It is best to have ramp turned off once you get used to the machine. In your case your pressure is so low ramp will not provide any value.

Clear Airway Events Only - New User Help

RE: Clear Airway Events Only - New User Help
For arousal breaths, you can see it with a 2-3 minute zoom where you have spikes in the flow rate. One cause is flow limited breathing that requires a deeper breath to “recover”. In your case you do not have a lot of flow limitations registering, but I expect in a zoomed view there are flat-topped inspirations that are flow-limited, which over time require the deeper breath. As you look at more OSCAR charts you will learn to recognise them in the full nights view.

Henry, interesting question…
My thinking is that the CA itself is just another event. What awakens you is the recovery breath as during apnoea events you are not breathing, so you take a big breath to recover which in turn brings you out of deeper stages of sleep. This goes on all night, which may keep you from reaching and staying in deeper sleep stages long enough to benefit from them. As a result, you wake up still tired. The respiration rate graph shows this quite well. You can also derive it from the flow rate. Which folks use is personal preference.
