It's my first post to this forum however I've been on and off CPAP machines for a few decades now. Having rejoined the plastic lung crowd, after getting help with a local hospital's sleep lab, I'm not getting the results I was hoping for. There are a number of considerations here and I'm hoping someone can advise/suggest something I could try.
To put the subject heading in context, said sleep labs gave me a CPAP machine to trial as I adjusted back into using CPAP. I tried a few masks but settled on the Phillips Dreamwear mask, which I have been using with the hospital-loaned machine and my recently purchased one. Personally I have mild OSA, which the lab determined I could treat using a fixed pressure CPAP set to 7. The results that came from the Resmed 10 CPAP (set to fixed pressure) showed AHI values consistently below 1. Lately with the (recently purchased) Fisher & Paykel Icon Premo I am getting AHI readings between 3 and 5. Although this is still acceptable I am wondering if the Icon is interpreting things differently or could the machine be performing 'less' than the Resmed 10 unit?
If the AHI readings were slightly higher the CPAP treatment would be pointless as this is what I was getting without treatment. Some may ask why I'd bother with CPAP with such a mild case of OSA. To answer, my doctor has recently diagnosed me with Chronic Fatigue Syndrome, and has suggested OSA may only be part
of the problem, with other causes yet unknown.
As a side note, previously I had a weird reaction using the (previously purchased) Icon Premo, which I sold shortly after due to not finding a resolution to this reaction and receiving no proper medical assistance. After using it for the first night I experienced vertigo, to a point where I had to 'compose myself' before getting out of bed, ie dizzy to the point of almost throwing up. Any exertion during that day lead to a short dizzy spell where I'd need to grab hold of something as I felt I was going to drop. This time around (starting on the loaned Resmed 10) I had a brief recurrence of this vertigo problem but haven't experienced this issue for some time now.
Basically I'd need to know if this higher AHI reading is a 'non issue' or is this unit no good. I have heard good things about the F&P Icon Premo, and both the Resmed and Icon Premo were using a fixed pressure of 7 so it make it hard to believe it's due to the machine, ie if I was still tired after using an autoset I could consider it (possibly) an autoset algorithm issue, but fixed pressure is fixed pressure.
Hopefully I didn't rattle on too much. It would be great to hear suggestions or get advice as my next sleep lab appointment isn't til February. At the moment I'm having to prop myself up on Modafinil, which I'd rather not. This stuff has a 12 hr half life.
