DSM,

I'm wondering if you've gotten your web page up. I can supply vent flow rates for 2 more masks if you're looking for more...

Thanks DSM. My other question is I have a Resmed Autoset Spirit & the leak rate is L/S. Which I think is litres per second. If that's right how does that compare with litres per minute.

thanks

Hybrid - InnoMed Technologies

Note: Its very linear from 7.5 cm/H2O on up.

cm/H2O>Liters/Second
10 > 48
15 > 60
20 > 70
25 > 80

Probably the clear winner in this race..

I'm not DSM, but I can answer that one for you. L/S is 1/60th of L/M. So multiply L/S by 60 to get L/M.
