The last two nights, I experienced the bulk of these events in the last 1.5 hours of sleep. My wife gets up early with our toddler, so these last 1.5 hours of sleep during weekend days are typically on/off sleep.
Another note of potential importance, when I nap I have 0 AHI even if the nap is 2 hours long. I am only experiencing these bunchups with my overnight sleep. There are extended periods in every night of sleep that I experience 0 events.
If I'm interpreting the chart right, I am experiencing many of these central events during wakeups and when the pressure ramps up over 10. I often notice that when I wake up, the pressure is typically very high. Last night, I woke up with my mouth full of air and the pressure at its peak volume.
Please let me know how to interpret these events. And yes, I'm aware that my AHI for these nights is acceptable, but if without the Central Airway events, my AHI would hover around 1 or less every night, so I want to get these taken care of. I have been experiencing many issues with mask leaking, too, if that information is helpful.
