This imbalance develops chronic Hypoxemia, hypercapnia, polycythemia (increased red blood cells) and possible right-sided heart failure. Airflow limitation may also be caused by an imbalance of substances in the lung called Proteinases and Anti-proteinases. Over time, the inner walls of the air sacs weaken and rupture — creating larger air spaces instead of many small ones. The abnormal inflammation can sometimes activate the release of these substances, which in turn damage the lung parenchyma. 2005 Oct. 26(4):630-6. [Medline]. Am Rev Respir Dis. 2003 May 22.
