Resmed S9 Daily Data Incorrect

You can turn off the pie chart in Preferences/Appearance tab and that will let the AHI orange graph show up.
Doesn't matter right now though. I mention it for future reference. I don't need anything else right now from this report.

You don't take any meds that might suppress your respiration do you? Pain meds?

You likely need more nights (now that leaks are better managed) to see if the pattern stays the same with the centrals and if it does I predict a different machine in your future.

Did you have a sleep study WITHOUT a cpap machine that also showed the large number of centrals or did the centrals just show up at the titration sleep study where they put you on the machine?

I am on no pain meds. The study was done only with a cpap. My next review is in January I believe.

So the original study was a home study? Do you happen to have those results? Just curious.
Trying to figure out if you had centrals numerous enough to be a problem even without a cpap machine or did the cpap pressure cause the centrals.
If it is the cpap pressure causing the centrals there might be some wiggle room to play with the settings to see if the centrals will reduce. Though I assume that if the sleep tech said he couldn't find suitable pressures then the chances are slim.
If the centrals were present during the home study without cpap..no amount of tweaking the pressures can likely make much of a difference.

It is odd that the worst of the centrals is in that one big block though....but need more nights with leaks managed to see if that pattern hold or if it was a fluke. At this point I wouldn't change anything and just use the machine and keep working on the leaks and see what pattern future reports show. For sure no increasing the pressures.

The study was done at hospital center not at home and I don't have the results. The study was requested do to irregular heart rate. That was determined to be from a long existence of untreated apnea per my cardiologist.

I will watch the numbers and repost a log in a few days.

Okay...did you have a sleep study at the hospital where you slept part of the night without the mask and machine and then they woke you up an put the mask on? We refer to this type of sleep study as a "split night study"...first half of the night without cpap and second half with cpap.

People don't just normally go in and start right out with the cpap machine...there usually is a diagnostic study without cpap machine first. This sleep study with no mask and no machine...that is the one I am wondering about the presence of centrals during it.

With your history of cardiac issues...be sure to keep that appointment in January.

You are correct the first night was without and the follow up night was with CPAP. Nothing was mentioned about Central until the night with the CPAP machine, so not sure if it was present without.

When you get a chance see if you can get your hands on the reports for those 2 sleep studies. If centrals were present on the non cpap night it will definitely be mentioned.

Pugsy, last night 6.1 hours of sleep and AHI 2.6. I had not been using the machine for about 10 days to two weeks due to a bad congestive cold. Looking back at the logs previous to that my AHI was not high like is has been the last couple of days. Ranging from 1.6 to 6.8 but most in the two's. I don't know if the lack of use for a couple of weeks would effect it like that but just a thought.

Sometimes we all can have really whacko nights.
If AHI was only 2.6 last night with 6 hours of decent sleep (I assume you slept) then even if they were all centrals it's unlikely that you had a large number of them.
If your AHI will stay below 5.0 with this machine and bad nights with huge central clusters are rare then this machine may very well work out for you.

How was the leak rate last night? Remember....leak rate must be within acceptable limits for the data you see to be valid and accurate.

I have no idea if not using the machine for the previous 2 weeks may or may not have contributed to anything.

From the charts how do you tell if they are Central or Obstructive Apnea's? Sorry if this is a question that has been asked a lot but I could not find the answer within the SleepyHead documentation and this is new to me.

Your machine will flag centrals...ResMed and ResScan calls them centrals but Sleepyhead uses the term "Clear Airway" instead of central.
So Clear airway events in Sleepyhead are centrals.
Originally SleepyHead was written for Respironics machines and Respironics elected to use the term "clear airway" for what are essentially centrals (open airway cessation of breathing). So it was left as "Clear Airway".

OK, were is it flagged on the graphs or is it flagged somewhere else?

Clear Airway...CA....shown on the Events graph top right and on the details tab where the AHI is broken down into categories.
From your first example in the first page of this thread....I circled the CAs/Clear Airway/Centrals in red.
