Investigating the relationships among lung function variables in chronic obstructive pulmonary disease in men [PDF]

PeerJ, 2019
Background In patients with chronic obstructive pulmonary disease (COPD), the independent contributions of individual lung function variables to outcomes may be lower when they are modelled together if they are collinear.

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 ...

Correlation Analysis of the Lung Volume Reduction and the Lung Function Loss 
after the Thoracoscopic Lobectomy

Chinese Journal of Lung Cancer, 2022
Background and objective To investigate the correlation between the reduction of lung volume and the degree of lung function damage after lobectomy. Methods A total of 131 patients (72 males and 59 females) who underwent thoracoscopic lobectomy in the ...

Distribution of transpulmonary pressure during one-lung ventilation in pigs at different body positions

Frontiers in Physiology, 2023
Background. Global and regional transpulmonary pressure (PL) during one-lung ventilation (OLV) is poorly characterized. We hypothesized that global and regional PL and driving PL (ΔPL) increase during protective low tidal volume OLV compared to two-lung ...

Flow-Volume Parameters in COPD Related to Extended Measurements of Lung Volume, Diffusion, and Resistance

Pulmonary Medicine, 2013
Classification of COPD into different GOLD stages is based on forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) but has shown to be of limited value.

Determination of reliable lung function parameters in intubated mice

Respiratory Research, 2019
Background Animal models and, in particular, mice models, are important tools to investigate the pathogenesis of respiratory diseases and to test potential new therapeutic drugs. Lung function measurement is a key step in such investigation.

Lung volume segmentation in fetal MRI: super-resolution reconstructions improve inter-rater reliability

European Radiology Experimental
Background Fetal MRI is increasingly used to investigate fetal lung pathologies, and super-resolution (SR) algorithms could be a powerful clinical tool for this assessment.

Measuring pulmonary function in COPD using quantitative chest computed tomography analysis

European Respiratory Review, 2021
COPD is diagnosed and evaluated by pulmonary function testing (PFT). Chest computed tomography (CT) primarily serves a descriptive role for diagnosis and severity evaluation.
