He says LOTS of things. (most of which I take seriously......in whatever identity he's using at the moment)palerider wrote:something sludge said a while back.Wulfman... wrote:Where did you come up with that value of "0.4"? Any links?
But, unless he comes forth and gives us a link to something other then the "PBE" (Play-See-Bow Effect - "PSBE"), I'll keep an open mind to other values. Like I said, I had values from 0.0 to 1.2 in a week of APAP pressures.....10 - 15 cm.

I often have AHI 0.0 and below 1.0 almost all the time.
One more thing to check: enable custom user events to flag durations >=3 s.

My impression is that sleep doctors, unless they are Krakow, don't generally pay any attention to flow limitationsprincessbelle wrote:I felt great when I woke up from my nap, been a very long time I felt good just waking up. I did take a look at my stats and saw that I should have started around 11. When the flow limit is so wacky is that indicative of nasal restriction? I don't seem to have any issue with breathing through my nose, then again I didn't have any issues sleeping either until that was brought to my attention. I have insurance, a specialist visit is a co-pay wondering if I should just make the appointment. I am learning what all the graphs are, what they mean and what my issues are. Thanks for all the advice.

For "Dr. Krackpot"?.......i don't think so.

He was also an advocate of these machines, too. And that was after they were already "dinosaurs".tan wrote:Oh, I'm not saying he is right and other doctors are wrong...

If anybody hasn't already read his postings here on the forum, he was quite active for a relatively short period of time.

Well, I guess it all started with one of the early ResMed patents, which statedWulfman... wrote:Where did you come up with that value of "0.4"? Any links?
If the flow limitation parameter is between 1 and a predetermined normal reference value, e.g., 0.65-0.8, then the breath is classified as "normal." If the flow limitation parameter is between 0 and a predetermined flow limited reference value, e.g., 0.4, then the breath is classified as "flow limited." If the flow limitation parameter is between the normal and flow limited reference values, then the breath is classified as "intermediate."

Yeah... I wonder if the value that the machine reports out is one minus that parameter?Wulfman... wrote:Is it just me or do those "parameters" sound bass-ackwards?

The switch happened about 5 years ago:

It appeared to be more than a flip and label change as the analysis went from "FL" to "FFL". This was discovered by LoQ who presented
