Scroll down to the end of the article for the explanation on the ASV Machine.
MakeSleepaPriority, the situation you have described would be ideal but sadly, that isn't happening in real life. Heck, patients with cpap, apap and bipap machines can't get their sleep doctors to thoroughly look at the datacard. They simply look at compliance and AHI and if all is well, they send you on your way.
By the way, I hope you teach your patients how to access software and download the datacard so they can understand what is happening and spot potential problems they need to bring to your attention. Sleepyhead software, which is free and is a great program, works with many ASV mahcines.
You might want to head over to www.cpaptalk.com where members would show you how to download free sleepyhead software and see if therapy is optimal. There aren't as many ASV users but the ones that are there could help you interpret the data and provide advice on how to make adjustments.
I hope this helps.
