrider...
Saturday night without fever, I had an exemplary preparation after a day dragging myself through it (after the nights before), having recovered somewhat with the 20min rest within the appropriate hours (1-3pm I'm told). No alcohol with blood thinning and a nice meal with the company of a loving partner. I'll admit, 8.37pm is a tad early to be putting head on the pillow, but...I am getting older (74 in Nov), and well, I was ready for sleep.
That all said, on arousing after 3hrs 06min I was pleasantly surprised at the duration, if not the AHI number. However, again no CAs, OSAs or CSRs as in the past...surely positives:
Over to you this first session, with another post to follow.
Cheers...poppypete...and again,

2nd session of 1hr 54min...graph info attached.
Cheers...poppypete
Ps...for the second night now, the oximetry readings reflect less volatility in both heart rate and SpO2%...and I feel better too.
RE: afib and sleep apnea - jaswilliams - 06-09-2018
It looks like more pressure support and max iPap will be required to solve the hypopnea as the ASV is being choaked by your current settings but sleep duration and comfort is also important at this point
I am typing on my phone so will be brief

Not totally understanding myself your evaluation...and what to do about it, and in the absence of further sage advice from Sleeprider, I maintained settings for another night...for apparently a similar result (graphs attached, of relevant 'sleep/nighttime' rest/slumber).
When you have some more time, could you elaborate please?
Thanks...poppypete

I'm attaching a graph showing the highest unclassified apnea in this first session last night, and I will attempt to further add a snapshot from my Windows10 of the MedView download (from my ChoiceMMed MD300W314 oximeter...of the same period of that event's happening (you'll recall my thread/post from the Software Forum, explaining my current difficulty with syncing these two programs).
Anyway, let's hope this shows how relevant is my Afib effects on my apnea event results...and why patience is the name of my game at present.

Success???
RE: afib and sleep apnea - Sleeprider - 06-10-2018
I agree with the comment you need more PS max to deal with these events. We don't know if the UA events are obstructive or central. I thought with your central apnea that your needs would mostly be with low EPAP pressure and moderate pressure support, but that theory is fading fast. I'm going to start with the assumption the events we are seeing are central and rely on pressure support to resolve them, but just in case, I think we will allow a bit more range in the EPAP. You had fewer of these UA events in your first sessions when EPAP was allowed to go higher, and I'd really like to see the UA events controlled since they seem to be pretty long. I'm struggling to understand what is going on as we usually see pretty quick results.
A quick favor on graphs; please turn off the pie chart in File/Preferences/Appearance. We may want to zoom in on the flow rate at some point to see what is really going on with these apnea. My next best guess on settings is below. Do you have a titration study scheduled?
EPAP min 5.0
EPAP max 10.0
PS min 1.0
PS max 15.0

Hi Poppypete,
I'm on a laptop now so can type much easier....
There are two things going on in your numbers, you are suffering Hypopneas & UA's, to treat the Hypopneas the EPAP needs to be raised this may also reduce the UA's but if you look at the pressure graph you will see the tops of the graph are flat and the pressure reached is 17 this is the max of IPAP + PS the ASV will go as high as 26 (I think if given leeway to do so) the flat tops mean the pressure was limited by your settings.
Follow Sleepriders advice on pressures and we will check the numbers tomorrow, the numbers shown on the Oximeter look good even though you cant sync them.

Sleeprider...
Thanks again for this consideration of my needs, and in answer to your question about a titration study, simply no.
I see my GP this morning about the Warfarin dosage for the next month, and I next see a specialist on July 5, that being the sleep 'expert'. I guess he'd be now open to my requesting a titration study before that date, which could be organised if you think this is the quickest path to resolution of this complex web I've weaved...as I've lost confidence in the relevance of the home study's data being now relevant at this point of time/progress.
Pie chart is now off.
Flow rate zoom: I've now done that as an experiment...on the UA referred to in my reply to jaswilliams.
I'll try those new settings today/tonight.
Once again, thanks.
Cheers...poppypete
Ps...I'm feeling better by the passing of each day and night, by looking also after other areas of import [no alcohol; diet; and outdoor strolls and bike riding to the local beach (winter here, so swims are off the menu.)]

re: "My next best guess on settings is below."
EPAP min 5.0
EPAP max 10.0
PS min 1.0
PS max 15.0
Graph result with these settings attached.
On the oximetry readings, steady SpO2 >92% min from 22.30ish until 4 hours later.
I'd suggest a good night's result for me!!!
Thanks...poppypete
