My newest Doc did not review the best data available before recommending new equipment. She never looked at current data on my CPAP (90 day record), nor data I have kept for 5 years to show trends. Used a 2 yr old sleep test and one night record from a recording pulse ox (which I provided from my equipt).
She used the result of one night of sleep testing to diagnose I needed a new mask. (I have only two leak events recorded on my CPAP in 90 days) It is likely I pulled it off during the test due to puffs from her new machine that were out of synch with my breathing pattern, or the slip knot on my old strap probably loosened during the night with repeated checks on the glue in my hair. I do need a new strap (adjustable preferably), but don't need a new fitting. I use nasal pillows which seal 100% if the strap is right.
How I feel about her, and whether she had a bad day or not, are irrelevant. I think these are objective observations I have made. I consider this lazy and incompetent. I won't be going back.
When I had Afib, the docs were just going to put me on heart drugs. I had to insist on testing for root cause, which came down to bad settings on the CPAP causing increasing central apnea events.
