To me, these were all indications of a crappy night's sleep. Woke up almost 7 hours later with AHI of ZERO ! I am certainly happy, but seriously starting to question the validity of these #s. Perhaps increasing the ramp pressure to 8 for 15 minutes helped. It was previously set to 4 and AUTO.
doesn't a flat line like these indicate an issue?
I'm /guessing/ that the top line is flow and the bottom one pressure. Both flat lines last for 8 seconds or less, too short to score as either obstructive or central apnea. The little bumps in pressure are probably Resmed's attempt to differentiate between OA and CA; the tiny bumps in flow might indicate an incipient CA - which you aborted by starting to breathe. If that's all you found, no problem. If there are lots of those, then probably toning down the drink should take care of it. One night is not the rest of your life.
I hope others more experienced will comment as well.
