An explanation with more common terms would be appreciated. The medical terms and sentence structure make it difficult for an undereducated individual, like myself, to learn about the disease especially when suffering. 174.17.206.161 ( talk)
The second paragraph needs work. I'm not sure what the second sentence is trying to say. -- Jose Ramos 13:07, 11 Oct 2003 (UTC)
I just looked up the wiki on Finger clubbing, and it distinctly states that clubbing is NOT a symptom of a COPD, but may be a symptom of lung cancer. I don't know which is true, but this is obviously inconsistent and needs to be cleared up. - Jason Brown 04:32, 19 January 2009 (UTC) —Preceding unsigned comment added by Angryredplanet ( talk • contribs)
Emphysema sufferers are not blue bloaters. Blue bloaters describes another chronic obstructive pulmonary disorder, chronic bronchitis. Emphysema sufferers are called "pink puffers". That is they hyperventilate. Alternatively, because they hyperventilate, emphysema sufferers are able to maintain adequate blood pH levels: they are not cyanotic, which would suggest a low blood oxygen level. In bronchitis, there is a disproportionate loss of perfusion versus ventilation (ie. blood passing through the capillaries surround an alveolus which has no air supply due to a blocked bronchiole, will shunt into the pulmonary veins without picking up oxygen.) so even if people with bronchitis hyperventilate (up their tidal volume by breathing more) they will be unable to maintain adequate blood oxygen levels; so people with bronchitis, and not emphysema, will appear cyanotic. This is where the term "blue bloaters" comes from. "Pink puffers" and "blue older bloaters" are not deregatory terms, but are actually mnemonics. They help physicians tell the emphysema apart from bronchitis. It should also be noted that a patient can (and often does) suffer from both emphysema and bronchitis. Both conditions are initiated by an inflammatory response due to some sort of irritating or damaging substance enterying the conducting pathways and/or alveoli (ie. cigarette smoke, pollution, etc) Cigarette smoke paralyzes the action of cilia prevent the removal bacteria or other debris which may have been trapped in the airway. Trapped bacteria, can multiply within the conducting airways, and start an infection. Multiple infections lead to thicking of the tissue in the conducting pathways as well as secretion of excess mucus. These physiological responses can "plug" up airways (usually bronchioles) leading to bronchitis. In emphysema, constant inflammation results in destructive molecules being released within the alveoli. These molecules can damage the alveoli, causing the supporting structures of the alveoli to break down (including capillaries). This break down results in large, distended alveolus, that have a smaller surface area, and a weaker ability to take up oxygen from the lungs.

In chronic bronchitis true shunting as decribed above is unusual. Although sufferers of chronic bronchitis do have areas with low V/Q ratios the perfusion is maintained and a portion of air is oxygenated. Shunted blood does not make contact with inspired air and even supplemental O2 will not effect this. —Preceding unsigned comment added by BayAreaNP ( talk • contribs) 07:45, 11 November 2008 (UTC)
I excised the following paragraph. Someone with a medical background should take a lot at it and see if any material from it is salvagable. Zantastik 21:52, 23 Jan 2005 (UTC)
There's no mention of Centrilobar, Panlobar or Septal emphysema in this article. What's that all about...?
Ok, guys, put this in your pipe and smoke it: http://news.bbc.co.uk/1/hi/health/3329103.stm A study in the European Respiritory Journal shows that increased vitamin A consumption can return elasticity to alveoli in emphysemic mice. It may not be so "irreversible" after all. On the one hand, I don't want to justify smoking (I just quit myself). But on the other hand, if there there is any treatment that's even possibly effective, it should be posted. So I'm going to do that.
Yes, and bravo for quitting! Thank you for the input, and with everything typed, everything has been agreed, at least by me. lizardfreak96 ( talk)

I saw a section titled "notable cases" on the Alzheimer's article and decided to add one here. I am an emphysema patient and have taken an interest in Johnny Carson and Dick York's lives as inspiration of what I can still do before this takes me out. It is my hope that this section will do the same for others. I added ages at death, as well, to give other patients a better sense of the mortality of the disease. I find it comforting that the average age seems to be up in the mid-60's, even though I'm one of the youngest sufferers my doctors have ever heard of.
Removed Jessica Caroline Lunn from "notable cases". A Google search on the name only brought up 4 listings, two of which were this Wikipedia article. 68.62.15.243 13:22, 11 August 2007 (UTC)

This is not a symptom of emphysema. Tar stains wash off over time, surely? It's not relevant to the article: smokers who develop emphysema and then quit smoking will not have tar stains on their fingers. -- B.D.Mills ( T, C) 04:54, 27 May 2008 (UTC)
I think the article would be improved with some expansion to the section on Pathophysiology. The serpinopathy section of another article claims that "Well characterised serpinopathies include emphysema, cirrhosis, thrombosis and dementia." and provides a citation. I suspect there may be other causes as well, but was surprised to find this article mentioning nothing on it at all about the serpin connection that has apparently now been established.

This emphysema article lists finger clubbing as a symptom, but the linked finger clubbing article notes that finger clubbing is not caused by COPDs (of which emphysema is one--according to this article).
I'm no expert, so I don't know which page needs a correction.

To the untrained eye (that's me, and most other WP readers), the X-ray is uninformative. Could someone appropriately trained point out the features of the image that confirm the diagnosis? Cheers freestyle-69 ( talk) 22:38, 11 November 2008 (UTC)
If anyone would like to take the time to work it into the article, the discovery of lung stem cells was announced on 7-11-11. The article can be found here: http://news.yahoo.com/discovery-lung-stem-cells-may-herald-treatments-210407141.html . I tried to post but some well meaning doctor reverted my edits and I'm really not looking to become a skilled Wikipedian tonight, as he seems to be asking.
Same goes for my attempt to add Dick York and Johnny Carson [1] [2] to the Notable Causes list. Reverted by the doc. Both of their Wikipedia articles mention death by emphysema. If you know your way around and can post these "the right way", please do. 174.252.246.3 ( talk) 03:13, 12 July 2011 (UTC)

New study's findings on emphysema reversal — Preceding unsigned comment added by Fisiks ( talk • contribs) 20:37, 31 October 2011 (UTC)
Excerpt from Cell journal article:
"We provide evidence for a causative role of inducible nitric oxide synthase (iNOS) and peroxynitrite in this context. Mice lacking iNOS were protected against emphysema and PH. Treatment of wild-type mice with the iNOS inhibitor N6-(1-iminoethyl)-L-lysine (L-NIL) prevented structural and functional alterations of both the lung vasculature and alveoli and also reversed established disease." — Preceding unsigned comment added by Fisiks ( talk • contribs) 20:40, 31 October 2011 (UTC)
Based on the 2013 GOLD document [1] and this 2012 Lancet review Decramer, M.; Janssens, W.; Miravitlles, M. (Apr 7, 2012). "Chronic obstructive pulmonary disease". Lancet. 379 (9823): 1341–51. PMID 22314182. emphysemia is simply a pathological finding in COPD. It is not a disease in and of itself. As the treatment, diagnosis and pathophysiology all overlap I have merged this article into COPD (which was much better referenced than this one).

Page made from split of content on Pneumatosis page - Emphysema covers much more than that just related to COPD. On COPD page it is referred to without either its own section or detail.-- Iztwoz ( talk) 09:57, 31 July 2021 (UTC)
In the article it currently states "emphysema is a major subtype of chronic obstructive pulmonary disease (COPD)", and very shortly after that it states "Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers.", if emphysema is a subtype of COPD, how is emphysema without COPD possible?
