Methods of airway resistance assessment.
Pneumonologia i Alergologia Polska, 2016 Airway resistance is the ratio of driving pressure to the rate of the airflow in the airways. The most frequent methods used to measure airway resistance are whole-body plethysmography, the interrupter technique and the forced oscillation technique.

Cholesterol-sensing liver X receptors stimulate Th2-driven allergic eosinophilic asthma in mice [PDF]
, 2016 Introduction: Liver X receptors (LXRs) are nuclear receptors that function as cholesterol sensors and regulate cholesterol homeostasis. High cholesterol has been recognized as a risk factor in asthma; however, the mechanism of this linkage is not known.

Exercise-Induced Bronchoconstriction Identified Using the Forced Oscillation Technique
Frontiers in Physiology, 2019 Objective: Lung mechanics using the forced oscillation technique (FOT) is suggested to be equivalent and more sensitive in determining exercise-induced bronchoconstriction (EIB) than spirometry.

Spirometry-based airways disease simulation and recognition using Machine Learning approaches [PDF]
LION15 - Learning and Intelligent Optimization Conference, Jun
2021, Athens, Greece, 2021 The purpose of this study is to provide means to physicians for automated and fast recognition of airways diseases. In this work, we mainly focus on measures that can be easily recorded using a spirometer. The signals used in this framework are simulated using the linear bi-compartment model of the lungs.

Estimating Airway Resistance from Forced Expiration in Spirometry
Applied Sciences, 2019 Spirometry is the gold standard to detect airflow limitation, but it does not measure airway resistance, which is one of the physiological factors behind airflow limitation. In this study, we describe the dynamics of forced expiration in spirometry using

Impact of Airways Geometry on Transport of Gases to Blood [PDF]
arXiv, 2021 Topological structure of bronchial trees affects transport of gases and aerosols in the respiratory system. We start by providing a quantitative assessment of the ability of the alternative tree representations to predict observable geometric and mechanistic characteristics, such as network resistance, dead space volume, and path length.

Physiopathological rationale of using high-flow nasal therapy in the acute and chronic setting: A narrative review [PDF]
, 2019 Chronic lung disease and admissions due to acute respiratory failure (ARF) are becoming increasingly common. Consequently, there is a growing focus on optimizing respiratory support, particularly non-invasive respiratory support, to manage these ...

A Systems Engineering Approach to Modeling and Analysis of Chronic Obstructive Pulmonary Disease (COPD) [PDF]
arXiv, 2022 Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease characterized by airflow limitation. This study develops a systems engineering framework for representing important mechanistic details of COPD in a model of the cardio-respiratory system.
