try this:  http://www.askwaltstollmd.com/articles/rebounding.php     

not sure it is exactly it, but I went to www.askwaltstollmd.com  to search, and 
clicked on 'Articles on Health' link, then clicked the link to 'Emphysema and 
Rebounding'.

Hope this helps!

  Hello all,

  http://askwaltstollmd.com/body_rebounding.html

  In an earlier posting, this link was offered for information on the above.  
It is a broken link.  Does anyone know how to get the original info?  

  Thank you for your attention,

      Jim
