I suggest that you raise your starting pressure to 7. Most adults find lower pressures leave them a little air-starved, and EPR (exhalation pressure relief) does not work properly. It would also be good if you turn ramp off. You get no real therapy during that time.
Your leaks are not terrible, but a little higher than we like to see them. If you
want to treat them, there are a couple of options. Some folks wear a headpiece called the Knightsbridge Chin Strap and apparently, it helps. Other chin straps are not good as they pull the jaw back rather than up. A lot of us use mouth tape. Many here like Cover Roll Stretch Tape, and it's inexpensive. I prefer Theraband Kinesiology Tape, as I find it more comfortable, but it does cost more.
Also, you would help us help you if you set up your chart just a little differently. We need to see the following items, in the order listed: Event Flags, Flow Rate, Pressure, Leak Rate, and Flow Limits. We need to see to the very bottom of the Flow limits.
Good luck with improving your therapy and comfort!
