I can understand why the FDA was hesitant to approve the Estimated oxygen variation (EOV) graph: with little guidance about what constitutes a "problem," it could/would create anxiety in a lot of people, and needlessly fill-up doctors' schedules as well as sleep labs (good for the sleep labs). If I bring it up with my doctor, I'm certain he'll take a "why not?" approach to a sleep study costing me thousands (even on forced socialized medicine).
Since my EOV graph has been activated, most days show a squiggly line in the low range. However, over the past 3 weeks, I seem to get a single spike past the "high" threshold once every 2-3 nights. Is this enough of a "problem" to schedule a sleep study?
Generally, what does the EOV look like for people who are eventually prescribed a CPAP machine (before and after the CPAP)? Or, have users seen some spikes, scheduled a one-night sleep study and were told that their sleep was normal?
Perhaps if Fitbit won't (or cannot because of the FDA) give guidance about what a problematic EOV graph looks like, we can crowd-source where that "see a doctor" threshold really is.
