Red line on the pressure graph

[Iamstumped]

Can someone explain to me why there is a red line on the pressure graph?
Sorry, but the forum attachments are full, again.

red inhale, green exhale.

red inhale, green exhale.

True, when the machine is using different inhale and exhale pressure.

In this image the "red line" is so faint, so short, so close to the green line that I really had look for it. It can't be EPR and it's beneath the green.

I have no idea why it appears there - first thing I'd do it is erase the data imported on that date
The next thing I'd do is make sure all my graphic drivers were updated
Make sure I'm using the latest version of OSCAR
And re-import the data.

tbh, i didn't look at the proffered graph.

BlueDragon may be interested.

If this is a bug in OSCAR, he might request you send him a copy of your SD card to reproduce the error.

And hopefully fix it.

I've not seen this before.

My interpretation: Your machine reduced your pressure very slightly. It could be that the data stream for pressure shows the reduction two seconds before the EPAP data stream. Could it be the result of OSCAR processing or graphing? I suppose so, but my first guess is that it is a glitch in the data.

I'll ask another developer to look at the graph and see if it looks like the oddity is worth pursuing.

[UPDATE] I see you posted this same issue on ApneaBoard. Our best guess is that it is a glitch in the data produced by the CPAP machine.
