DOI: 10.1002/ppul.23890
Abstract: Methacholine Challenge Test (MCT) is used to confirm, assess the severity and/or rule out asthma. Two MCT methods are described as equivalent by the American Thoracic Society (ATS), the tidal breathing and the dosimeter methods.… read more here.

DOI: 10.1007/5584_2018_166
Abstract: There is an interest in assessing changes in nasal NO (nNO) levels as an effect marker of upper airways. In this study, we examined methodologic influences on short and long term repeatability of nNO levels… read more here.

DOI: 10.1007/s11325-017-1588-0
Abstract: BackgroundHuman snores are caused by vibrating anatomical structures in the upper airway. The glottis is a highly variable structure and a critical organ regulating inhaled flows. However, the effects of the glottis motion on airflow… read more here.

DOI: 10.1088/1361-6560/aaff7b
Abstract: We previously reported that apparent lung mass varies across the phases of 4D computed tomography (4DCT) images. We hypothesize that these variations correspond to the physiologic changes in pulmonary perfusion induced during normal tidal breathing,… read more here.

DOI: 10.1111/coa.13653
Abstract: Awake nasopharyngoscopy is routinely performed in the assessment of patients who require treatment for sleep‐disordered breathing (SDB). However, the applicability and accuracy of Müller's manoeuvre, the main evaluation method for this purpose, are disputable. The… read more here.

DOI: 10.1152/japplphysiol.01007.2018
Abstract: Overnight analysis of tidal breathing flow volume (TBFV) loops, recorded by impedance pneumography (IP), has been successfully applied in the home monitoring of children with wheezing disorders. However, little is known on how sleep physiology… read more here.

DOI: 10.1183/1393003.congress-2017.pa3013
Abstract: Background: Ambulatory capnometers can be relatively unreliable due to condensation from breath. The development of a new ambulatory capnometer (N-Tidal) brings advantages through a novel optical system that also increases accuracy over the range of… read more here.

DOI: 10.1186/s12938-020-00777-0
Abstract: Background and objective Lung mechanics measurements provide clinically useful information about disease progression and lung health. Currently, there are no commonly practiced methods to non-invasively measure both resistive and elastic lung mechanics during tidal breathing,… read more here.

Measuring Ventilatory Activity with Structured Light Plethysmography (SLP) Reduces Instrumental Observer Effect and Preserves Tidal Breathing Variability in Healthy and COPD
Sign Up to like & getrecommendations! Published in 2017 at "Frontiers in Physiology"
DOI: 10.3389/fphys.2017.00316
Abstract: The use of a mouthpiece to measure ventilatory flow with a pneumotachograph (PNT) introduces a major perturbation to breathing (“instrumental/observer effect”) and suffices to modify the respiratory behavior. Structured light plethysmography (SLP) is a non-contact… read more here.
