OSCAR pressure graph

What does the two colors red and green curves represent?

[RPDM]

Red is inhale pressure the machine gives
Green is exhale pressure the machine measures

The difference you see between the two is your "Flex" setting. Based on your graph, Flex =2

When you disable Flex, then green and red almost overlap.

so what's with the spikes?

Dreamdiver educated me (us) there

Resperonics is upping the pressure by 1.5 cm to see if that helps you and if not, then returns to where it was. This is baked into the algorithm. It is also a reason why some folks prefer ResMed over Resperonics.

I'm not bothered by it, but can see how people experience it as a punch to the nose

I had a bad night last night and had to turn on the humidifer...... nose was clogged managed to clear it without Afrin. But had a shower of events after I went back to bed.

His Flex is likely set to 3, the Max.

Respironics' Flex is not a CM drop like ResMed's EPR. For Flex to get a 2 CM drop it's probably because it's on its highest setting (3).

I prefer to think of Respironics Flex setting of 1, 2 or 3 as Low, Medium and High.

My Flex is set at 3
