Characterisation of Brachycephalic Obstructive Airway Syndrome in French Bulldogs Using Whole-Body Barometric Plethysmography. [PDF]

PLoS ONE, 2015
Brachycephalic obstructive airway syndrome (BOAS) is an important health and welfare problem in several popular dog breeds. Whole-body barometric plethysmography (WBBP) is a non-invasive method that allows safe and repeated quantitative measurements of ...

Sevoflurane and Hypercapnia Blunt the Physiological Variability of Spontaneous Breathing: A Comparative Interventional Study

Frontiers in Physiology, 2022
Background: Although spontaneous breathing is known to exhibit substantial physiological fluctuation that contributes to alveolar recruitment, changes in the variability of the respiratory pattern following inhalation of carbon dioxide (CO2) and volatile

Determination of Ventilatory Volume in Mice by Whole Body Plethysmography.

The Japanese Journal of Physiology, 1997
We examined the reliability of whole-body plethysmography (WBP) for determining the ventilatory volume in mice. The degree of agreement of tidal volume (VT) determined consecutively by WBP with that by direct plethysmography (DP) or pneumotachography (PT) was analyzed using urethane-anesthetized young male 129/Sv mice.

The abdominal circulatory pump. [PDF]

PLoS ONE, 2009
Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body ...

Positive correlation of airway resistance and serum asymmetric dimethylarginine (ADMA) in bronchial asthma patients lacking evidence for systemic inflammation

Allergy, Asthma & Clinical Immunology, 2018
Background Contribution of nitric-oxide (NO) pathway to the pathogenesis of bronchial asthma (asthma) is ambiguous as NO may confer both protective and detrimental effects depending on the NO synthase (NOS) isoforms, tissue compartments and underlying ...
