COMPLEX CENTRAL SLEEP APNEA

I am in an incredibly complex & life altering situation with complex central sleep apnea.  CPAP worsened the condition, BIPAP did not help & neither did BIPAP AUTO. After 4 sleep studies in one year I am on Adaptive Servo Vent (ASV).  I was sleeping 12-14 hrs straight & then 3 hour naps.  I have had the ASV for one week & feel no symptom relief. I am very concerned that this may not be working.
Dr Park do you have experience with ASV & do you know how long it takes to see results. I have had a diagnosed sleep apnea for 18 mos. Interestly, I too suffer from depression/anxiety. Anxiety meds can worsen sleep apnea I know.
I would appreciate any help and advice.
Any suggestions as to other medical conditions that may be causing exhaustion other than the apnea. I am on a thyroid med & levels are normal as is iron & B12.
Thank you

It's difficult to make a recommendation without looking at your entire picture (exam, history and test results), but most new CPAP modalities can take weeks to months before any benefits are seen. This is assuming that you're using the machine regularly at night and there are no leaks and your effective AHI is minimal.
