Central Hypopneas suddenly! - Kingsway - 11-19-2023
I recetly went back to my old Airsense 10 for a couple of weeks, in order to be able to use its humidifier - but aslo to be able to use OSCAR to have a look at my progress.
This was very useful as I could narrow down my settings, and get some of the lowest AHI figures I'd ever seen (as low as 0.3)
I've now gone back to my official machine (Sefam S.Box - as supplied by my local clinic - with no humidifier other than my DIY one)
Using the Airsense and Oscar - I rarely see any CA events reported :

However, when I go back to the S.Box and the Sefam Analyze software (using similar settings) , I can get quite a few groups of Central Hypopneas

I'm wondering if one machine/ or software is doing a better job than the other...?
Do I need to worry about it??

Why would you decide to use the inferior device with no humidification and less customization?

Fair question! -
Because I am being treated - at no cost (machines, masks etc etc etc) - by my NHS Health Trust Clinic. They monitor my compliance using the Sefam Machine that they supplied. Non compliance could jeapodise my Licence to Drive... BTW I will be getting a humidifier when they come into stock - but its been more than two months...)
I may just try to ask the Clinic at some point - but they seem to monitor hours used and AHI + Sleepiness scale only.... It's possble my waveforms might be reviewed by a doctor at some point - but I wouldnt like to count on it! On my last visit, the nurse didn't appear to be aware that I had not used the SEFAM machine at all for a period of four weeks in the previous six months.
They also said that at my annual review - which will be done over the phone - they will want want hours-used, plus 90% pressure reading, and average AHI !
I'm hoping one of the knowledgible folk hereabouts - can advise if they think I need to take it further with the CA's

Both examples are arousals preceding the event and and the "centrals" are you responding to the arousal.
Neither chart provides any indication of why you had the arousal.

Agree with Gideon. I see no suggestion this is a central event other than the way it is flagged on the Resmed. There is a large breath and two smaller breaths ahead of the pause. I think this is a shift in position. The Sefam shows periodic breathing that may be central or a normal response to some CO2 balance issues.
