Experimenting with a nasal masks. Will the leaks decrease?

[kong]

I used a nasal mask last night. Specifically, I tried a ResMed AirFit™ N20 Nasal CPAP Mask. Should I be concerned about my results and the excessive leaks? I don't normally wear a nasal mask. I was unaware of breathing through my mouth, although my results basically say that I did. Are the leaks likely to lessen over time?

It might be a little mouth breathing but it just as easily could be mask movement. I never worry about leaks when trying a new mask that first night. Sometimes it just takes little micro adjustments in the tension to deal with mask movement enough to cause leaks.

Whatever it was that caused it...5 % of the night and if I slept through it I wouldn't panic by any means.
If you like the mask then continue to give it a trial and maybe just do little micro tweaks with the straps and just keep an eye on the leaks.

It was roughly 24 minutes randomly throughout an 8 hour or so night.
For the most part you spent very little time above 30 L/min and actually up to 35 L/min the machine can do a fair job of compensating for leaks.
ResMed does the 24 L/min line for large leak territory but it a bit conservative and how badly a leak can impact things gradually grows the farther into large leak territory your go. You don't immediately go in the toilet at 28 L/min anyway. Now if you spent a lot of time around 48 L/min...different story.

It takes time and experience when learning about a new mask.

Try taping your mouth...that way you will eliminate the mouth breathing from the calculation.

following jays method of using scuncis across my mouth, i have eliminated mouth breathing. i'm a full bearded fellow and couldn't seem to get tape to work.

but the linked method works for me. perhaps it will work for you.
