2020-05-14 · Spirometry and pulmonary diffusion capacity tests were administered on the day of or 1 day before hospital discharge. Results revealed anomalies in diffusing capacity of the lungs for carbon spirometry (n 2,586), static lung volumes by helium dilution with inspiratory capacity maneuver (n 2,586), and hemoglobin-adjusted single-breath diffusing capacity (n 2,508). Using multi-variable linear regression, adjusted least-squares means (adj LS Means) were calculated for TLC, FRC, RV, and hemoglobin-adjusted single-breath diffusing The GLI Spirometry Task Force derived continuous prediction equations and their lower limits of normal for spirometric indices.

Spirometry diffusion capacity

The degree of severity of reduction in the diffusing capacity can be assigned according to the following scheme: less than the predicted lower limit of normal but greater than 60% of predicted is DLCO stands for the diffusing capacity from carbon monoxide in the lungs. A DLCO Test is performed to assess the extent to which carbon monoxide can diffuse from air into the bloodstream. During the test, carbon monoxide is used because it has a high affinity for hemoglobin. This helps medical professionals determine how well oxygen can diffuse through the lungs into the bloodstream as well. 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: Algorithm for interpreting results of spirometry.
