Set CPAP to fixed pressure but OSCAR shows pressure decreasing all night...

Hi, 

I set my cpap pressure to 13 (fixed pressure with EPR, off APAP mode), but OSCAR is showing pressure decreasing all night until hitting 4 by the morning (with basically zero leakage). 

I've attached a photo. Is it plausibly just OSCAR glitching? 

One other unrelated thing: How can you tell what an arousal looks like from the flow rate? My flow rate is quite choppy and has lots of spikes. Is that indicative of RERAS (which is my primary issue)?

That's a data corruption or interpretation problem.

Yep, that's a data presentation problem that shows up with constant pressure. You can fix it by going to File->Preferences, selecting the Appearances tab, and then ticking 'Square Wave Plots' in the upper right corner. Or upgrading to v1.4.0...
