Quote:Keep all settings the same, but increase minimum PS to 4.0 and maximum to 7.0. Drink two beers with a piece of pizza, and call me in the morning.
Seriously, this should continue to control the OA that is looking pretty good. If it doesn't aggravate CA, then the result should be a bit better ventilation rate.
Quote:I dunno if it will help, but what I saw in your data was a respiration volume that seems a bit suppressed. As you can see in my data, the primary event is CA, but it is inconsequential being of short duration and not something to worry about. Not every night is that good, but if you're not feeling refreshed in the morning, it might be because you're in perpetual hypopnea with a suppressed volume.
Do you have the minute vent rate and tidal volume from before you changed the settings?
My suggestion is the same as Sleeprider's, that it would likely help your Tidal Volume to raise both Min PS and Max PS, such as perhaps 4 and 7.
Also, perhaps you are having Upper Airway Resistance Syndrome (UARS), and a higher setting for PS is the classic treatment for UARS.
I wouldn't be too concerned about a few centrals unless somewhat long in duration, such as longer than 40 seconds, or unless causing O2 desaturations. (This is where a recording pulse oximeter would be helpful.)
What were the settings which your doctor precribed, which you are now returning to?
