The link to chestpubs no longer works. Can you update it?
I have the PR series 60 auto aflex set on 6 and 15. The machine is plenty smart but the person who set the pressures at the sleep lab wasnt so much. Every 30 hours the machine will calculate where its running most of the time where no events or snores FLs etc are happening and reset itself to start at that pressure. For me it figured out a 8.5 mean pressure where nothing much happens and it only has to bump up a little to level things if something does.
The trouble is set with a min of 6 if nothing is going on the machine will begin to lower pressure to get back to where it was set by the tech to start at which is 6. Normally around 7 things start to go kaput with a snore here FL there then and OA as the machine works its way back up in response to the events.
On my own I would set the pressure to 8 and that would be the bottom limit with 15 max just in case. But Im still on the 30 60 90 day medicare dance so while ive called to get my sleep doc to tell the DME to reset it, it takes while to get that done Docs being how they are about getting to anything in less than a week. My AHI is good so Im content at the moment to play the game and not tick off the Doc by setting it myself until im past the 90 day mark.
I hear ya Ghost guy, and understand your reasoning. However medicare and most Docs only care about how many hours did you use the machine, not what your pressures or ahi or anything else is. So while I understand the tendency to work with the sleep techs, if it comes to a point where your health or your therapy is compromised because of their recalcitrance then it's time to take matters (or cute little machine dials) in your own hands.
