Help with Resmed VPAPIII Data

I am trying to find out if these numbers (VPAPIII)on the resmed autoscan 5.4 are high or not. The AHI is 15.9 event per hour, AI is 3.0, HI 13.4 and time in Apnea 1.1% Mask on Time. I know those numbers are high. But What about leaks. Leak 95th centile 0.72 I/sec Median Leak 0.39 I/ sec Maximum Leak 0.87 I/sec. The settings are set from 14 cm-9 cm. The mask is a resmed Swift. I am thinking the problem is mouth breathing and might be solved by a full face mask or tape. What does the leaks look like with this data are they good or bad?

Thanks
