[Pressure] BiLevel titration study

I've read the entire list, and on many data points I find myself asking these types of questions, so wouldn't more info be a good thing?

So you mean in general, not just for tidal volume?

In many cases we get more information by watching how the value of something changes.

The most basic data items are leak rates and AHI. Hopefully the numbers for those are easily found. AHI below 5, and unintentional leak rate below 24 L/min are both "good".

Not so much in general, but even terms that are easy (at least for me) to understand, like 'respiration rate' - how many times did we breath on average per minute. OK, so I know that piece of data now. Great, I see it was 10-14, and today it's changed to 12-15, so? Do I care? Should I care? Do I want it to move? Go up, or go down? What's it mean if it does change? What if the change is small? I bet I could ask 4-9 more questions about this one piece of data, and yet it is plain to me what it means.

Now, take "VT" or "Tidal Volume", I read the definition, great, now I know what it means, but I still do not know how to interpret any change? Up or down, small change or large? Do we not want it to change? That kind of stuff. And, there are many more terms that I wonder about as well - which at this point, I tend to just ignore (which may not be very smart of me).

I do know how to research, and Google *is* my friend. But sometimes when we are busy it would be nice to have an answer spoon fed to us instead of needing to take the time to teach ourselves.

I also agree, all of this would make some very good WIKI articles tooSmile

We've sort of gotten of the rails on this thread.
It would be nice if we could get a "pro" to write a Wiki for us.
Most pros won't get involved.

I've looked further into Tidal Volume; and it seems to be a non issue except for people with COPD or are in acute respiratory distress.

My ResMed machine says mine was 380-680 last night. I believe the units are milliliters. The machine has to estimate this range because of factors like mask vent rate. The computational algorithm is likely proprietary.

An average tidal volume for a healthy adult is 500ml.

I'm not using ResScan because my S8 machine requires a special card and reader. But, I can look at the efficacy menu. It's there as VT.

Maybe only bi-level machines report Vt, tidal volume.


ADDED:

The tidal volume times the Respiration Rate is the Vm (minute vent or volume of air we breath in one minute).

So if ResScan doesn't report Vt but does report Vm and RR, then you can calculate the tidal volume as the Vm divided by the respiration rate.

Then it seems like a ResScan issue.
