AHI TREATED OR NOT?
#1
Hi folks,

I've been using a RESMED S9 auto for two years. My AHI ratings are consistently about 18-35. Nothing I do, no settings I set can lower this. Does this mean the machine is treating my apnea? If not what can I do? I've had three sleep studies which claim I can be treated at pressures of 8-12. But setting it there lands me at 20-30 AHI daily. Occasionally I can get a 7-10 rating, but very rarely. I also have a standard Resmed S9 Cpap machine, that when I use this in my travel trailer and am away, it is the same.

How do you know if your apneas recorded on the graph is treated or not when the pressure rises to meet it? I do have clear airway (CA) apneas about 20% of the time too. Any advice is appreciated. Thanks. - fiur

G'day Fiur, welcome to Apnea Board.

The apneas recorded by your machine and reported in ResScan or SleepyHead are not treated. If the machine is treating your apnea properly then your AHI will be low, typically below 5. If you're getting numbers up to 30 then something is very wrong. There could be a lot of reasons for this - the best thing is to see a screen shot from SleepyHead so we can identify any particular problem.

I feel your pain. I've had two sleep studies that show AHI <1 at a pressure of 10, but my Resmed S10 Autoset consistently shows AHI at 7-11 (with just one 4.9). The folks at the sleep lab tell me it isn't the same thing but I don't understand how. Good luck finding a solution!!

Hi fiur. Welcome to the Forum. Post those screen shots from Sleepyhead. We can probably help you with this.

Could be the CAs.
Happened to my wife temporarily . Running consistantly at 1 or below. One morning boom she had ahi of 20.

Turned out to be a new med triggering CAs.
Med gone back to normal.
Point being setting pressures wont fix CAs.
Use sleepyhead abd you can see if it is CAs.

Hello flur
Welcome

Good to see another Coloradan in the forum,Big Grin there are a few of us

My first impression from your starting pressure is it's too low.
You could start bump up the starting pressure in small increments.

The high pressure setting could as be contributing since pressure that is too high can cause CA's, which is exacerbated in people living in Hugh altitude.

Do you live in the valley under 5000 ft or in the mountains?Thinking-about

Without knowing how much of a risk taker you are, or what you insurance/financial situation is, I wouldl also like to recommend you consider a trip over the divide to Denver for a visit with the folks at National Jewish Respiratory Hospital. They are one of the best and oldest respiratory sleep medicine treatment centers in the world.

They have many awards, accolades and bragging rites Rolleyes

Thanks for reply. I Just updated my new machine I received, which is a RESMEd AirCurve 10 VAuto with humidifier. How do I place a screenshot on my post? Any help is appreciated.

Just figured out how to upload screen shot below. Any further help is appreciated. Thanks

My first guess is that you are getting onto your back during those severe Obstructive Apnea periods. To rule out sleeping on your back as the cause you have to make sure that you stay on your side for the night. There are lots of tricks like using pillows or sewing tennis balls into the back of your t-shirt. Many Obstructive Apnea sufferers cannot sleep on their back.

For what it's worth, your minimum pressure of 4.0 is a waste of time. Your machine quickly reaches 15 cm and can't do a thing against your apnea. You need a combination of higher pressure, and getting off your back, or you will have severe apnea even when treated. A soft cervical collar may also be a help.

On the positive side, your leak rae and tidal volumes are very good, so this is a simple case of obstructive apnea. If your insurance is good, and you have a responsive doctor, I would suggest a consultation. Over 15 cm, you might qualify for bilevel therapy.
