Hyperinflated lungs

Discussion:

Hyperinflated lungs are present in many chronic chest conditions in particular COPD and asthma.

This may be evidenced by:

a. Flattened hemidiphragms

b. Hyperlucent lungs ( less bronchovascular markings per cm2)

c. More than 6 anterior or 10 posterior ribs in the mid-clavicular line at the lung diaphragm level.
