...Stretch. Strictly speaking, the University of Arkansas' Dr. Richard V. Ebert told a meeting of the New York Heart Association, emphysema is a more or less permanent inflation of the lungs resulting from the loss of elasticity in their deepest recesses. There the tiny alveoli, or gas-exchange cells, give up carbon dioxide and take in oxygen. Clustered around small arteries, they are so numerous that they create a huge area for gas exchange-about 85 sq. yds. in the average adult...
...emphysema, not only do many of the individual alveoli lose their elasticity, so that they do not exchange enough carbon dioxide and oxygen, but much of the lung wall itself loses its stretch. The lungs tend to remain inflated. What the patient is aware of, said Dr. Ebert, is shortness of breath-especially when he begins to exert himself. The condition gets progressively worse until the victim finds himself winded after less and less exertion. Ultimately he is out of breath even when sitting still...
There has been much confusion between chronic bronchitis and emphysema, and some British authorities are inclined to believe that they are the same disease. Not so, said Dr. Ebert. Bronchitis, by definition, is inflammation and consequent obstruction of the branches of the windpipe. Post-mortem examinations have recently shown that one victim may have suffered from severe bronchitis and a little emphysema while another may have had the reverse. To distinguish between these two types in living patients with labored breathing, said Dr. Ebert, is surprisingly difficult. In fact, there is a continuous spectrum ranging from patients with pure bronchitis...
