Measurement of the Pressure-volume Curve in Mouse Lungs [PDF]
Journal of Visualized Experiments, 2015 In recent decades the mouse has become the primary animal model of a variety of lung diseases. In models of emphysema or fibrosis, the essential phenotypic changes are best assessed by measurement of the changes in lung elasticity. To best understand specific mechanisms underlying such pathologies in mice, it is essential to make functional ...

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.
