I use a ResMed AirSense 10 machine with a heated hose, and I just put the humidity setting on auto. The temperature is set to the default 27 deg. C. I have never had any rainout issues. An 8 hour sleep will use up nearly the full tank of water. The reservoir contains a maximum of 380 ml, so I would estimate I take in about 300 ml or just over a cup of water in a long 8 hour sleep. It is not a huge amount of water, and I expect 90% of it will be exhaled when one breaths out.

As for the fluid retention, what blood pressure drugs are you on? Indapamide may be a better drug than Furosemide for treating blood pressure and edema. It acts more uniformly during the 24 hour day than Furosemide. You also need to be sure your electrolytes (sodium, potassium) are in good balance. Things to discuss with your doctor.

That is very unusual. Have you set up the A11 the same as the S9? There are not that many differences between the S9 and A11, but one is that the A11 has two modes; the standard one and the For Her mode. The S9 would be using the standard mode.

From the graphs posted it seems you are breathing really deeply, because you feel you are short of air, I expect. The only time I have felt short of air is when the pressure is set or goes too low. But in your case it seems that IPAP is at 8 cm or higher, which should not leave you short of air. One graph you may want to display is mask pressure. It is a calculated pressure based on the set pressure and flow rate. It would be interesting to see if the mask pressure is staying up.

It would also be helpful to see the whole Daily report screen. On a PC you just press the F12 key to get a complete screenshot. It is also helpful to suppress the Pie chart and the full month calendar so more of the detailed setup shows. To suppress the calendar just click on the triangle beside the date. To suppress the Pie chart go to File, Preferences, Appearance, and uncheck the display pie chart box. The menu on the right if displaying can use up screen space too. I believe the F10 key toggles it on and off.

If you can post another chart with the mask pressure and the rest of the details showing, I may be able to offer further comments. Just post one screenshot as when you post multiple ones it can trigger the spam filter here and the post gets delayed.

My normal is to sleep on my back until I go to sleep and then I sleep on one side or the other for the rest of the night. Unless your mask starts to leak excessively, pressure should remain the same in all positions. There is a significant amount of intentional leakage (venting) out of a mask. That is how the machine keeps the air fresh in the mask, and how you exhale. The amount leaking due to the tube rotating should be insignificant in comparison to the intentional venting. The machine is adjusting the pressure all night to keep it correct.

The only issue with sleeping on your back is that in some people that increases the probability of having an obstructive apnea event. However, when using a CPAP the machine should increase pressure to prevent that from happening.

Bluetooth pairing can be tricky. This would be independent from the WiFi data transmission. All I can suggest is deleting the pairing and trying again with the phone close to the A11.

What specific machine do you have? About all I can think of is that FL is a flow limitation. In general they are not as serious as a full apnea event, and they do not factor into the overall total apnea index or AHI. Also in general a CPAP can help with breathing issues when they are being used at night, but do not contribute directly to assisting with breathing issues when they are not being used.

Yes, OSCAR gives you the ability to see what type of events you are having and when they happen relative to what the pressure is. This in turn can help you decide if the pressure settings on the machine are optimized for your needs. With an out of the box setup the machine is not likely to be optimum. And suppliers generally do not want to take the time to look at the detailed data to do much.

I have the AirSense 10 and my comments are based on it. I don't think the A11 is much different. The first point is that the machine has two levels of information stored. One is just summary level which there is an AHI, hours used, and summary leak type data. This high level data is all that is transferred wirelessly and available in MyAir. Much more detailed second to second data is stored on the SD card. That is not transmitted. This data is much more useful and can be accessed with OSCAR if you have a PC or Mac and a SD card reader.

But, back to your question, from what I know it is unlikely that your machine will send data when you are in Canada. If you go to the Clinical Menu you can see the wireless setup. Hold the round knob and the rectangular home key down at the same time for 5 seconds. That brings up the Clinical menu. Rotate the round knob down to the Configuration section, press it to select and then go down to the About section, and press to select. It should tell you what cellular network your machine is setup to use. In Canada I suspect it will not find that network, and I don't know of any way to change that network setting from the Clinical Menu. I suspect that has to be set in the factory or some other way.

But, this said the SD card will save both the detailed data and summary data if you keep it in the machine. It stores the last year of data. So, if necessary you can take that card to your supplier if they give you a hard time about not getting the wireless transfer of data. I would tell them ahead of time that you are leaving the country.

Hope that helps some

I have the AirSense 10, not the 11. However I am not aware of any difference in the humidity and heated hose features. When you plug in the heated hose the humidity setting should default to Auto, and if not you should be able to set it to Auto. That is where mine is set. And for temperature I set mine at the default of 27 C or 81 F. These settings work fine for me. I do use most of the water but never run out unless I am getting close to 10 hours of sleep.

Glad to hear it worked for you.

Some people get relief from obstructive apnea events with a soft cervical collar. They are inexpensive at places like Walmart. They may also work with snoring. They tend to work best when you are getting a whole series of OA events in a row due to your head and neck position. You will see if that is an issue when you look at your data with OSCAR.
