Question

In trying to differentiate between chronic bronchitis and emphysema, you know that chronic bronchitis:

1. Usually occurs after age 50 and has insidious progressive dyspnea.
2. Usually presents with a cough that is mild and with scant, clear sputum, if any.
3. Presents with adventitious sounds, wheezing and rhonchi, and a normal percussion note.
4. Results in an increased total lung capacity with a markedly increased residual volume.

Answer 1

Chronic bronchitis normally occurs with respiratory infection after the age of 35 where is emphysema occurs after the age of 50. There is usually a persistent,

productive cough of copious mucopurulent sputum where is in emphysema there is no cough or scant if any high breathing sound.
