[Pressure] BiLevel titration study

[justMongo]

This titration was done in a sleep lab with all the bells and whistles.

The time spent at each bilevel pressure combination seems very limited to me.
How would they decide that 14/9 cm-H2O was best based on this data???? (Looks like data after 14/9 was all too short in duration to even consider -- so, they picked 14/9)

And, am I seeing mostly central events?
Why select a VPAP S if CA is a problem. Isn't a timed mode also needed for CA?

Hi justMongo
This titration protocol guide from Phillips Respironcis might help answer your question

Excellent.. thank you. I've not seen that.

Can anyone define the term: Tidal Volume?

Can anyone define the term: Tidal Volume?

From the Apnea Board Wiki Definitions page (here):

Tidal Volume - The amount of air that passes in and out of the lungs in an ordinary breath. Usually expressed in liters.

The only thing I wish, is besides a 'definition', there would also be more info like - more is better - or, an average person has a VT of XX - or - something to explain how to use this data item - is less better, is more better? Does this make sense?

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?

I agree with PeterC. Having some indication of a target value would make the definitions much more useful to those seeking knowledge.

We're always looking for new Wiki Editors who can help expand the Wiki articles with info like that.

Read this thread for more info if you're interested:

Kind of hard to edit something you do not understand and/or are not knowledgeable about - hence my suggestion

Agreed. I don't totally understand it myself; perhaps someone here does who might offer a full explanation that can be included in a Wiki article.

Now that you're a Wiki Editor, Peter.. if you or someone else wants to create an article on Tidal Volume, that might be a good thing. The Definitions & Glossary Wiki Page isn't intended to be a complete article on any one subject - it's only a short definition. So the way to go is probably to create a new Wiki article on Tidal Volume perhaps.

Just a thought.
