Liters/minute or liters/second - PaytonA - 01-11-2014 I just read a reply that said that ResMed considers leaks above 24 L/m. My Resmed VPAP reads the leakage rate out as L/s. I have also seen other places where this difference exists including ResMed's website. Am I missing something? If this is all correct, it means that I should be concerned about my readings from the machine if they are above 0.4L/s, which they are constantly. I have been curious about this for some time but did not get around to asking until I noticed it on a post today. Best Regards, PaytonA RE: Liters/minute or liters/second - big_dave - 01-11-2014 You got it right. My S8 reports L/s like yours does, and it's converted to L/m on the ResScan reports. RE: Liters/minute or liters/second - justMongo - 01-11-2014 Mine reports 0.00 L/sec. If I were to get a leak, it would be at the full-face mask seal; and that would wake me. I tighten down my mask straps until there is no leakage. 0.4L/s is a lot of air leaking. So where is your setup leaking from? Your running a rather high pressure at 20/16 cm-H2O. Might be hard to get a good seal.

I am fairly sensitive to leakage and I do not think that is correct. Last night I got a reading of 2.7L/m because the hose came off of my mask and I awoke to the sound of my VPAP pushing a lot of air and I could not find the hose attached to the mask.
