Is Resmed S9 Autoset mode suitable for central sleep apnea?
#21
Okay so will I just leave my machine set to CPAP mode, what are the advantages of the modes?

I find not so easy answering this question, because everyone is different and respond differently to treatment
CPAP mode deliver one constant pressure all night (except Ramp time), the machine cannot go any lower or higher than set pressure
AutoSet mode deliver one pressure but fluctuate between lower pressure and higher pressure settings
This can be useful for someone who sleeping supine, have one too many, lost or gain weight, etc

I've always used auto mode since starting treatment, but lately, switched to CPAP mode because when on auto mode (AirSense 10 AutoSet), the machine increase pressure up to the maximum and stay there for most of the time as the machine respond aggressively to FL
The FL graph looks neater when on auto mode, but no difference in AHI or sleep quality (maybe slightly better on CPAP mode) ... YMMV

Quote:Why don't you use the software to analyze the type of apnea being scored by your present machine.?

I found some central apnoea events on sleepyhead but my respiratory doctor says that the machine is not very accurate and the only way to correctly diagnose sleep events is in a sleep lab which gathers from multiple data sources.

The doc is flat out wrong. Data in a sleep lab is better per hour, but it's only one night, in a strange bed, with a different CPAP machine, and often is only a few hours of sleep. You might have central apnea at home, and not in the sleep lab, and vice versa. People often have centrals only part of the night.

The data from your CPAP machine is every night, studying the actual therapy you're getting. It might have some technical inaccuracies with events that are on the borderline

However, you should not panic over "Central apnea" in your home sleep data. Everyone has some. What's your AHI? How much of that is central? Also look and see how long the centrals are. If they're 11 seconds long, they're a lot less important than if they're 120 seconds.

There's also what some of us call "Sleep Wake Junk." As you fall asleep or wake up, there are often a lot of apneas and strange breathing events of various types. They're not that important unless they are too severe, too frequent, or last too long.

A: No, different as day and night, as far as ResMed machines concerned
S9 AutoSet is an AutoSet, S9 Escape Auto is an APAP
APAP mode: doesn't treat apnea above 10 treats and doesn't know whether if an apnea is obstructive or central either.

The auto mode on the S9 AutoSet is called AutoSet not APAP.

To everyone other than ResMed, the AutoSet is an APAP or an Auto CPAP. I don't even think ResMed makes the distinction except in some documents tying to market the AutoSet as somehow superior to other Auto CPAP machines.

Summary: YES, the AutoSet is an APAP.

Your data looks good as far as I can tell from these screenshots. In particular, the low AHI. Your flow limit looks good, too.

Zoom in on the individual events and see how long they last.

You could also upload a copy of your SD card to Dropbox.

If you decide to tinker with your pressure, be sure to check your data frequently after the change to look for increased central apnea. Don't increase the maximum pressure much above 10 until you've tested it out a bit.

I doubt an in lab sleep test would show anything significant, if your home data looks that good.

Superior in sense that S9 AutoSet and the newer AirSense 10 AutoSet have enhanced autoset algorthim with central apnea detection
Some PR machines can do that but other brands whether CPAP or APAP cannot

As for central apnea, 1 or 2 events used to freak me out
Went straight to the doctor, he said, i worry too much, he is right, the hair going greyish oldman

I've come to conclusion that, unlike sleep study, machine data useful for trending
For me, I consider good night if I see in the morning, hours on the screen shows anything between 7 and 8 hours ... YMMV

I have run every other medical test imaginable includinf MRI, the only thing that I notice is that my graph logged a large amount of UF2 events around 17 per night, are these awakening events? could the hose itself be waking me up as I turn?

A review of your data shows that your apnea is indeed under control. That doesn't mean it is optimized, but your AHI is low and is clinically treated. Your sleep doctor probably thinks it doesn't get any better than that, and you should just go away and appreciate what he has done for you.

Your S9 does not measure RERA (respiratory event related arousals), but they may be showing up as UF2 events. That is a sleepyhead designation for a machine reported event that is undefined or unknown to the programmer (Jedi-Mark). We don't really know how to address those, but sometimes small changes like variations in EPR, or using Autoset mode can help, or not.

With a fixed pressure of 10, you have essentially no obstructive apnea or hypopnea, and the clear airway events are very low, and could be simply disturbances in sleep. They are not a health concern or indicative of central or complex apnea. There is no harm in experimenting with some alternative machine settings if you want to. Putting the machine into Auto mode and a minimum pressure of 8.0 and maximum pressure of 11.0 might be more comfortable, and should provide comparable effectiveness. Whether this cleans up some of the arousals, we can't say, but it might be worth a shot. You can always resume CPAP at 10 if you don't like the results.
