Morphometric model for pulmonary diffusing capacity I. Membrane diffusing capacity
Respiration Physiology, 1993The pulmonary diffusing capacity is related to the quantitative design characteristics of the pulmonary gas exchanger. The current model for estimating DLO2 from morphometric data breaks the diffusion path for O2 into four steps, three of which represent the membrane part of DLO2.

, 2005 Transfer of oxygen and carbon dioxide over the alveolocapillary membrane is the main function of the lungs and can be measured by the diffusing capacity for carbon monoxide (CO). CO has a high affinity for hemoglobin and is absent in pulmonary capillary blood.

Standardized single breath normal values for carbon monoxide diffusing capacity.
American Review of Respiratory Disease, 2015Prediction equations for DLCO and diffusing capacity per unit of lung volume (DL/VA) were generated from 245 normal subjects (122 women and 123 men) using a standardized technique for measuring DLCO. Measurements were made at an altitude of 1,400 meters.

Carbon Monoxide Diffusing Capacity
Clinics in Chest Medicine, 1989Before measuring single-breath DLCO it is important to: (1) standardize carefully test technique and computation using current ATS guidelines; (2) confirm that computerized systems correctly perform the calculations; and (3) confirm that the reference values selected are consistent with the data produced by the device in the laboratory by comparing ...

Pulmonary diffusing capacity of athletes
Journal of Applied Physiology, 1963Champion swimmers have been found to have significantly higher steady-state pulmonary diffusing capacities than those measured in normal subjects of comparable age at the same exercise level. Nonactive and moderately active normal subjects, swimmers of average ability, long distance runners, and older ex-athletes were found to show no significant ...

A rebreathing method for estimating diffusing capacity, membrane diffusing capacity, pulmonary capillary blood volume, pulmonary capillary blood flow, and pulmonary tissue volume consists of rebreathing into a bag for 15 sec while acetylene, (18O)-carbon

The diffusing capacity for carbon monoxide (DL(CO)) is a commonly performed and clinically useful pulmonary function test that provides a quantitative measure of gas transfer in the lungs. It is valuable for evaluating and managing patients with a wide variety of pulmonary disorders, especially patients with interstitial lung disease, pulmonary ...

The Reliability of the Pulmonary Diffusing Capacity Determination
Scandinavian Journal of Clinical and Laboratory Investigation, 1962The test-retest reliability of the ten second breath-holding method for the determination of pulmonary diffusing capacity of carbon monoxide was studied in a series of 151 men and women, including patients, normal subjects and athletes.The mean and standard deviation of the DLCO was 28.2 ± 10.09 ml × min−1 × mmHg−1.

It has been previously shown that conventional methods of measuring the single-breath diffusing capacity of the lung for carbon monoxide (DLCOsb) overestimate diffusion in normal subjects when the expiratory flow rate is reduced, when the collection of ...

A simple method was developed for estimating pulmonary diffusing capacity by morphometry using light microscopic preparations of normal and diseased human lungs. It should be particularly useful in studying emphysematous lungs obtained at autopsy in view
