process is usually pulmonary fibrosis (scarring of the lung). As the disease progresses, the normal lung tissue is gradually replaced by scar tissue interspersed with pockets of air. This can lead to parts of the lung having a honeycomb-like appearance.

Diagnosis

In restrictive lung disease, both forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) are reduced, however, the decline in FVC is more than that of FEV1, resulting in a higher than 80% FEV1/FVC ratio.
In obstructive lung disease however, the FEV1/FVC is less than 0.7, indicating that FEV1 is significantly reduced when compared to the total expired volume. This indicates that the FVC is also reduced, but not by the same ratio as FEV1.

One definition requires a total lung capacity which is 80% or less ofStoryline:Award-winning CBS news producer Mary Mapes (Cate Blanchett) and newscaster Dan Rather (Robert Redford) are a well-rehearsed team known for their investigative reports. Together they lead the news program "60 Minutes". One of their revelations caused quite a stir in September 2004 and has far-reaching consequences for the journalists. As the investigations by Mapes and Rather show, George W. Bush refused to join the Vietnam War as a soldier. During his military service in 1968, the Bush family was said to have used their influence to spare the future president of the United States from deploying him instead of preferring to join the National Guard. With their story Mapes and Rather unleash a public scandal and a media response that hits them with great force and their careers
