Almost at my 1 year mark - Centrals Question
#1
I am almost at my 1 year mark and am still having poor sleep and daytime fatigue. I will be going back to my sleep doctor and wanted to gather some thoughts and questions to bring up. I am still puzzling over my centrals which, at the time they said, did not matter and would go away.

1. My averages according to Sleepy Head

1 yr  AHI = 4.26, OA = 1.16, Hypo = .50, Central = 2.59. Avg Leak Rate = .51

6 months AHI = 4.21,  OA = 1.21, Hypo = .56, Central = 2.43, Avg Leak Rate = 1.75

30 days AHI = 3.72,  OA = .84, Hypo = .47, Central = 2.39, Avg Leak Rate = 1.12


I am using a biPap Resmed Aircurve V10 Auto and Swift FX Nano For her
EPA 4
IPAP: 9.4
PS = 4
VpapAuto

We had to lower the pressure so much because of severe aeropaghia and ear pain.

What was your apnea index during your sleep study?

I wouldn't worry about the centrals -- at least by the numbers.

I would question the benefit of a bilevel auto machine at such low pressure.

If you are still tired after a year, are there other medical conditions that come into the picture?

If the CI is staying below 5, there is nothing to worry about. It happens with almost all of us. If it ever starts to get above 5 and stay there, then there is reason for concern.

Within the bounds of your tolerance for comfort due to aerophagia, there are some basic principles you can apply. OA is generally better controlled through higher EPAP. CA can sometimes be reduced by lowering pressure support. With these principles in mind, very small increases in EPAP with small decreases in IPAP may bring you closer to a quiet, refreshing sleep.
