Newbie seeking help to reduce AHI as low as possible - Oscar data

Can you share the snore graph for that March 1 report?

Yes, thank you!

The snore graph is a lot more active than we would like to see and it seems to correlate with the flow limitation increase as well.
Are you experiencing any nasal congestion at all?
If not then you probably need more minimum pressure. Probably up around 14 cm EPAP minimum pressure.

But if you are having a lot of nasal congestion then you need to treat the nasal congestion first by traditional means....meds, sprays, nasal rinses, etc/

I suspect your conclusion is "on the nose"! Yes, I cannot count on my nose for breathing at night, despite decades of meds, several otolaryngologists, and allergy treatments. I will probably just increase the minimum pressure and see what happens. I will also raise the maximum to 20 again; it appears I'm coming close to 19, and if it continues to top out at 19, no harm, no foul. Thank you for taking the time to look at my data and answer my questions!

The idea behind the increase in minimum pressure is to ward off or prevent any flow limitations or snores that might be happening when the pressure is a bit lower. Hopefully with a bit higher pressure the machine can do a better job of preventing the snores.
The snores are a sign the airway is trying to collapse abut your AHI isn't horribly high so it's preventing most of the snores or collapsing attempts from growing up into full blown apnea/hyponea events but not preventing the snores as much as we would like to prevent them.

A little more minimum gives the machine a better head start in it's work to hold the airway open better and more completely.

Snores should reduce somewhat or at least low enough to not annoy the wife.

That makes sense! Reduced snores are definitely better than the alternative: sleeping in the doghouse!
