Exhalation port- can it make higher leak numbers?
Hi ya'll,
Is it possible any percentage or amount of leak number different with the Nuance I used last night, over the p10 I usually use, could be from the way or amount the Nuance blows out of it's exhalation port?

Thanks,

Google the Vent rate for Nuance mask. The P10's venting rate is 20L/min at 4cm and goes up from there. Nuance may have a bit higher vent rate given that its rated from 3cm-20cm pressure and P10 is from 4cm-20cm pressure.

Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.

It is doubtful that the vent area will effect the leak data on Resmed machines and I would presume on PR machines as well.
