Am now a week into auto use set at 6/9. The pressure pattern over the week seems to have settled down to a fairly even pattern.
Last night I had my best AHI result to date ( over 3 weeks of machine use) of 0.52 but was also my worst night to date.
Basically I slept fine until early morning (around 5:30am) when things went downhill.
I have attached a screenshot from Sleepyhead showing the notes I made this morning & would appreciate comments from those more knowledgeable than myself. Please feel free to request specific enlargements from sleepyhead if required.
I am aware that others have previously posted similar & the comments have been around anxiety issues. I did not feel especially anxious (& as a retired psychiatric nurse therapist consider I possess the self awareness to make that statement), or scared as I was aware I could remove the mask. I persisted however for a while to re-establish a normal breathing pattern, but eventually admitted defeat.
Below are expanded copies of the flow rate wave pattern, showing my normal breathing pattern, & the breathing pattern when I felt I was struggling to get sufficient air. To my untrained eye the two don't look hugely different, but they sure felt different!
EDIT: Now a couple of hours or more since I got up I feel fine.
