[Diagnosis] Sleep study results

[bugo]

I had a sleep study done about a year and a half ago. Here are some of the results:

Sleep efficiency 79.1%
REM latency 330.0 minutes
Arousals 7.4/hour
Obstructive apneas 77
Central apneas 21
Hypoapneas 8
AHI 20.5/hour
RDI 20.5/hour
REM AHI 101.4/hour
Supine AHI 10.2/hour
Mean wake SpO2 93%
Minimum SpO2 78%


Are any of these severely abnormal? I understand the REM latency is high and the REM AHI is extremely high. What about the others?

I have been using a CPAP machine for a little over a year and it helps but is not a cure. Should I worry about the 21 central apneas?

With an AHI of 20 per hour, you were diagnosed were Moderate sleep apnea. That was over year ago.

Normal: AHI<5
Mild sleep apnea: 5≤AHI<15
Moderate sleep apnea: 15≤AHI<30
Severe sleep apnea: AHI≥30

If you have been using your Cpap for the past year, then what matters now is your current AHI and how you feel. There is no cure for sleep apnea, but with the correct therapy settings, you should be able to see an AHI under 5, possibly lower.

Are you still experiencing a high number of Clear Airways?  

You only need one more post, then you can post a #SleepyHead screenshot of the daily page here.

We would be happy to look at your data and advise if that is what you would like. Also, you profile is lacking information.

bugo, the fact you had a high proportion of CA events, and your supine AHI is low, while REM AHI is extremely high, may suggest you have a complex apena problem. Hopefully you will be provided a titration study that will evaluate the effectiveness of CPAP. I would guess your odds of getting good results on CPAP are about 50/50, and you may need a different therapy approach. I would prefer to see someone with these results get a titration test than to simply be issued an Auto CPAP machine for self-titration. It is possible that central apnea will continue to be an issue with CPAP. If the machine you have been using produces data, we can probably do better than guess. If CPAP does not work to reduce events to an acceptable level, there are bilevel machines that can help you to breath during central apneas or hypopnea.
