Re: Flow rate shape question
Actually I think you are trying to see things with the data available that it really wasn't ever designed to show. Assuming facts not in evidence. Trying to see stuff that isn't easily seen and was never expected to be seen with the data the machine gathers. Now just because we can't see things doe...

Re: Flow rate shape question
Ok today I had a good sleep, like I normally would with the CPAP. Not sure what was causing the poor sleep these past days. I tried changing which side I sleep on, maybe that had some effect. Still can see quite a number of mini arousals in my sleep, and I think if I can figure what's causing them I...

Re: Flow rate shape question
Thanks very much for the reply. There are a few things in my mind right now about how I can proceed. The first would be to get an in lab sleep study done which would let me know my AHI and hopefully my RDI scores as well as my oxygen levels. I think that would be a good place to start to rule out th...

Re: Flow rate shape question
Yeah, that makes sense. I have tried an EPR of 3 but that seems to make no difference. Not sure what to do now. I thought that the breaths preceding the arousals look flow limited, so perhaps it is the flow limitation that is causing the arousals. But if increasing the pressure doesn't help, does it...

Re: Flow rate shape question
From my Resmed data. I know the machine hasn't marked much flow limitation, but I wonder if, looking at the individual flow rate curves, there is flow limitation evident that might be the reason for my unrefreshing sleep. Do you suggest that I try increasing my minimum pressure gradually to see if t...

Re: Flow rate shape question
Hello, I just wanted to share some more images which might be relevant. What's strange is that my sleep wasn't too bad with the CPAP until about a week ago. I am now regularly waking up very fatigued. There could be some other factors at play but I am not sure. I am not taking any medications. I am ...

Re: Flow rate shape question
Thanks for the detailed reply! I really appreciate it! Yes, I think I will try increasing the pressures gradually to see what works for me. I have tried a baseline pressure of 9 for about a week or so (and even 10 for a couple of days) and I didn't experience much improvement, so now I'm jumping dir...

Re: Flow rate shape question
OSCAR doesn't do any flagging. OSCAR only reports what the machine reports, records, flags. Those are very minor changes in flow rate and instead of being the cause of an arousal I think most are a symptom of an arousal. At any rate....give reducing EPR a try. When you reduce EPR you effectively in...

Re: Flow rate shape question
Thanks for the reply! Yes I think I do need to work on getting uninterrupted sleep. The gap that you point out - I think I naturally woke up at 22:30 (the timing is wrong by the way, I haven't fixed it yet - it was actually about 7 or 8 AM). I then had to do my morning prayers and then I spent some ...

Re: Flow rate shape question
Right, thanks. I imagine that they could still disturb your sleep though, especially if they are borderline events. I've been having very poor sleep since the past four to five days and this is only thing out of the ordinary that I could pinpoint in my OSCAR data. I do have quite a number of these t...

Re: Flow rate shape question
A thought just occurred to me - could it have something to do with my EPR settings? I've noticed that my sleep was better with the Dreamstation even though I have the same pressure settings on both. On the Dreamstation I had A Flex either on 2 or 3. Perhaps it could be that the EPR of 3 that I have ...

Flow rate shape question
Hello,
I've noticed that I experience a number of the flow rate shape that you can see in the attached screenshots in my sleep. Just wanted to ask - are these events that the machine is not classifying? Or maybe they're arousals?
Thanks
