I'm on 11 psi, my mask is a Simplus and has no adjustment. 11 psi is fine with the mask but with the pillow it's just to strong for me, my doctor recommended to try 9 psi.

What PR means is that you don't need to adjust the pressure to suit the mask. You may, however, need to change the mask setting (I don't have a Respironics, I have a ResMed, and it has a setting to adapt to the mask type) My mask doesn't have adjustable settings, my specialist advised me at my last...

I need to reduce the pressure on my Remstar Plus C-Flex. I found a site that showed how to do it for a ton of cpap's but not my model. The reason I need to change is when my allergies are bad I need to change from a nasal pillow to a face mask.
Thanks, Matt
