What is Emphysema?

Emphysema

Emphysema is a chronic disorder as a result of damage and inflammation of the alvioli (air sacs,which are used in the defusion of oxygen and CO2 from the pulmonary arteries and the lungs). This disorder is often secondary to longterm smoking. The damage and destruction of the alvioli results in a decrease of surface area available for oxygen and CO2 diffusion. These patients often rely on a hypoxic drive to breath.
