After proper polysomnography (API 51, O2 nadir 78%, many obstructive hypopneas, some central apneas (loop gain probably involved))
I will 30 day trial a bi-level machine, don't yet know which, but likely Resmed.
I wear a Wellue O2 ring to track O2, pulse and motion. Supine position is bad so I try to side sleep. Moderate deviated septum so use BreathRite strips.
In anticipation of needing to buy a bi-level (cost is an issue) I have started looking around. Resmed Aircurve 10 auto seems capable but more expensive than Wellue bi-level by a lot.
The O2 ring has been very good.
Not sure how the Wellue bi-level stacks up. It has all capabilities of Resmed10 but maybe the algorithms are inferior.
Any comments as I look at what I might consider (not limited to the 2 mentioned) would be very helpful.
