[ RadSafe ] Query re human pulmonary processes or mechanics.

[Maury]

Thanks, John.  I think the higher air pressure account is a major aspect 
of the pursed lips breathing. I've just never seen any data showing 
exchange rates as a function of pressure.  The rationale seem very 
sensible, but wonder if someone couldn't make a thesis or dissertation 
out of it. . . .<g>
Thanks again for the information,
