Comparison of two diffusing capacity methods - a pilot study

PROJEKT MED STÖD FRÅN VETENSKAPSRÅDET - MTF

The implications of a low DLCO are well-recognized, but the clinical significance of a high DLCO is not clear. Pulmonary diffusing capacity is often measured by D iffusion capacity of the L ungs for carbon monoxide (DLCO).In essence, this measures how much CO can pass from the alveoli to the blood in the pulmonary capillaries, thus giving clinicians the broader idea of how much inhaled gas can pass into the blood through the lungs. the volume of blood in the pulmonary capillaries available to bind carbon monoxide. The lower the volume, the lower the diffusion capacity. While interstitial lung diseases thicken the alveolar capillary-membrane, thickening of the membrane is not the major factor behind the observed reduction in diffusion capacity. Methods: We performed a retrospective review of pulmonary function tests in subjects ≥40 y old (mean age 64.6 y), including pre-bronchodilator measures for: 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).

A 29-year study published in Chest concluded that lung capacity is a long-term predictor of respiratory mortality, and should be used as a tool for general health assessment. Because of this, people with chronic pulmonary conditions should pay particular care to DLCO, also known as the TLCO, is a measurement of the conductance or ease of transfer for CO molecules from alveolar gas to the hemoglobin of the red blood cells in the pulmonary circulation. BACKGROUND: The lung diffusion capacity (D LCO) determined by the single-breath technique greatly helps in the differential diagnosis and classification of severity of common lung diseases. However, widespread use of single-breath D LCO tests in Latin America has been limited, in part, by the lack of appropriate reference values. Diffusion Capacity is another type of pulmonary function test. It is a measure of the way in which gas exchanges across your lungs. It takes longer to perform this test than spirometry.

Int J 2018-05-17 · A lung diffusion test is used to examine how your lungs are processing air. Along with other tests, it can help your doctor determine whether your respiratory system is working properly and Regardless of the mechanism by which pulmonary diffusion capacity increases, there is little research exploring how different types of training influence DL NO. As such, the purpose of the present study was to investigate the effect of high‐intensity interval training on lung function, specifically DL NO, in a group of relatively sedentary women.

Other names for this particular test are lung diffusion testing or diffusing capacity of the lung for carbon monoxide (DLCO). Pulmonary volume is the amount of air a person inhales and exhales. Pulmonary capacity is the sum of two or more primary lung volumes.

Lung diffusing capacity for NO (DLNO) and the alveolar-capillary membrane diffusing capacity (D m) decreases over time (both p = 0.01). Lung capillary blood volume (V c) tends to increase over time (p = 0.07).
