Question

Quizplus · Accepted Answer

"Clubbing" of the fingers is a response to chronic hypoxemia, which occurs when the body is deprived of an adequate supply of oxygen for an extended period of time. This can happen in conditions such as lung cancer, pulmonary fibrosis, and other lung diseases. Clubbing of the fingers is thought to occur due to changes in the blood vessels and tissues of the fingers in response to the chronic lack of oxygen. It is not associated with CO₂ retention or acidosis, acute hyperventilation, or chronic coughing.
