[Diagnosis] continue or not

[netsurfer]

I have been on a RESMED Airsense10 since 5/16/16 set on APAP 10 to 15 till 8/8/16
Settings changed to CPAP 8/9/16 thru 8/1/17 to 14 fixed.
Stats for period 6/1/17 thru 8/1/17 are below
Apnea Index    0.6
Hypopnea Index  0.2
AHI  0.8
Obstructive  0
Central   0.5
RERA index  0
% time in CSR    0

Changed to APAP  on 8/7/2017 to 5 min 15 max
claim is that if it settles out at 5 to 8 I probably done need to use the machine.
Virtually all events are central which as I understand CPAP does not help and even those are in the very low range.

Comments/ observations?
Thanks

"claim is that if it settles out at 5 to 8 I probably done need to use the machine."

Who said that? Pressure or AHI?

My impression: The claim is false.

[netsurfer]

I probably was not clear. If the pressure settles out at between 5 and 8 the machine is seldom working against Obstructive apnea events.
If you thought the 5 to 8 was AHI events I see the confusion. It was the Sleep Dr.that  suggested those  auto pressure settings

What is your sleep study AHI? Using 5 to 8cm is still treatment.

[Melman]

What were the results of your sleep study? If it was significantly higher than you see with your machine at 5-8cm, you need the treatment.

Here si the last 15 months of AHI from Sleepy Head

I'll by that settling out low may be a reason for a new evaluative sleep study without a machine.

An interesting chart. About 8% of the time with the new settings, you have "mild to moderate apnea", which is mostly central or clear apneas. No wonder you sleep specialist can't get a handle on you. You probably need to keep a log, recording what preceeds the nights when your centrals spike--- night on the town? big meal late? who knows? You may learn more by studying the Daily charts for those spike days.

I would suggest that you work on reducing your clear apneas by limiting your maximum pressure. Considering how rarely those spikes occur, it may take a while to arrive at the best pressure range

FWIW, those numbers are for TREATED apnea, not UNTREATED. Even with no apnea at all, I have to have a pressure of 8 or I will succumb because my heart beats too slow. So don't assume that a low pressure means untreated. A low pressure just means that you need lower pressure to correct your problem.

Couple of points that I should mention. I am down 30 Pounds....by design, not illness......since late April 2017 and have been on 
thyroid levothyroxine for 6 months. Being over weight and Hypothyroidism can cause Apnea or make it worse. I believe that those
are the extenuating circumstances precipitating the possibility that I could stop CPAP.
