Any downside to using static pressure vs range pressure?

Any downside to using static pressure vs range pressure?
I have only used my CPAP for probably a month at the most and in the beginning I had a really hard time to sleep. Someone on the board suggested putting the device on static pressure and I think it helped a lot. I started out at a static pressure of 7 and have slowly moved up to 8. (I have about 3-4 events a night)

My question is if there is any downsides to using static pressure vs having a ranged pressure? 

I am an extremely light sleeper so I am weary that changes in pressure will wake me up.

RE: Any downsite to using static pressure vs range pressure?
To answer your question as to what you may be losing while using a static pressure, would be for those nights where you need a little extra pressure to overcome an obstruction. Since you are at or near the minimum comfortable pressure for an adult, you would not be gaining anything by having the pressure lower. Like you, I am sensitive to pressure change. For this reason, I keep my pressure range to a 1-cm change envelope. That way, there is a little extra "oomph", but not enough difference to be noticed. Of course, a 1-cm change for you would represent a 12.5% increase in pressure, whereas for me, it only is a 7% increase. You can always try it and go back if you don't like it.

I always look for the live pressure range to be narrow and managed by handling events vs a hard limit on range. That said there are those that need either a fixed pressure or a solid limit to excursions. There is no one right answer

Thank you and sorry but what do you mean by "Since you are at or near the minimum comfortable pressure for an adult" ?

For an adult, any inhalation pressure below a 7-8 cm range seems to induce an air starvation feeling.

Ok thank you! Is there any downsides to actually having a higher pressure setting than one needs? Just to make sure one catches all the apnea events?

Aerophagia comes to mind, but don't worry unless it happens.

Mask leaks become more prevalent.
