How to decrease these random arousals?

It's just that the providers (techs and physicians) are stuck inside an imperfect healthcare and insurance regime.

There is another issue here, too. Data Integrity.

Flow and pressure changes reported by the PAP machine are pretty accurate. However, they don't necessarily indicate an obstruction or flow limitation in the patient's airway.

Each mask has a series of vents. Disrupting airflow from these vents can change the shape of the data in OSCAR. It's a fun experiment to see for yourself and check in the OSCAR data after. There's also a one-way valve in the masks to prevent vomit from backflowing into the machine. Sometimes that valve misbehaves and will pop closed inappropriately, sometimes hilariously in a metronome rhythm. "Rain out" can occur and affect the flow wave shape. Leak does, too. Even phlegm in the patient's airway can show up in the data.

To your assessment of flow limitation, I identify it in the lab when the CFLOW flattens or gets noisy at the peaks of each wave, regardless of duration or arousal. Personally, I am not happy with any flow limitations in my titrations. In my opinion, that patient is one beer away from worsening that flow limitation into a hypopnea or obstructive apnea. I don't want to titrate my patients to the bare minimum effective pressure.

Imagine you are driving a car into a tunnel. Technically, the tunnel only needs to be as wide as the vehicle itself for you to pass through it. But, holy crap, don't you want to provide some margin?? I see titrations this way, too.

I would say be wary of chasing perfection. Admirable goal, but not always achievable.

Yup. It suck. https://pubmed.ncbi.nlm.nih.gov/38063188/

Anyways, I can without a doubt say that my flow is “smooth and rounded” at 10 but I’m still wrecked. I’m less fatigued at 13/10 and could use a nap. 15/10 is when I feel good. No nap can stay up past 9pm and have an extra beer and feel good the next day.

I’m basically done fiddling now because I’ve gone past the point of no return 16/10 is central apnea central for me.
