Lung stress and strain calculations in mechanically ventilated patients in the intensive care unit [PDF]

, 2016
Background Stress and strain are parameters to describe respiratory mechanics during mechanical ventilation. Calculations of stress require invasive and difficult to perform esophageal pressure measurements.

Automatic algorithm for quantifying lung involvement in patients with chronic obstructive pulmonary disease, infection with SARS-CoV-2, paracoccidioidomycosis and no lung disease patients

PLoS ONE, 2021
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.

Sleep‐Disordered Breathing, Hypoxia, and Pulmonary Physiologic Influences in Atrial Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
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 ...

Exclusion of emphysematous lung from dose-volume estimates of risk improves prediction of radiation pneumonitis

Radiation Oncology, 2017
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 ...

Comparison Between Magnetic Resonance Imaging and Computed Tomography in the Detection and Volumetric Assessment of Lung Nodules: A Prospective Study

Frontiers in Medicine, 2022
Rationale and ObjectivesComputed tomography (CT) lung nodule assessment is routinely performed and appears very promising for lung cancer screening. However, the radiation exposure through time remains a concern.

The Effect of Lung Volume on the Size and Volume of Pulmonary Subsolid Nodules on CT: Intraindividual Comparison between Total Lung Capacity and Tidal Volume

대한영상의학회지, 2021
Purpose To examine the effect of lung volume on the size and volume of pulmonary subsolid nodules (SSNs) measured on CT. Materials and Methods A total of 42 SSNs from 31 patients were included. CT examination was first performed at total lung capacity

The effect of Hugo point acupressure massage on respiratory volume and pain intensity due to deep breathing in patients with chest tube after chest surgeries

Contemporary Clinical Trials Communications, 2022
Introduction: Hugo point is the most important pain control point in the body, so the study was performed to determine the effect of Hugo point massage on respiratory volume and the pain intensity after chest tube placement.

Estimation of lung growth using computed tomography [PDF]

, 2003
Anatomical studies suggest that normal lungs grow by rapid alveolar addition until about 2 yrs of age followed by a gradual increase in alveolar dimensions.
