That is still to the right of the area of interest with the three CA events. Just need to use the left arrow on the keyboard to move the window to the left so it covers them. See the area circled in red.

That is close. Can you shift the zoom window to the left to capture the beginning of the green CSR area so the three CA (magenta color) events are included.

Ok, it is probably best to see another night or two, hopefully with less leakage, before making any more adjustments. The one section in the middle of the night looks pretty good, but I wonder if you were actually asleep then?

Could you go back to Saturday March 23, and specifically to the start of the sleep about 23:00. There is a section highlighted in green indicating CSR. If you left click on that area repeatedly the scale will zoom in. You can fine tune the zoomed section with the up down and sideways arrow keys. The idea would be to get a highly zoomed in section that includes the three CA events that occurred during the CSR. If you could do a screenshot and post it, I would be interested to see what it looks like. That may be a clue as to what the nature of the CA events are actually about. Here is an example of a night when I was flagged for CSR. I have some theories in what is causing it, but need to see the nature of what you are having to be sure.

No need to go to all that trouble. Just use the orange Write a Reply button to start a new full width window. You can find it on the top right of the page or at least sometimes on the bottom left.

On doing the graphic I think it helps to go to a full page view with Oscar to do the F12 screen capture. After that no need to leave it at full page. Just close it and drag it from the folder where you saved it to.

I really can't see anything useful from your sleep reports, other than central apnea is the main issue detected. Without seeing your OSCAR reports which are much more useful than the sleep study information I can't really help you.

One thing to keep in mind is that a CPAP is not a "sleep machine". It cannot make you sleep when you don't want to sleep. In fact it can irritate you if you are not comfortable using it, and make it harder to sleep. Really all it can do is open the airway if it is closing (obstructive apnea), but you do not seem to suffer from that. If the airway is partly closing it can help with airflow by reducing pressure on exhale compared to inhale (EPR).

What the machine can do is report all the events which occur while it is on, along with what the pressure was at, etc. This can be helpful in diagnosing what is going on. But an OSCAR report is needed to do that...

What you need to do is look at your OSCAR daily reports. RERA events, Hypopnea, and Flow Limitations can be indications of UARS. Setting your EPR to full time at 3 cm may help reduce them.

Yes, some good things, and some not so good. The auto ramp worked as it should. Hypopnea, RERA, and Flow Limitations are down, which is good. However, OA events are up, and especially when the pressure is at max. My suggestion now would be to increase the minimum pressure to 10 cm, and the max to 13 cm to see if that helps with the OA events.

And as you can see the first part of the sleep was not too bad for mask leaks, but the second part was not so good. Perhaps more tweaking to the adjustments of the mask.

When posting screenshots it helps to get a full width window so the screenshot is larger on the screen. Use the orange Write a Reply button at the bottom left to get the full window. I have had cataract surgery and am trying to be eyeglasses free! That last post forced me to dig out my readers... I'm 75, the pleasures of getting old...

I should not paint all sleep clinics with the same brush, but many are really only in it to the point of selling a CPAP machine at a big markup. They pretend to offer follow up care, but really do not do much. Where I am if you get a "free" sleep study done and if you test positive for the need to use a CPAP they offer it at a cost of about $2500. Things have changes due to COVID and a microchip shortage but at the time the whole machine and mask kit could be bought on line for about $800. The difference is their markup.

The other little dirty secret of the industry is that the MyAir app sends very limited summary data over the air. If the clinic even looks at it, there is not much to see. However, AHI's over 5 should be raising red flags, and it sounds like it has not. MyAir is mainly intended for those who get their machine paid for by insurance or medicare on the condition that it is used a certain minimum amount. MyAir designed to measure that compliance, and not really to provide information on how the machine should be adjusted.

Approved clinics that sell ResMed machines should have a program called ResScan that produces similar report to OSCAR. The only way they can see the detailed data that you see with OSCAR is if you bring your SD card into the clinic and they download the data like you do with OSCAR and view it in ResScan. Only then can they see the details needed to evaluate what is going on and make good recommendations for adjustment. This takes time that they don't want to spend. Instead they want you to come in and do a sleep study which they can bill for.

Dirty secrets of the industry! But, I am sure some are much more responsible....

I don't bother to lock the cards before downloading the data. Both my machine and my wife's are AirSense 10's and I don't think they have this issue. Her previous machine was a S9 and OSCAR claims that might be a problem.

I look at that Daily screen primarily to see when the apnea events are occurring, and at what pressure they are occurring at, and of course the types of apnea and how much each contributes. Next I look at the Overview page. This has a bar chart by day which breaks down the contribution of each type of event. You can quickly see from that what types of events are occurring and if they are increasing or decreasing in response to settings changes. Last I look at the Statistics page to get a little more detail on the breakdown of events. This page will give a running average of your AHI for each setting. A new line starts each time you change the settings. It keeps a useful history of what setting you have tried and what the AHI outcome was for each.

A couple of comfort and convenience things you could consider are:

• Change the Ramp Time to Auto, and set the Ramp Start Pressure to 7 cm. Instead of ramping up the pressure based on time, it will start at 7 cm and hold there until the machine determines you are asleep. Then it will ramp up to your minimum set pressure. The maximum time it will hold is 30 minutes, and then it ramps up regardless. This can be more comfortable when going to sleep.
• Turn your Smart Start to On. This setting will start your machine automatically when you put the mask on and start to breathe. It will also stop it if you just remove the mask. However, my habit is to turn it off manually before I take the mask off.

Good luck! Post what you get with EPR at Full Time. That may make a significant change, hopefully for the better.

Another thing that some people do is move their machine and wear it during the day while watching TV or while on the computer. A big part of it is getting comfortable with the machine, and realizing that you are not going to suffocate or anything bad. A screenshot will be helpful even if you do not sleep. It will show where all the settings are at, and I may be able to offer some suggestions for improvement.
