New to CPAP, Some Questions/Concerns

[CPAPrincess]

The lowest pressure your CPAP can produce is 4
The max reduction EPR can produce is 3
Therefore the lowest set pressure that will allow full use of EPR is 3 + 4 = 7. Thus 7 is the lowest pressure that will fully accommodate EPR

Ohhhh I see now, thank you. Also the sleep center called me today and said the doctor ordered the auto pressure to be set to a static pressure of 8 which increased my AHI so I'm going to set it back after a day or so but with a min of 7 as you suggested. Thank you!
