Understanding Sleep Study Results

I have been on CPAP since August of 2008, but am new to the forum.

Following my sleep study I was sent home for 2 months with a loaner S8 Autoset APAP unit. After review of the loaner I was prescribed S8 Elite II CPAP unit with a pressure of 10. I wanted to get a the original S8 Autoset APAP unit, but was told that the data collected did not support the prescribing that unit under the guidelines here in Canada, I would have gladly paid the difference in the price but this option was not available.

I am currently working to get a better understanding of the results of my sleep study and to learn to analysis the data available from my current CPAP equipment. I have a Card Reader on order but have not yet received it.

From the sleep study results which are shown bellow I have observed the following.

- I had 20 Central Apnea events with 3 of those occuring in REM sleep.
- I had 7 obstructive apnea events with 3 of those occuring in REM sleep.
- I had 261 hypoapnea events with 33 of those occuring in REM sleep.
- This gives a AHI index of 48.2

- I had 221 arousals attributed to respiratory events for 41.3 arousals per hour.

No wonder we all end up tired in the morning.




Is there anything that I am missing in my analysis.

Does the S8 Elite II do anything for central apnea events?

What is the treatment for central apnea events?

Can anyone tell me how the numbers derived from this report may correlate to the results provide by my S8 Elite II?

Since my equipment was prescribed, I have had no feedback from my sleep doctor/lab, and no analysis of data collected.

Any feedback is appreciated.

Thanks

It looks like all of your Central events were during sleep stage shifts, in which case you might not really have problems with central apnea. Did they notice any additional/significant central apnea component during your titration?... or I'm guessing they did an at-home titration, not in the lab. Bi-pap can be used to treat central apnea but in your case you need more data before assuming that you are getting them with CPAP treatment.

Are your leg movements reduced since starting CPAP?

Have they followed up the PVC's (I assume that's "premature ventricular complexes")?

How are you feeling with CPAP? I get the feeling you're not feeling better and are concerned about the CA's ?

Hard to make any additional conclusions without seeing your CPAP data, like current AHI, leaks, etc.
