We originally got to S/T 24 years ago ( 12/1994 ) at about 2:30AM one morning in a sleep lab when CPAP totally failed.
More currently sleep lab 2/2017 resulted in ResMed Air Curve 10 VAuto with results:
OA 10.4, CA 12.5, Unk 10.1, AHI 37.3
Sleep lab May 2017 resulted in ResMed Air Curve 10 ST with results from (take note) 6/5/17 - 7/10/18:
AI 4.2, HI 7.9, AHI 12.1
....then with Air Curve 10 ST following surgery results jumped for 7/15/18 - 5/15/19 to:

Well - it will be up to respiratory specialist what he does at the time of my visit to him. What will be will be then.
Bonjour just sent a response about WIKi and requirements for ASV. I had read that before but will re-read it. One thing I recall is within three years there has to have been a change. I consider the change in July 2018 as a significant change. Another factor entering into it is approval to tritrate again which may not be too difficult with (1) changes, and (2) two years have passed. I'll cross that bridge at the time.
Step one - resolve leaks... I'll see what follows.
