Evaluation of air-displacement plethysmography in children aged 5-7 years using a three-component model of body composition [PDF]

, 2003
The aim of the present study was to evaluate air-displacement plethysmography (ADP) in children aged 5-7 years. Body-composition measurements were obtained by ADP, H-2 dilution and anthropometry in twenty-eight children. Calculation of body volume by ADP

Air Trapping and the Risk of COPD Exacerbation: Analysis From Prospective KOCOSS Cohort

Frontiers in Medicine, 2022
Background and AimsAir trapping is a predictive index for a decline in lung function and mortality in patients with chronic obstructive pulmonary disease (COPD). However, the role of air trapping in COPD exacerbation has rarely been studied.
