Seriously?did you *have* any events?
it's impossible to tell the duration at the zoom size shown, how long were your pauses? could be, that as crappy as that was, you didn't have anything that would be classified as an apnea.
There were no events flagged by the 960 while PS was set to 0. The only events flagged are from my pulse oximeter, and I am pretty sure SH flagged those. I have zoomed in. There are flat-line pauses between the groups of breaths that last 10-20 seconds. Apnea aside, the reduction in flow rate should have triggered flow limit, hyponea, and periodic breathing flags. If my breathing looked like that and the machine said all was OK while it was operating in a normal mode I would have some choice words for PR. I bought the machine so my breathing wouldn't be like that.
It also did not report leak rate, mask pressure, repiration rate, MV or any of the other things that are normally report.
