... I'm saving this one! This is really good and covers everything in a way I could understand. (Most of it).

Thanks for sending it along to us.

Diagnosing Pulmonary Fibrosis

Read this article that I thought was very good so passing it on to you guys P:

On visual > assessment, he has digital clubbing with cyanosis of his fingertips > and lips. On auscultation, he has bibasilar crackles. The lung >

practitioner orders several tests, which reveal pulmonary fibrosis.> > Definition> > Pulmonary fibrosis is one of many interstitial lung diseases that > scar lung tissue.
