I start at 10 and ramp down to 8. When it gets back up to 10 it wakes me up.

Are you unable to get back to sleep once it ramps back up? How long have you had your machine and/or is this a new thing that is happening?

What mode machine are you asking about? Ramp normally starts very low and progressively increases to enable folks to go to sleep more easily with the lower pressures. Most machines have a ramp function that the user can vary where the initial setting starts low and goes higher to max pressure over a time period selected by the user.

My pressure is 6-10. I do not have ramp function on as 10 is low pressure. I start at 6 and it will move up to 10 later on. Are you sure you start at 10 and move to 8 and then back to 10?

Either it is an autopap/autoset not a bipap or a bipap being used in a unique way opposite to what most people do. Each to their own. I use autoset and it definitely does go up and down during the night.

I was using 5 to 16 with a ramp up for years on a Resmed S9 autoset. In those days my 95% average was around 10 and peak was 14.

Using the Airsense 10 autoset I use 4 to 12 with a ramp up. Don't know why I used 12 but now my average is 5.7 for 95% of the night and peaks usually in the 10's. I have seen it peak at 12 very rarely but never for more than 3 to 5 minutes. I go to sleep easier with the 4 than the 5 and my apnea is better with the newer machine.

Having a good run at the moment and a recently acquired air purifier is helping to keep nasal passages clear (suggesting it is controlling allergies)

The lowest pressure any machine can be set at is 4 (with one or two exceptions, but those machines have been out of circulation for over a decade). The ramp can be set to start at any pressure and the time it takes is also adjustable on most models. I think what Gerbil is saying, is that their CPAP is set at 10 and when they press the ramp button it drops to 8. If you have a ResMed S8 or later machine (such as Wiredgeorge) there is no ramp button, but the ramp is activated every time you start it. You should be able to get any CPAP provider to drop your ramp start pressure and probably increase the ramp time (although without knowing the model of your machine it is hard to be definite on the available functions). This does not affect the treatment level, and so it should not require a visit to the doctor (not in Australia any way).

I have an Aircurve 10 and the ramp is turned off (I turned it off) and it starts at 4 anyway and rapidly goes up to 25. The backlight where you can see the pressure increase goes off somewhere in the low teens. Mine goes up to 25 in probably under a minute (inhale pressure).
