Diffusing capacity is a measure of the ability of the lungs to transfer gas into the blood. Diffusion of gas to blood in the lungs is the most efficient when there is a high surface area for transfer, and when the blood is able to accept the gas being transferred Situations in which the diffusing capacity may be abnormally low include:

29 Apr 2019 Spirometry is a common test for lung function. It is used to diagnose asthma, COPD, pulmonary fibrosis and other lung diseases. It can also be

Diffusion of gas to blood in the lungs is the most efficient when there is a high surface area for transfer, and when the blood is able to accept the gas being transferred Hence, it has been proposed that spirometry with diffusing capacity may suffice in the physiologic evaluation of respiratory disease . To establish validity, future work should evaluate which combination of physiologic tests, including spirometry, static lung volumes, and diffusing capacity, yield the highest diagnostic accuracy and cost Algorithm for interpreting results of spirometry. (DLCO = diffusing capacity of lung for carbon monoxide; VA = alveolar volume.) To determine the validity of spirometric results, at least three D LCO or T LCO (diffusing capacity or transfer factor of the lung for carbon monoxide (CO),) is the extent to which oxygen passes from the air sacs of the lungs into the blood. Commonly, it refers to the test used to determine this parameter. It was introduced in 1909. The ERS/ATS standards for diffusing capacity specify a volume accuracy of ±2%, but the flow range required for the diffusing capacity maneuver is smaller than that for spirometry, and the systems measuring diffusing capacity primarily use higher-grade instrumentation. Therefore, laboratories using such equipment are expected to exceed accuracy If a restrictive pattern is present, full pulmonary function tests with diffusing capacity of the lung for carbon monoxide testing should be ordered to confirm restrictive lung disease and form a Diffusing capacity The diffusing capacity is a measure of the abil - ity of the lungs to transfer gas.3,4 Diffusion in the lungs is most efficient when the surface area for gas transfer is high and the blood is readily able to accept the gas being transferred.

In spirometry global, in addition to the two values mentioned above, the determination of two further parameters is also envisaged: CPT (total lung capacity) e Dlco (alveolar-capillary diffusion of CO).
