Your first statement here may also be true (the second is not). But who is to say whether PSG data is that much better? According to the quotes from researchers who have studied this in earlier posts right here in this thread the big secret is that (Pssst! It's not!)

You also qualified this with "properly done". To me that implies an environment that is conducive rather than upsetting, and a full night's sleep as the basic sample. My study had neither of those, and if you read the posts, most who post here have anecdotally about the same experience.

Even if "properly done", a PSG is NOT definitive, for two reasons I stated earlier:

1. Events are never defined; they are on a sliding scale as to their duration, severity, and even whether they are one type of event or another. There is no black and white, until the events are counted up. Something has to be just over a particular threshold before it is even recognized. There is nothing exactly defined, and both the PSG and the APAP try to pigeonhole what they flag into defined categories for the purpose of simply counting them in those categories, as defined events, which they are not. That is like taking the Mona Lisa and digitizing it at a low, blocky sample rate and depth, and so there is a lot of guesswork where grey is supposedly either black or white, which it isn't. Its grey.

2. No measurement in either the PSG or the APAP back-pressure measurement is direct. No events are measured directly, because there is no way to do that. A belt around your chest that measures how much you expand your chest during a breath does not measure how you breathe, it measures how much you expand your chest, which is indirect, and the determination has to be interpolated from that indirect data. They are educated guesses based on secondary or tertiary data not even directly related to those events. That dithers the accuracy, eliminating the possibility of being "definitive".

And a PSG is a snapshot. One set of data points. A single sample set. The APAP gets a whole new set of data points every night, as conditions change.

Out of interest, is snoring and headache got better with the new machine and new settings, also what is AHI and leak so far?
You'll need to check "Essentials" set to "Plus" in the clinical menu so more info displayed on the screen sleep report and period set to 1 day (for last night data) default set to 1 month. Whenever the machine unplugged period revert back to 1 month

zonk: snoring stopped when therapy began Sept 11/15.

Still getting headaches but less severe than they used to be prior to therapy, but since getting the Elite machine there has not been any difference in the headaches. I am starting to wonder if there's more to these headaches, or if I just have to be patient. My sleep doc said it could take up to 6 months or more for all the symptoms to be resolved.

On the other hand, last 2 nights I have only awakened 1x each night! First night was at 3am but I got back to sleep fairly quickly. Second night awoke at 5am. So there's a definite improvement.

And I am not waking up in the night feeling like there's not enough air like before my pressure was raised. So another plus.

I am loving having stats to look at in the a.m.!! I think the RT must have set the "essentials" to "plus" because I am getting the following stats:
-usage hours
-events per hour
-mask seal
-humidifier
-period: 1 month
-days used
-days 4 hours +
-average usage
-used hours
-leak
-AHI
-total AI
-central AI

So you ask what is AHI and leak so far?? So since getting 2nd machine (A10 Elite)
Night 1 - AHI: .7 Leak: 10L
Night 2 - AHI: 1.1 Leak: 7L
Night 3 - AHI: .9 Leak: 11L

*** You mention whenever the machine is unplugged it will revert back to 1 month. I am assuming it won't wipe out the data on the SD card though? Cause I am leaving in the a.m. and it will be unplugged tomorrow and 2 or 3 more times before returning home in 5 weeks. My RT knew I was going away and didn't say anything about this.

Very good numbers, the doc would be pleased
Leak number means leak was or below this number for 95% of the night
AHI below 5 and the improvement you're noticing are an indication that the therapy is working,
Leak at or below 24 L/m is to aim for, yours much lower than that ... good job

Unplugging does not wipe anything, the period revert back to 1 month, just change it to 1 day, not big deal

Tongue Suck Technique for prevention of mouth breathing:
  • Place your tongue behind your front teeth on the roof of your mouth
  • let your tongue fill the space between the upper molars
  • gently suck to form a light vacuum
Practising during the day can help you to keep it at night
