Could it be so..........

If your showing a 0 leak with a PR machine something aint right. It would at least show the mask vent rate as leak.

If you look underneath the events breakdown on the left side of the detail tab, it says,"Time over leak redline". If one has had a good night it will be 0.000%. At least this is the way that it works for my Resmed machine.

Yep itll say that with the PRS1 but it says minutes in large leak. Theres also a percentage of night spent in large leak.

But the PRS1 only looks at total leak ie mask vent + unintentional leak.

It will show in the events 0 time spent in large leak if the leak isnt larger than about 70 lpm.

But there will be a leak rate. Even with no unintentional leaks the PRS1 will count the mask vent as total leak. In other words unlike a Resmed it doesnt care if the leak is intentional or not just that the total combined leak doesnt go into large leak.

If the leak graph is showing no leak at all with a PRS1 something is screwy.

But like one said if its working and no large leak just go with it LOL.

0% in large leak, does not tell us great deal other than the machine is coping and have no problem reporting events as it see them accurately. Unlike ResMed, Respironcis does not tell us what they consider as an acceptable leak number

Any leak large or small that keep one awake or causing too many sleep disturbances need to be sorted out
