Prediction equations for diffusing capacity (transfer factor) of lung for North Indians

Reference values for lung function tests. III. Carbon monoxide diffusing capacity (transfer factor).

Carbon monoxide diffusing capacity (DLCO) or transfer factor (TLCO) is a particularly useful test of the appropriateness of gas exchange across the lung alveolocapillary membrane. With the purpose of establishing predictive equations for DLCO using a non-smoking sample of the adult Brazilian population, we prospectively evaluated 100 subjects (50 males and 50 females aged 20 to 80 years), rando...

Development of Prediction Equation of Diffusing Capacity of Lung for Koreans

BACKGROUND The diffusing capacity of the lung is influenced by multiple factors such as age, sex, height, weight, ethnicity and smoking status. Although a prediction equation for the diffusing capacity of Korea was proposed in the mid-1980s, this equation is not used currently. The aim of this study was to develop a new prediction equation for the diffusing capacity for Koreans. METHODS Using...

Importance of appropriately adjusting diffusing capacity of the lung for carbon monoxide and diffusing capacity of the lung for carbon monoxide/alveolar volume ratio for lung volume.

In their report on cardiac sarcoidosis, Smedema et al (July 2005)1 remarkably conclude that patients without cardiac symptoms do not require more sensitive studies to detect heart disease. This report, while of interest, is limited by a patient follow-up that varied widely from 3 to 54 months. Since this study does not well characterize the natural history of asymptomatic cardiac sarcoidosis an...
