Silverlining Leak Rate

Can someone explain how to interpret the leak rate numbers in Silverlining? I'm used to Respironics giving the complete number (eg: 32) from which I subtract the mask mfg recommended number for my pressure. But Silverlining shows 0.4 or 0.5 consistently, despite that the PB 420E does not know what mask I am using.

SilverLining reports the leaks in liters per second, l/s. In order to get the number in liters per minute, you have to multiply it by 60.

Well I was pretty sure I remembered your saying that at some point, OziJ, but the resulting number (24) just does not correspond to the consistent number (32) that I get at same pressure with same mask, using my Respironics APAP. How can there be that much discrepancy, I wonder? On the other hand, my AHI's are generaly lower on the 420E than with the Respironics, all other things being equal (no flex, same pressure range apap). Hmm.

Any thoughts on this? Perhaps I just do better on the 420E? Wish I understood it better.

If you're wondering about the numerical differnce - 0.4 or 0.5 x 60 vs. 32, then I think we can chalk it up to unreliable measurement - and - feeling_better has been tracking that issue, see ]A detailed investigation into leak data reports[/b] for instance.
