Methods for Measuring Lung Volumes: Is There a Better One? [PDF]
<b><i>Background:</i></b> Accurate measurement of lung volumes is of paramount importance to establish the presence of ventilatory defects and give insights for diagnostic and/or therapeutic purposes. <b><i>Objectives:</i></b> It was the aim of this study to measure lung volumes in subjects with ...

Measurement and Analysis of Lobar Lung Deformation After a Change of Patient Position During Video-Assisted Thoracoscopic Surgery [PDF]
Video-assisted thoracoscopic surgery (VATS) is a minimally invasive surgical technique for the diagnosis and treatment of early-stage lung cancer. During VATS, large lung deformation occurs as a result of a change of patient position and a pneumothorax (lung deflation), which hinders the intraoperative localization of pulmonary nodules.

Quantitative computerized tomography evaluation of the effects of COVID-19 pneumonia on lung volume
Purpose: The aim of this study was o assess the relationship between lung volume decrease and computed tomography (CT) findings in patients with COVID-19 pneumonia in early period.

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

Elastocapillary network model of inhalation [PDF]
The seemingly simple process of inhalation relies on a complex interplay between muscular contraction in the thorax, elasto-capillary interactions in individual lung branches, propagation of air between different connected branches, and overall air flow into the lungs.

In this work, we aimed to develop an automatic algorithm for the quantification of total volume and lung impairments in four different diseases. The quantification was completely automatic based upon high resolution computed tomography exams.

An apparatus for the measurement of lung volume and compliance in mice [PDF]
Pressure-volume (P-V) curves and total lung capacity (TLC) were measured in excised lung of mice using a water manometer and a closed system in which the humidity and temperature were controlled. In pathogen-free mice there are no significant differences in elastic properties of these lungs in relation to their age.

Background The risk factors for radiation pneumonitis (RP) in patients with chronic obstructive pulmonary disease (COPD) are unclear. Mean lung dose (MLD) and percentage of irradiated lung volume are common predictors of RP, but the most accurate ...

Sleep‐Disordered Breathing, Hypoxia, and Pulmonary Physiologic Influences in Atrial Fibrillation
Background We leverage a large clinical cohort to elucidate sleep‐disordered breathing and sleep‐related hypoxia in incident atrial fibrillation (AF) development given the yet unclear contributions of sleep‐related hypoxia and pulmonary physiology in ...

Extracting lung function-correlated information from CT-encoded static textures [PDF]
The inherent characteristics of lung tissues, which are independent of breathing manoeuvre, may provide fundamental information on lung function. This paper attempted to study function-correlated lung textures and their spatial distribution from CT.
