It struck me as redundant with everything that was already discussed in the previous section (about spirometry). Perhaps it needs to be moved. JFW | T@lk 21:03, 7 December 2013 (UTC)
From my understanding the FEV1 percentage of normal is used to determine severity while the diagnosis is FEV1/FVC<0.7. Slightly different. Doc James (talk · contribs · email) (if I write on your page reply on mine) 00:30, 8 December 2013 (UTC)
I had a closer look, and I agree that the sentence is needed for the rest to make sense. I've put it back. JFW | T@lk 07:21, 8 December 2013 (UTC)
I have come across bullous emphysema in an accident report of 1952 (see Easington_Colliery#Men) which is (apparently) "distension of the air sacs to blister like formations on the surface of the lungs". In the case I am researching a man suffered a rupture of a bulla leading to a partial collapse of the lung. [[emphysema]] leads here, and yet as a non-medical reader (WP:RF) I can find no mention of this form. If the old bullous emphysema is a form of COPD perhaps a sentence or two could be added. If it is classified differently today then could someone add an appropriate hat note please. Thanks, Martin of Sheffield (talk) 21:02, 4 May 2014 (UTC)
This is simply emphysema with bullae. We mention in the article and have pictures. Doc James (talk · contribs · email) (if I write on your page reply on mine) 21:04, 4 May 2014 (UTC)
I'm a casual Wikipedia user, so forgive me if this is way off base. The article quotes "The number of deaths is projected to increase due to higher smoking rates and an aging population in many countries", should we also mention the increasing amounts of COPD due to surviving the 9/11 attacks? I just feel like it could be a good addition.
To include this, we would need a very strong secondary source. It bears remembering that "only" at most 100,000 people were exposed to the fumes, which pales in comparison to those exposed to cigarette smoke and smoke from indoor domestic fires. JFW | T@lk 18:03, 7 May 2014 (UTC)
"In 1953, Dr. George L. Waldbott, an American allergist, first described a new disease he named "Smoker's Respiratory Syndrome" in the 1953 Journal of the American Medical Association. This was the first association between tobacco smoking and chronic respiratory disease. "
