Physical Properties of Helium and Application in Respiratory Care

Encyclopedia, 2023
Helium is a low-density, inert, monoatomic gas that is widely used in medical applications. In respiratory care, Helium is mainly used as an adjunct therapy for patients with severe upper airway obstruction and asthma.

The Bidirectional Relationship Between Obstructive Sleep Apnea and Metabolic Disease [PDF]

, 2018
Obstructive sleep apnea (OSA) is a common sleep disorder, effecting 17% of the total population and 40–70% of the obese population (1, 2). Multiple studies have identified OSA as a critical risk factor for the development of obesity, diabetes, and ...

Evaluating the effects of vitamin D Level on airway obstruction in two asthma endotypes in humans and in two mouse models with different intake of vitamin D during early-life

Frontiers in Immunology, 2023
IntroductionAsthma is primarily divided into two categories: type 2 (T2-high) and non-type 2 (T2-low). A relationship between asthma severity and vitamin D deficiency has been identified, but its impact on each asthma endotype remains unknown.MethodsWe ...

Impulse oscillometry may be of value in detecting early effects of obesity on airway resistance

Egyptian Journal of Chest Disease and Tuberculosis, 2019
Background and objective Obesity as a major nutritional problem is badly associated with respiratory compliance. The effortless technique such as impulse oscillometry system (IOS) could have a supremacy value over the commonly used pulmonary function ...

A novel approach in understanding the basic modes of ventilation in a recent generation mechanical ventilator– A review of the underlying principles

Indian Journal of Anaesthesia, 2023
Understanding the basic concepts and the dynamics of the equation of motion will help the anaesthesiologist and the intensive care physician in gaining an insight into the basics of modern mechanical ventilation. An equation of the type Vt = V0 × (1-e-kt)

The regulation of host defences to infection by the microbiota [PDF]

, 2016
The skin and mucosal epithelia of humans and other mammals are permanently colonised by large microbial communities (the microbiota). Due to this life-long association with the microbiota, these microbes have an extensive influence over the physiology of

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.

Randomized crossover comparison of proportional assist ventilation and patient-triggered ventilation in extremely low birth weight infants with evolving chronic lung disease [PDF]

, 2007
Background: Refinement of ventilatory techniques remains a challenge given the persistence of chronic lung disease of preterm infants. Objective: To test the hypothesis that proportional assist ventilation ( PAV) will allow to lower the ventilator ...

Assessment of functional tests on determining resistance of respiratory tract in patients with bronchial asthma, COPD and their combination.

Medičnì Perspektivi, 2017
The mechanical properties of the respiratory tract (including airway resistance) is an important indicator of pulmonary function, and definition of resistance is used to diagnose and monitor obstructive lung diseases. This study was performed in order to

Guanylyl cyclase activation reverses resistive breathing–induced lung injury and inflammation [PDF]

, 2015
Inspiratory resistive breathing (RB), encountered in obstructive lung diseases, induces lung injury. The soluble guanylyl cyclase (sGC)/cyclic guanosine monophosphate (cGMP) pathway is down-regulated in chronic and acute animal models of RB, such as ...
