I do, but I'm much further along than most who post on this board. I use 5 LPM when sleeping and 7 when I'm up and around. When I check my sats in the middle of the night, it's 97-98. During the day it's 98 at rest but can quickly drop into the 80s with exercise.
Thank you Tony, I did not think a little above 2 would hurt but like you mine drop fast on excertion. Mine are currently staying up real good but have been kinda taking it easy since ER Visit Friday. My Dr had previously said the same, increase as you need it but put a limit of up to 4 w/o talking to him first. Think I will stick with it for a few more days.
