In brief: Clubbing

Due to diseased lung and heart, as a cause of low oxygen to body tissues, there is a characteristic bluish color change and swelling in finger nail beds, called clubbing.
The exact cause for sporadic clubbing is unknown, with numerous theories as to its cause. Vasodilation (distended blood vessels), secretion of growth factors from the lung etc.

In brief: Low oxygen

Oxygen is not transferring into your blood stream if you have clubbing which is the nail finding you might be describing .
This can be due to heart or lung problems like cystic fibrosis or congenital heart disease

In brief: Clubbing

Congenital heart disease and cyanosis and severe lung disease are associated with changes of fingers and tips we look for that during a physical exam. There are other changes if fingers or nails with other conditions as well.
The lung related are like drum sticks called clubbing!
