A comparative study of the ventilatory responses of the golden hamster, Mesocricetus auratus and the laboratory rat, Rattus norvegicus, under hypercapnic and/or hypoxic gas mixtures
… the white rat (<i>Rattus norvegicus</i>). Total body plethysmography was used to measure tidal volume (V<sub>T</sub>), respiratory frequency (R<sub>f</sub>), and minute volume (V<sub>E</sub>). The respiratory gases had carbon dioxide concentrations ranging from 0 to 790 and oxygen content ranging …

Acute hypoxia-induced diaphragm dysfunction is prevented by antioxidant pre-treatment
… exposure. Ventilation was assessed using whole-body plethysmography. O2 consumption and CO2 production were measured as indices of metabolism. Diaphragm muscle contractile performance was determined ex-vivo. Gene expression was examined at 1, 4, and 8 hrs using qRT-PCR. Protein/phosphoprotein …

Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption
… COPD) and examined with spirometry, body plethysmography, diffusing capacity for CO (DL,CO), IOS and ultrasonography of the internal carotid artery. They also answered questionnaires and blood samples were collected. The results show differences in DL,CO, residual volume and …

Sensory-Mechanical Responses to High-Dose Methacholine Bronchoprovocation: The Modulating Effects of Deep Inspirations
… On visit 1, after baseline spirometry and body plethysmography, participants were randomized to perform either: (i) modified high-dose MCh challenge using partial and maximal expiratory flow-volume curves (PEFV/MEFV) and impulse oscillometry (IOS) or (ii) traditional high-dose MCh challenge …

Investigating Central Chemoreception-based Biomarkers of Sudden Unexpected Death in Epilepsy (SUDEP)
… hypoxia as they approached SUDEP. Using whole-body plethysmography, we found that high-risk KO mice had elevated ventilatory chemoresponses to a mild HH challenge (mimicking transient apnea) while 71% of KO mice failed to survive a severe HH challenge (mimicking terminal apnea). We next …

Cellular Ensembles in Alveolar Homeostasis and Repair
… and physiological levels, as assessed by whole body plethysmography. Single-cell sequencing identified the epithelial and mesenchymal cell identities involved in regenerative processes, as well as identification of a PDGFA signaling axis between AT1s and resident alveolar fibroblasts necessary …

Sleep/wakefulness versus urethane anesthesia: analogous arousal states for respiratory control?
… also measured under these conditions using whole-body plethysmography in unanesthetized animals, and using a face mask and pneumotachograph in the anesthetized animals. Golden-mantled ground squirrels spent approximately 33% of the time in wakefulness(W), 31% to 14% in light sleep (LS) and 32% to …

Development of machine learning algorithms for screening of pulmonary disease
… tools included spirometry, impulse oscillometry, body plethysmography, and lung gas diffusion (DLCO). We first explored a multi-layer classification structure. Using this structure, the PFT machines produced good results on each classification layer: Healthy vs. Unhealthy [AUC=0.90 (0.04)], …
