Supine posture changes lung volumes and increases ventilation heterogeneity in cystic fibrosis. [PDF]

PLoS ONE, 2017
Lung Clearance Index (LCI) is recognised as an early marker of cystic fibrosis (CF) lung disease. The effect of posture on LCI however is important when considering longitudinal measurements from infancy and when comparing LCI to imaging studies.35 ...

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 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.

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

Respiratory Function in Healthy Taiwanese Infants: Tidal Breathing Analysis, Passive Mechanics, and Tidal Forced Expiration. [PDF]

PLoS ONE, 2015
Although infant lung function (ILF) testing is widely practiced in developed Western countries it is not typically performed in Eastern countries, and lung measurements are scarce for Asian infants.

Lung volumes and airway resistance in patients with a possible restrictive pattern on spirometry

Jornal Brasileiro de Pneumologia
Objective: Many patients with proportional reductions in FVC and FEV1 on spirometry show no reduction in TLC. The aim of this study was to evaluate the role that measuring lung volumes and airway resistance plays in the correct classification of patients
