Need help and advice on Quality of sleep and AHI

[Sleeprider]

Hi Ravik. The first link in my signature describes the best organization for posting charts. Mostly it would help if you put Pressure in place of AHI on your screenshot. We can tell your pressure of 5.5 to 10 is letting a number of obstructive events and hypopnea through. The best way to resolve that is simply to increase minimum pressure. I recommend you increase it to 6.5 cm. The Philips Auto CPAP is a good machine, but you have to give it a kick-start at low pressure or it just doesn't get into the sweet zone. Your treated AHI is under 4 and and you have 7:48 hours of therapy; that's a pretty good start. Is everything else comfortable?

if you are feeling well rested, I would say I don't think your numbers are bad at all, and to keep it up. There may be small adjustments you can try, but your treatment appears to be effective.

I noticed that most of the events are hypopnea, not breathing halts. Also, noted that the FL flow limitation numbers are good.

I am a mouth breather, but do shift to nose breathing a lot once asleep, and the F10 has been my mask from the start. An open mouth/month will not affect the treatment much as long as you have a mouth and nose combined mask.

Good luck.

Thanks OpalRose,

I am uploading more daily images. I changed min pressure to 5.5 last week but that did not help much, I changed it back to 5copule of days back. I am not sure what is the issue. If I increase min pressure to 5.5 and up the central apnea events go up.

Thanks,
Kewal

Wow!! I have so many helpful responses already, thank you all for your timely help and comments.

Every graph shows the same thing. Your pressure never changes. The saw-tooth pattern is built into the algorithm of Philips where it tests a higher pressure. You could make your minimum and maximum pressure the same, and that pattern will go away. As I said, I don't see where a pressure of 6.0 would hurt, but your results are very good.

Hello QAL,

I do not feel well rested for about last 5 weeks, I right now have headache from last night sleep episodes. My daughter was complaining (from her room) that I was snoring loudly but the machine does not register any snores too.

If you look at the first screenshot I tried ResMed F10 between March 8 and 13. It did not work for me. I have also added overview char to give some idea of events. Purple in AHI bar is central apnea, blue is hypo-apnea.

ok, thanks. wow. snoring kind of implies you are obstructed. can you take a 15 minute snapshot showing a cluster of H events, and another including CA event(s)? That should illustrate some of the activity characteristics.

sorry you are not sleeping best.

Interesting long-term graphs, and I see that period in March where you tried higher minimum pressure resulting in higher CA events. The sensitivity to higher pressure suggests there may be an element of complex apnea that is not expressed at your current pressure. If so, then setting minimum and maximum pressure the same or using CPAP mode may be advantageous if you try a slightly higher pressure (6.0-6.5) again. Both the snoring and hypopnea show you need a higher minimum pressure, and we may be able to avoid the CA events using CPAP pressure so the minimum is the only pressure you experience. Your events are okay, so residual fatigue is probably related to the fragmented therapy sessions. Looks like a lot of disruptions.
