The image below can be my entry for your morbid
contest if you have one. Thankfully my OA was fixable. I'd bet someone would soon show much worse from from off a slab.
What you see is not the worst in regard to total time in apnea, TTIA, for a night. It is a spread with my longest apnea pair, 155 seconds (my greatest OA density for a 2+ minute period) interrupted only by a cardioballistic-like wave. The 155 here and elsewhere had lots of lengthy neighbors, numerous ones over 100, up to 120.
The graphic attests to my then-total ignorance and to poor MD guidance, as an apneic himself, after his Rx-ing the best machine for me (IMO).
You can see why I was frantic my fourth CPAP night with troubled ignorance, FFM leaks (that noisy thing, so many other nights on my face) and a machine set to 7 cm H20 on CPAP. Hoping this was not normal therapy nor my future, I began looking for help from MD, DME and online.
My "Call for Excel VBA help ..." thread in the Software Forum has as its main work image one from November 2015 that shows OA nearly eliminated, but with lots of remaining FL. It shows the effect of sleep positions on FL-flag indications of breathing flow limitations before I added a cervical collar to my sleep armory. Much improvement followed, thanks to AB guidance one way or another
My simple OSA as above was soon tamed by the Autoset and its titration advice here at AB--some from merely lurking here, one or more times by direct posts.
I eventually got SleepyHead, thanks to ApeaBoard, and was able to look back amazed at such things.
---Gotta!
The LORD has given me just over 6 more years and much more unearned favor--some not enjoyed at all at the time. But I am not on that slab yet.
