Sierra

The MyAir app is very limited. It is more intended to measure compliance to using the machine. Some that get a machine are obligated to use it to a certain level, so they can keep it.

Those who want to look at their results in more detail use the free program called OSCAR. It allows you to view all the detail from minute to minute such as pressure through the whole night. You do need a SD card reader and PC or Mac to use the program. The AirSense 11 machine is very new, but I believe it has preliminary support in OSCAR.

This is an example of some of the detail you can see with the program.

Another thing you could try, assuming all your data is still on the SD card (and it will be if you have not deleted it), is to create another profile in OSCAR with a slightly different name, and then import the data from the SD card again to this profile. This time I would suggest not selecting any time zone information, to see if that helps with the problem.

It sounds like bugs in OSCAR. Have you downloaded the most recent version? It appears 1.3.0 Is the current version.

From a quick look on line it appears the data has been encrypted on the DS2 machine and OSCAR is currently unable to read it. The OSCAR team are apparently still trying to get through the encryption, but to date have not been successful. If you have any option I would suggest the ResMed AirSense 10 AutoSet instead. It is fully compatible with OSCAR.

That is a little puzzling. I checked my settings on the File, Edit Profile, first page screen. I don't have the country entered, nor the time zone, and the DST Zone box is not checked. My time is correct. I think I would try that first. Just don't put anything in there and then OSCAR should get the time from your AirSense data.

But, just to confuse things a little. I then checked my wife's Profile, and she has the country entered, the time zone, and the DST box checked. And her time is ok too. If worst comes to worst, you could fudge the time zone in the setup to get the time correct. I do not think that will impact any existing data.

We are using SleepyHead, so there is a possibility that OSCAR is a little different.

I think that is it. On a ResMed when you use SleepyHead or OSCAR you can see the actual mask pressure and would be able to tell if it is working. The DreamStation only shows the set point for inhale and exhale pressure, not the actual pressures. It is one of the limitations of a DreamStation. Other things maybe mask related, if the mask is somehow blocking exhale. See the other recent thread on that issue.

Once you have installed OSCAR you should only have to put the SD card into your computer and follow the instructions. There may be a bit of a registration process, but I just put the minimal amount of info in there. If you want to post your reports on line, you don't really want any personal information to show. It can handle multiple users, so you do need one name to distinguish between the users.

That is a good question I would like to know the answer of too. My wife needs a machine to replace her aging S9. Last time I checked prices have not started to come down. I have seen something to the effect that these AirSense 11 machines are only being sold so far through sleep clinics and not through on line cpap equipment places. The only good prices I have seen are on the DreamStation machines. Nobody wants them now they had that recall due to the foam issue. It is tempting to get one that is updated with the fix as they are nearly half as expensive as the ResMed AirSense 10 AutoSet's.

I was thinking further about your blockage problem. You may want to consider cutting slim pie shaped pieces out of the nostril prong part of the mask. That would seem to allow the prong to still located the mask properly with the RemZZZ's, but reduce the chance that the split parts of the prong would collapse and overlap to block the airway.

There is not much setup to do with OSCAR. I like to do a few things like clean up the format of the Daily Report layout. Here are some suggestions:

• By default I believe there is navigation menu on the right side of the screen. The F10 (on a PC) hides it to give you more screen space. It is a redundant feature in any case.
• Under File, Preferences, Appearance, I uncheck the box which says "Show event breakdown pie chart". It takes up valuable screen space and is also redundant. If you want to post this screenshot here, the pie chart displaces other more important data so it will not show. The only downside is that if you get a zero AHI score the big happy face will not display!
• There is a black triangle beside the date in this screen that shows the whole month by default. Again it displaces more important data. Click on the triangle and it will hide the full calendar. Click on it again when you really need to use it.
• If you right click on the vertical Leak Rate Scale it will show a menu of options. Select the "Dotted Lines" option, and then check the box that says "Leak Rate Upper Threshold". It draws a red horizontal line on that graph to show the suggested maximum acceptable leak rate. I find it handy as a reminder as to whether leaks are a problem, and when during the night they become a problem. I also fix the vertical scale of this graph to be 0 to 50. This prevents OSCAR from auto scaling which can distort the severity appearance of the leak. You may also want to fix the scale on some other graphs so they display similarly from day to day.
• You will probably want to rearrange the order of the graphs so the default screen shows the ones of interest to you. I will post my current layout as an example of what I like. This will vary depending on what your issues are. I include "Minute Ventilation" as I find that is a telling characteristic of central apnea that I suffer from. I have few snore issues for example, so I move that down.

My basic routine of looking at the data is to first look at the Daily Report to see when the apnea events occurred. If there are say a series of events or a cluster, I will left click repeatedly to see more detail. It is amazing the granularity of the data right down to each breath. You can also use the up down arrow keys and left right arrow keys to look at different areas of the night. If there is nothing further of interest to look at, then I click the Statistics tab to see how I am doing with my current settings to see if everything is stable or possibly improving. This screen is useful in displaying what setting have worked the best (highlighted in green), and the worst (highlighted in shaded red). Last I click the Overview tab to see if I can see any trends especially in the type of apnea events I am having. It also displays what your total time in apnea is each night, which may be of interest to see if there is a trend.

There is more you can do to investigate issues, but this is my basic routine. If you have any questions just ask...

If you want to post a Daily report here for comments that is a bit of a trick. You first need to display the Daily Report full screen and press F12 (on a PC) to save the screen shot. A message will display temporarily in the bottom right of the screen to show where it got saved. Take note of that so you can find it with File Explorer (PC). In File Explorer when you find that screenshot file, left click on it and then drag it into an open message here that you are composing. Best to only post one screenshot, as multiple images can make the post get hung up in the spam filter. For the best detail start your comment with the orange "Write a Reply" button so you get a full width image that is easy for people to read without resorting to other tricks. I will now break that rule and post my screenshot for last night in a reduced width window! But best to avoid that if you are looking for comments from others here.

Quite frankly, I think it comes down to the fact that some people are too lazy to change their clocks twice a year....
