Hi all. I’m new to the forum. I’ve had my cpap for 3 months and am located in the uk. I’m currently in Italy and last nights update has not arrived in myair. I’m concerned that I may have upset the configuration for data transfer by accessing the sd card using the rescan software. I took a look at the detailed data, which was interesting, then closed it down making sure that I didn’t save any changes to the card. The data was uploaded the next day as usual. Could I have upset the system? I notice on the posts that I have looked at so far that there is mention of locking the card before putting it into the PC. I didn’t do that. But I only downloaded the data so thought it would be ok. Would this stop the data uploads? Thanks in advance.
I don't use MyAir, but instead use SleepyHead to monitor my detailed CPAP results. My understanding is that MyAir depends on the machine being able to connect to a local and compatible WiFi network to transmit the data to MyAir. Is it possible that the WiFi service that you normally get in the UK is not there in Italy? The wireless signal strength indication should be green, not gray, and not showing the No Wireless symbol.
Thanks Sierra. I’ll take a look at the sleepyhead software. I’ve not heard of it before. I have all bars signal strength so that should be ok. I’ve been in Italy just over a week so perhaps the sim has reached a data transfer limit. Home tomorrow.
Some links for SleepyHead. The software is free, but you need a PC or Mac with an SD card reader to use it. I find it very useful in tracking the detailed data these machines capture.
Thanks Sierra.
The data uploaded today. I managed a score of 100 but ahi was 5.6 which is a surprise. I definitely slept well though. The detailed data that I looked at last time showed that most of the time I'm at ahi of about 1, but it ramps up and then steps back down to the low value. I think I must turn onto my back or have done something strange with the mask... The step back down was at the time when I popped to the loo. I remember drool being involved when I took the mask off. Have others seen this ramp waveform on the ahi?
Thanks.
Most people are more susceptible to obstructive apnea when they sleep on their back compared to their side. Also some report that they can get their head and neck in a position that seems to promote OA as well, and use a soft cervical collar to help keep their head/neck aligned. The other issue is the type of apnea. SleepyHead flags all the individual events as well as the graphical trend.
These are the kind of things that SleepyHead is quite useful for. I believe your machine is compatible with it. The reports are a little less informative when using a fixed pressure. Here is an example of one of my nights when using a fixed pressure. You can see toward morning I had a cluster of events, but they were all central apnea (CA).
Thanks again for the help. I'll try the software this evening. I'm not sure I follow the difference between fixed pressure and variable. My machine ramps up the pressure and seems to lower it if I wake up to go to the loo etc.
Had another good night last night though hoorah!
Regards.

The difference between the AirSense Elite and the AirSense AutoSet is that you can only set a fixed treatment pressure with the Elite. The AutoSet machine allows you to set a minimum treatment pressure and a maximum. During the night the machine moves the pressure up and down in response to the apnea and snoring issues you are having. There is a movement toward the auto machines because they are easier to configure for the user and in most cases don't require the pressure titration study to be done to establish the right pressure. I have found for myself through testing that I can achieve virtually the same results with a fixed pressure as I can with a variable auto pressure mode. The trick is getting that fixed pressure right. With software such as SleepyHead on a variable pressure machine you can see at what pressures events occur and zero in on what an ideal fixed pressure may be. In your case with only a fixed pressure, it may be a little more difficult deciding if your pressure is right, or if it would be better higher, or better lower. On a simplistic basis if the majority of events are obstructive, then you may benefit from higher. If the majority are central events you may do better with a lower pressure.
In any case I think you will find the software very informative. You can post Daily sleep reports here to get feedback on how you are doing from other users.
