you certainly would understand that:

I do.

I need to comment in case posting that (old) PFT was a test to see if I would say

"HF!! You breathe with that PFT!?"

RUFKM?

I was the resident misanthrope LONG before PR made his initial appearance.

I was hoping you'd be a good resource

No wait! Please stay!

I was really looking forward to serving you!

I'm also an ASPS, and I tell ya, DST can't get here fast enough for me...

Boy, I wish I had as much time for this as you do!

Funny you should say that...

...cause doing "this" is how I kept kishka on the table.

- simple Bernoulli's principle.

Yeah I saw how "simple" the Bernoulli Principle can be in your exchange with PR.

I am amused by the irony of that exchange in that Bernoulli is a "Conservation of Energy" principle.

I love simple arithmetic Great, I just happen to have a formula to fiddle with. people with larger such capacity (and I've posted about that recently). Yeah I remember. The minute ventilation thing. The vital capacity of ~7.0 liters. So back to our formula. Many labs use Cherniack 1972 to calculate...

Or run a comparison of VCom alone to Kricket.

Or fiddle with Rise Time.

Or that.

If it turns out that IPAPreduction is the next Big Thing IIWM I'd go back and dig up the old Proportional Assist Ventilation algorithms.

But IMO there's a question that needs to be answered before KPAP takes over the planet.

If KPAP is a comfort modality; and

comfort only applies to when you're awake; and

specifically, the hypothesis is that lower inspiratory pressures are more comfortable; then

why not just mash the Ramp Button?

At any rate, I would assume having a VCom in the circuit is the only way to do this as a machine on it's own wouldn't be able to identify and react to an inspiration fast enough. IOWs, Kricket is a workaround, and there may be a more efficient IPAP reduction algorithm in the works. By the other com...

Anyway, it looks like this is the Patent Application Publication: https://patentimages.storage.googleapis.com/f3/b3/90/20f31384fc601a/US20250032733A1.pdf So it would appear that the system will have a VCom in the circuit with additional IPAP drop from the machine: krick2.jpg I wonder if these reduce...

The role of vital capacity has everything to do with the ability of the CPAP machine to fill the lungs to the satisfaction of the patient, and thus - compliance, and has a lot to do with UARS: regulating pressure - at the source, not the destination - is a problem for some (like me), as what only m...
