Been there-done that.
It was well run - I got hooked up at the clinic around 5pm and went home and returned the gear next morning.
I was diagnosed with Mod/Severe Sleep Apnea.
On the required follow-up the lady picked up what appeared to be a 3-4 page report - said I had Mod/Severe Apnea - put the report down - and without further ado went to the sales pitch - which model?
I said I would get back to them.
I discussed this with my GP and he recommended an overnight Lab Study for a more professional experience and result.
Expensive and not rebated by my insurer.
The specialist associated with the lab set a prescription of 6cmH20 and that was never varied although I was not responding to therapy at all.
The result was after several non-productive visits I binned the CPAP - subsequently had a rethink - and that is where I am today.
I will never feed those chooks again.
I believe - with the help of knowledgeable people on these forums - that the problems I have can be solved.
My last - although brief - session suggests I am getting close to a resolution.
Tonight: Amara View / 11cm H20 / C-Flex+ on 3 / Oximeter
See if I can improve on AHI 8.07
