Central or Obstructive: Does it matter?

Hi all,
Newly diagnosed guy here. And I have a few questions. In the titration report, it says "...OSA with an RDI of 15.1 events per hour..." Now when I look at the summary, it shows 14 central apneas, and zero obstructive/mixed. So my big questions is do I have OSA or CSA? I'm getting a CPAP regardless, but this sort of confuses me. Thanks in advance.


The list below is what I think I want.

I think you need to have your doctor explain the sleep study results to you.
They came up with that RDI of 14 so that means an average of 14 something or others an hour and if they say 0 obstructives...something else was added in to get the RDI and OSA diagnosis.
14 centrals over the entire night or per hour?..sounds like over the whole night and if over the whole night with 5 or 6 hours then it wouldn't be nearly as big of a deal as per hour.

Also, check for hypopneas.

Yes, it does matter, if those central apneas are deemed significant. Some are, some aren't. Some questions are if you also had apneas on the diagnostic study or were they maybe a response to pressure. Some people have complex apnea which has a central component. Other times the pressure needed to effectively treat obstructive events triggers centrals. Sometimes central apnea is seen with certain health conditions. Too much is unanswered, and those answers could make a difference in what machine you need to have to meet your needs. I certainly wouldn't accept a machine until I had all my questions satisfactorily answered. Let's hope your centrals were the garden variety type and insignificant.
