Understood!

Let's see if some of the other regulars agree or disagree with me.

I agree, but dont really care either way.

Graphic or link I usualy open in a second window.

I don't care one way or another.
Embeded does sometimes require an additional click to see image clearly but sometimes I can see what I need to see embeded without a click.

So I really don't care. I consider us lucky if we get an image in the format we need so I don't have to go doing more repeat instructions....again and again and again....when I have it plainly explained within the Newbies please read thread.

Did anyone have any thoughts on the chart if they were able to open it? I am just wondering if cpap is going to work should the Ahi be slowly (or quickly) going down or does it take a while. I guess I thought there would be more noticeable change.

it's a process that takes awhile. when you next post a chart(yes, you'll have to do it again so we see how the therapy is going) please be sure to tell us how you slept-lot's of wakeups? getting up several times to pee? brain fog or headache in the morning?

all of this will help you track how your therapy is going.

be patient and we'll see how it goes.

good luck!

Do you feel like you slept well? Or were you restless at times? How did you feel the next day? Excess sleepiness? Energetic or fatigued?

Something happened from about 12:20 to 12:40. You had a cluster of obstructive apneas. What position do you sleep in? Could you have rolled into a different position during this time?

The machine is showing a cluster of clear airway apneas after 5:20. What did your sleep study say? Did it note any central apneas? I'm thinking you might have awakened about 5:20 and just stayed in bed awake. The machines are good at reading events when you are asleep. When awake, normal breathing is so irregular, that the machine will often record clear airway apneas that are not apneas.

Do you have the summary of your sleep study? Removing identifying information and post it here if you can.

My sleep study was just a home study and only diagnosed OSA I even asked the doc about central apnea and he seemed to think it would pick up central apnea but I don’t see how, it was just a pulse ox and watch with a position sensor on the sternum. I didn’t realize it would be so minimal but I would’ve waited until end of July for in lab. i didn’t think I had apnea at first, but then by May I knew from a couple of the wearable devices that my oxygen saturation was low and even one that gives me an AHI. Sometimes moderate,sometimes mild, so I am not really sure how accurate (it is a ring). So I decided to do the home study and not wait. But what I actually went to the sleep doc for was severe insomnia back in April, which from what I have read actually can be associated with sleep apnea (the docs didn’t seem to think so).

I could have been awake and not been actually up at 5am but I try to take the mask off right away. I’ll pay more attention tomorrow. I don’t think I got up at all to pee or anything else. I don’t feel refreshed and do have brain fog and feel pretty terrible most of the day. Not exactly tired but more like fatigue I guess.

I just have never felt like I woke up gasping or airway obstructed but I guess most people aren’t aware of it. Husband hadn’t noticed but he notices very little And I never knew there was such a thing as central apnea until very recently. I am post menopausal which is about the only risk factor I have for OSA.

I’ll try turn off machine right away tomorrow. Do you guys recommend using the ‘smart’ start & stop function on the AS11 which stops automatically I think when you take off the mask ? I turned it off.

I did order a cervical brace for sleeping and a cpap pillow and I’m going to try the heated hose tonight. Oh and I do toss & turn a lot, I used to start out on my stomach but that is hard now so I’m starting out on my side and usually wake up on my back

Thank you for all the input! Sorry so long.

I would use the SmartStart on/off function both enabled if it were me.
It will easily start with just a couple of breaths and if for some reason you do end up taking the mask off during the night the machine will quickly turn itself off.
But it hurts nothing to turn it off as well. Gets kinda noisy with machine blowing if you aren't attached though.

I wouldn't worry so much about the CAs/centrals right now. I suspect you didn't sleep so great and that very well could have caused the machine to maybe flag some pauses in breathing while awake as a central apnea. Happens fairly often when people are brand new to cpap therapy. We just don't sleep so great at first because of all the newness.

If you do wake up during the night and have the presence of mind to reach over and push the button on your machine to turn it off and then push again to turn it right back on again that will create a little break in therapy when we know you were awake and if you happen to have a few centrals right before you turn it off and/or right back on again we can safely blame those centrals on awake breathing irregularities.

These machines don't have any way to know if we are asleep or awake because they only measure air flow and when we are awake our breathing is very irregular when compared to asleep breathing and the machine can and will flag those irregularities as some sort of apnea event (often centrals but can be OAs or hyponeas as well) and if we are awake they just don't count in terms of therapy itself. You have to be asleep for them to really matter.

Just concentrate on getting yourself comfortable with the mask and machine for right now.
We will worry about the centrals later if they continue but I am betting a good chunk of those centrals are false positive and related to awake/arousal breathing.
Besides...an occasional central is actually normal and expected. Centrals are only a problem when present in large numbers when we know for sure you were asleep.

Thanks Pugsy, if I use that smart stop does it only stop
If I take off the mask because it almost seemed like it would stop if you ‘stopped breathing’ but that can’t be right….
(Never mind I looked it up and the ‘smartstart’ starts with breathing, ‘smartstop’ is when you take off the mask

With the AirSense 11 model machines ResMed instigated 2 features for auto on and auto off.
SmartStart and SmartStop.

Prior to this new latest model ResMed only had one feature that did both. You couldn't separate the functions but now you can.

With both being turned "on" the machine will start blowing air once it senses your breathing and if you just take the mask off it will stop all by itself. It senses when it has a human attached to it or not. How it does it.....I think by some sort of back pressure thing but it won't do the auto off when you aren't breathing because of an apnea event...so no worries there.
ResMed never really explains exactly how it works....but it does work.

This is from last night only a few hours and I was prob awake until 2230 with all the mask leaks

Is this how I embed the image I don't think so

That's only three hours. If you used the machine longer, look in the lower left of the Daily Details report to see if all sessions are checked.

Unfortunately I think I took the mask off in the middle of the night with intention to put it back on and feel asleep instead.

Can anyone tell me how to view the pie chart on Oscar? It's never shown up in my view.

I am trying to read the Oscar info from sleep apnea board (is that a different forum?) but it's too detailed andI have no idea what eg flow limitation means and when I tried to read about it I couldnt really understand it - so is there like an Oscar for Dummies (or the sleep deprived) version? I don't really even know much about what each chart is about (tidal volume was another one).

Under the View menu, there is a Show Pie Chart option that toggles the display of the pie chart.

Be aware that when posting graphs displaying the Pie Chart is discourage as displaying it will take up valuable screen real estate. It is more important to post the configuration setting underneath it.

I'm not aware of much online material that is a good resource for learning OSCAR.

I learned by py posting graphs and applying what the more experienced users commented on. I also made a point of reading other peoples therapy threads and looking at the graphs and reading what the more experienced users said.

A lot of the OSCAR traces aren't of much value for the majority of therapy optimizing.

The real important traces (Daily Page) are:

• Event Flags
• Pressure
• Flow Limits
• Leak Rate

And the interaction of these values with each other

IMO, you are trying to run before you can walk. Priorities at this point should be using the CPAP all night, keeping the mask leak level within a good range, achieving an acceptable AHI, and getting sufficient restful sleep. (What little data you have doesn't show a problem with flow limitations.)
