Breathing Rhythm Variations during Wash-In Do Not Influence Exhaled Volatile Organic Compound Profile Analyzed by an Electronic Nose

open access: yesMolecules, 2021
E-noses are innovative tools used for exhaled volatile organic compound (VOC) analysis, which have shown their potential in several diseases. Before obtaining a full validation of these instruments in clinical settings, a number of methodological issues ...

Current definitions of the breathing cycle in alveolar breath-by-breath gas exchange analysis

open access: yesAmerican Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2023
Identification of the breathing cycle forms the basis of any breath-by-breath gas exchange analysis. Classically, the breathing cycle is defined as the time interval between the beginning of two consecutive inspiration phases. Based on this definition, several research groups have developed algorithms designed to estimate the volume and rate of gas ...

Aldehydes in Exhaled Breath during E-Cigarette Vaping: Pilot Study Results

open access: yesToxics, 2018
Several studies have shown the presence of aldehydes (i.e., formaldehyde, acrolein) in mainstream emissions of some e-cigarettes. For this reason, concerns have been raised regarding potential toxicity.

Analysis of Exhaled Breath Condensate pH in Asthma among Indian Population: A Pilot Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Asthma is an inflammatory disorder of lungs and analysis of Exhaled Breath Condensate (EBC) pH may give insights on control of asthma. To the best of our knowledge, this is the first study of EBC pH among Indian population.

Metabolism Determination By Soft Computing Methods From Breath Molecules

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The breath analysis is a non-invasive risk-free and painless method used to diagnose specific diseases. Since the breath analysis method is a new study field than the other methods, there are many unsettled standards and unknown parameters.

Monotone Signal Segments Analysis as a novel method of breath detection and breath-to-breath interval analysis in rat [PDF]

open access: yesRespiratory Physiology & Neurobiology, 2008
We applied a novel approach to respiratory waveform analysis--Monotone Signal Segments Analysis (MSSA) on 6-h recordings of respiratory signals in rats. To validate MSSA as a respiratory signal analysis tool we tested it by detecting: breaths and breath-to-breath intervals; respiratory timing and volume modes; and changes in respiratory pattern caused ...

Understanding the Potential of WO3 Based Sensors for Breath Analysis

open access: yesSensors, 2016
Tungsten trioxide is the second most commonly used semiconducting metal oxide in gas sensors. Semiconducting metal oxide (SMOX)-based sensors are small, robust, inexpensive and sensitive, making them highly attractive for handheld portable medical ...

Exhaled Volatile Organic Compounds during Inflammation Induced by TNF-α in Ventilated Rats

open access: yesMetabolites, 2020
Systemic inflammation alters the composition of exhaled breath, possibly helping clinicians diagnose conditions such as sepsis. We therefore evaluated changes in exhaled breath of rats given tumor necrosis factor-alpha (TNF-α). Thirty male Sprague-Dawley
