Pediatric Pulmonology 41:1095–1102 (2006) Comparison of Carbon Monoxide (CO) Single Breath Pulmonary Diffusing Capacity With Non-Rebreathing, Open-Circuit CO Pulmonary Diffusing Capacity in Healthy Children Oscar E. Suman, PhD,1,2* Suchmor Thomas, MD,1,2 Kenneth C. Beck, PhD,3 Ronald P. Mlcak,4 and David N. Herndon, MD1,2 Summary.

We conducted a prospective study to evaluate whether lack of an adequate increase in diffusing capacity for carbon monoxide. (DLCO) during exercise is 

Diffusing capacity of the lung for carbon monoxide (DLCO) is currently considered one of the most important risk factors for postoperative complications after lung cancer surgery . For that reason, it is mandatory to measure it during the preoperative workout of any patient in need of an anatomical lung resection [ 1 ]. Using three conventional methods and a new method we measured the single-breath diffusing capacity for carbon monoxide [DLCO(SB)] in a group of normal subjects. Whereas the conventional methods calculated DLCO(SB) from a single equation valid only for breath holding, the new method used three equations, one for each phase of the single-breath maneuver, i.e., inhalation, breath holding, and 2014-12-16 · Rationale The diffusing capacity (DL) of the lung can be divided into two components: the diffusing capacity of the alveolar membrane (Dm) and the pulmonary capillary volume (Vc). DL is traditionally measured using a single-breath method, involving inhalation of carbon monoxide, and a breath hold of 8–10 seconds (DL,CO).

The single-breath carbon monoxide diffusing capacity (DL (CO)) is the product of two measurements during breath holding at full inflation: (1) the rate constant for carbon monoxide uptake from alveolar gas (kco [minute (-1)]) and (2) the "accessible" alveolar volume (Va). kco expressed per mm Hg alveolar dry gas pressure (Pb*) as kco/Pb*, and then multiplied by Va, equals Dl (CO); thus, Dl (CO) divided by Va (DL (CO)/Va, also called Kco) is only kco/Pb* in different units, remaining,

Stam}, year={1995} } The single-breath carbon monoxide diffusing capacity (DL(CO)) is the product of two measurements during breath holding at full inflation: (1) the rate constant for carbon monoxide uptake from Thus the combined diffusing capacity for NO and CO may play a future role for the non-invasive, functional assessment of structural alterations of the lung in CF. Due to large-scale destruction, changes in membrane diffusion (Dm) may occur in cystic fibrosis (CF), in correspondence to alterations observed by computed tomography (CT). Diffusion capacity assesses how well a tracer gas in inspired air can cross from the air into the blood. The test measures the absorption of a low concentration of carbon monoxide in inhaled air by hemoglobin in red blood cells that circulate through pulmonary capillaries. Using three conventional methods and a new method we measured the single-breath diffusing capacity for carbon monoxide [DLCO(SB)] in a group of normal subjects.
