Years ago, my father was diagnosed with severe OSA. My wife went to the doctor with me for a checkup and she mentioned I have some erratic behavior when I sleep and I had a sleep study. I also had severe OSA. I am not a new user of CPAP, but I never shared this story. I have very vivid dreaming. Since the CPAP therapy, my dreams are sometimes so crazy. Recently joining the Apnea Board and getting the correct software to access my data (my current therapist could care less when I call asking for help) I noticed that my ResMed S9 Autoset is detecting that I have CSA now for up to 20 seconds, multiple times a night. The obstructive apneas still happen, but by far the CSAs are predominant. So I pose some questions: Do others experience this? Is this kind of change signal a health issue that I should get to the doctor? Could the CSAs cause this weird dreaming? Huh

RE: [split] Central Events
Hi Chucks. I'm splitting this into a separate thread so others are more likely to see it and respond to it.

So your AHI is dominated by your CA index. Can you tell us what numbers you're getting? Like for example if you take the last week's worth of data what is your AHI and your CA index? Also, what is your pressure (average pressure, 95th percentile, etc.)?

It could be that when the pressure is too high it induces the central apneas. Perhaps lowering the pressure will help. Have you talked to a doctor about this?

Hi Chucks, welcome to the forum!

How many months or years have you been using CPAP/APAP? (Often the CAI will improve over the first several months of treatment.)

Also, it is fairly common for us to have a few central apneas or hypopneas which occur before we are fully asleep. The machine does't know you were not asleep, so it will mistakenly include these central events when it calculates the CAI. So we will need to look at the data (time record) and discount any central apneas which occur while we are falling asleep.

The respiration tech at my doctor's office recently told me that most US insurance companies will not pay to upgrade a patient's machine (from a standard CPAP/APAP machine, to a machine which also treats central apnea) unless the CAI (Central Apnea Index, average number of central apneas per hour) is 16 or higher, or unless the central apneas are sometimes very long, like a minute or so.

However, I think Medicare guidelines only require the CAI to be at least 5 and predominant (CAI larger than Obstructive Apnea Index).

In any case, if the number of centrals is not averaging at least 5 per hour, as far as I know the US medical insurance industry would not regard it as serious enough to need to be reduced.

Looking forward to your reply to Sleepster about your CAI, AHI, average/95%/Max pressure, etc.

Take care,
--- Vaughn

The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
