the ball in the meter is pegged, I use a non rebreather type mask, but pull one of the side check valves off at night and even crank it back to 3 or 4 LPM because I fall back to sleep, normally I pull the mask off in my sleep and click off the concentrator, when I awoke this AM, the mask was off, but the concentrator was still running. I have not experimented with lower concentrations of O2, would think that anything greater than room 20% would be an improvement, pure oxygen can fry your lungs and I think that is going way overboard, your body still needs nitrogen to prevent your blood from boiling, guess moderation is the key.
