Is an ahi of 5 to 10 sufficient to determine my sleep qualit

[djn1]

HI friends

I had to set up my autopap machine myself- my doctor was not available. I set temperature to 72 , humidity to 6 (highest) on my Resmed S9 autoset, cuz a lower setting was drying my passage. on average I use the machine for 4 hours every night, sometimes 7 hours . My ahi ranges from 5 to 10 , although sometimes I remove my mask without knowing , during sleep.


Is an ahi of 5 to 10 sufficient to determine my sleep quality. I have used the machine for 2 months now; is there anything else to look for?
Thanks

No, and I'm not sure if you understand what the machines measure and how they function.
I'm unclear as to what "yardstick" you're trying to use to determine "sleep quality".

You haven't mentioned what your pressure settings are.
If you've set it at the wide open range of 4 - 20 cm., your minimum pressure probably isn't high enough to prevent many events......especially if you're the type of person who doesn't snore much or have many Flow Limitations. The FLs and the Snores are what drive up pressures. You're probably having events before the machine can respond.......if it will even try.

Are you monitoring your therapy with software or are you just looking at the numbers in the LCD?

Too much humid can contribute to congestion, which can in turn contribute to a claustrophobic feeling which can cause a person to remove their mask during the night. Higher humidifier settings can also contribute to a higher AHI.

My Resmed S9 has an info button. When pressed after I awake in the am, its says sleep quality : AHI 7 ; implying that the ahi measure relates to sleep quality. Its on autoset so the pressure goes anywhere between 4 and 20.Once I saw the pressure reach 14.It has climate control (for temperature and humidity) , which I think it regulates automatically. I dont have software to monitor this . Does anyone have a recommnedation that works on windows and what do I need to look out for? MY ahi READING EVERY MORNING IS BETWEEN 5 AND 10 sO SHOULD i BE HAPPY OR CONCERNED ABOUT THAT. thank you

Below 5 is considered good, but many people need below 2 to feel better.

Pressure is set wide open, so a higher minimum pressure will probably reduce your ahi. But you need to look at the full data to see what your pressure is doing.

The fact that you use your machine for only half the night means that you are sleeping like crap for that other half.

The Sleep Quality screen shows the bare minimum info.
If you hold both silver buttons down for a few seconds (until the screen flickers and the wrench appears),
you can view the Sleep Report screen, which shows several more numbers, either for the most recent night,
or for averages of 7 days, 14 days, 1 month, etc.

There's so much more to good sleep quality than AHI...I sort of wish that ResMed hadn't stuck "sleep quality" on those numbers.

Get the software and let's see what's going on...need to know the event category breakdown as well as the overall AHI.
Your AHI sounds like it is probably too high but don't know what to do about it till we see some reports. Need to see which parts are too high.

Even if the AHI is 0.0....if you wake up often or don't get 7 to 8 hours of good solid sleep....you aren't going feel so great.
There's so much more to feeling better than just the AHI.

And if you sleep with your mouth open, you're probably losing Cpap air and will feel dried out in the a.m. If you can use a chin strap, tape or full face mask to see if things improve, you'll very likely not need your humidifier anything like as high as it is (unless you're in Arizona or Colorado!).

my SLEEP REPORT (onthe lcd screen ) FOR THE LAST 30 DAYS SHOWS usage of 5.7 hours, and pressure of 11.2, leak of 10L/min . thanks

[Pugsy]

What is the event category breakdown for your AHI?
Centrals
Hyponeas
Obstructive Apneas

[djn1]

hi, This is a breakdown of my ahi BEFORE getting the cpap (from sleep study).

UAI =0
OSI=52
CAI=3
MAI=1
HYPOPNEA INDEX 10
TOTAL 66 (AHI)


Oxygen DI =50

sTARTED CPAP ON 10 aUGUST 2014.With machine my new ahi averages between 5 and 10. thanks

[Julie]

Pugsy was asking about your numbers ON Cpap... how many obstructive events, how many hypopneas, centrals, etc. What your machine is telling you now is important to help understand whether your treatment is working. And why only 4 hrs/night? You're not getting treated the rest of the night which kind of spoils the other 4 hrs.

[Pugsy]

Julie's correct....I was wondering the event category breakdown NOW while using the mask and machine...what is the event category composition of that 5 to 10 AHI that you are worried about?

What leak rate are you seeing?

You really need to use the software and get more detailed reports and post them here so we can get a better idea what is going on.

If you already have the software up and running read this that explains how to post images and also shows some examples.

Are you using the ramp feature?

What are your pressure settings? It appears to be APAP mode with a minimum of 6 but it's maxing out at around 15 and I can't tell if you are using EPR or not. Looks sort of like it.

Can you get me a copy of last night...in the daily detailed reports showing these graphs.
On the left side...the AHI bar graph..(turn off the Pie chart in Preferences so that the upper statistics will show
On the right side...these graphs
Events
Flow rate
Pressure
Leak
and Flow limitation graph
turn off the AHI and mask pressure graphs as they aren't needed and keep the leak graph from coming into view.

Your AHI last night was 3.90
and broken down into categories
OA...2.92
Hyponea...0.16
Clear airway (central)...0.65

Last night the AHI was in acceptable ranges.
You did seem to spend some time in large leak territory but not a horribly prolonged length of time. Can't tell from just these statistics how far you went which might possibly be far enough to maybe miss some events but 5% of the night is unlikely to be a major statistical problem.

The bulk of your AHI seems to be OA...depending on what the pressure line shows and the flow limitation graph...and what your current settings are...I think just a little more minimum pressure will reduce those OAs.
The reason I wanted to know the breakdown was if the bulk of the AHI had been CAs or centrals then we wouldn't expect more pressure to fix things.
