Smokers are assessed for chronic obstructive pulmonary disease (COPD) using spirometry, with COPD defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) as airflow limitation that is not fully reversible with bronchodilators. There is a subset of smokers with normal spirometry (by GOLD criteria), who have a low diffusing capacity of the lung for carbon monoxide ( D LCO

Functional residual capacity (FRC) cannot be measured via spirometry, but it can be measured with a plethysmograph or dilution tests (for example, helium dilution test). Average values for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced expiratory flow 25–75% (FEF25–75%), according to a study in the

Data collection was performed with a Collins CPL system. Each subject was instructed to perform at least two diffusing capacity maneuvers. Diffusing capacity of the lung (D L) (also known as Transfer factor is another expression for the formerly used diffusing capacity.) measures the transfer of gas from air in the lung, to the red blood cells in lung blood vessels. It is part of a comprehensive series of pulmonary function tests to determine the overall ability of the lung to transport gas into and out of the blood.

Pulmonary function was evaluated with spirometry, diffusing capacity and radio spirometry. Her er det for utsatt 0-vind, og for hold hvor innslag av helikopter.

Spirometry can also help to assess if treatment (for example inhalers) opens up the airways. The spirometry readings will improve if the narrowed airways become wider after medication. This is called reversibility (see later for more details). Generally, asthma has more of a reversible element to the airways obstruction, compared with COPD. So, the diffusing capacity for nitric oxide (D LNO) reflects more of an alveolar–capillary membrane diffusion, whereas D LCOc is largely represented by V cap rather than the membrane diffusion . Both gases combined yield the D LNO / D LCOc ratio which sheds light on the possible causes of diffusion impairment [ 5 ].
