David, on behalf of the SleepGuide Crew I welcome you to the forum. We appreciate our Professional Members though we often butt heads. This forum and others like it have a mission to educate those of us with sleep apnea and enable us to monitor our own treatment with data capable machines and software.
We learn that not every adjustment needs to be made by the doctor and a well educated, level headed individual can do some titration at home.
We do stress that changes are not advisable for new users and a team treatment approach must include us. We do not discourage folks from using their physician and in fact encourage people to keep their doc in the loop. Many docs are coming around and realize that we are able with the use of software to manage our treatment. We do encourage people who do not have support from the doc or DME to go "shopping" to find health professionals who are more supportive.
Your take on all of this would be welcome, and you are again welcomed to the forum.
