Diffusion Capacity
Diffusion capacity, often measured during pulmonary function tests, assesses how well oxygen and carbon dioxide move between the lungs and the bloodstream. It reflects the efficiency of the alveoli, the tiny air sacs in the lungs where this exchange occurs. A higher diffusion capacity indicates good lung function and effective gas exchange, while a lower value may suggest lung disease or damage, such as from emphysema or fibrosis. The test helps doctors understand how well your lungs are working and can guide diagnosis and treatment options.

Diffusion capacity refers to how well gases, especially oxygen, move from the air in the lungs into the bloodstream. It measures the efficiency of the lungs in exchanging oxygen for carbon dioxide. A higher diffusion capacity means that the lungs are functioning well and can supply the body with the oxygen it needs. Conversely, a lower diffusion capacity can indicate lung problems or diseases, making it harder for the body to get enough oxygen. Doctors may test diffusion capacity to assess lung health and diagnose respiratory conditions.
