Comparison of Forced Oscillometric Technique and Spirometry in Stable Asthmatic Patients in Central India: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research, 2023
Introduction: Asthma is an airway disease, the diagnosis of this disease still continues to be a clinical based. Although, there are several tests that can be useful for asthma, but no one can be considered as a standard test and search for better ...

Clinical applications of the respiratory equation of motion to guide decision-making in the patient under invasive mechanical ventilation

Iatreia, 2023
Introduction: Mechanical ventilation is a common practice in intensive care units and anesthesiology with both therapeutic and potentially harmful implications for the respiratory system and distant organs, that is why it is of utmost importance to ...

Correlation Analysis between Airway Volume and Risk of Sleep Apnea/Periodontitis

eJournal of Oral Maxillofacial Research, 2022
Objectives: Sleep apnea and periodontitis have high incidences in general population. They share common risk factors such as obesity, smoking, and aging. As cone-beam computed tomography becomes popular in dentistry, airway analysis is very accessible to

Plethysmographic Loops: A Window on the Lung Pathophysiology of COPD Patients

Frontiers in Physiology, 2018
Plethysmographic alveolar pressure-flow (Palv–F) loops contain potentially relevant information about the pathophysiology of chronic obstructive pulmonary disease (COPD), but no quantitative analysis of these loops during spontaneous breathing has ever ...

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.

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)

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.

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
