[HTML][HTML] Lung volume dependence of respiratory function in rodent models of diabetes mellitus
Background Diabetes mellitus causes the deterioration of smooth muscle cells and interstitial
matrix proteins, including collagen. Collagen and smooth muscle cells are abundant in the …

Capnogram slope and ventilation dead space parameters: comparison of mainstream and sidestream techniques
Background Capnography may provide useful non-invasive bedside information concerning
heterogeneity in lung ventilation, ventilation–perfusion mismatching and metabolic status. …

Different contributions from lungs and chest wall to respiratory mechanics in mice, rats, and rabbits
…, Á Schranc, J Tolnai… - Journal of applied …, 2019 - journals.physiology.org
Changes in lung mechanics are frequently inferred from intact-chest measures of total
respiratory system mechanics without consideration of the chest wall contribution. The …

Size distribution of recruited alveolar volumes in airway reopening
In 11 isolated dog lung lobes, we studied the size distribution of recruited alveolar volumes
that become available for gas exchange during inflation from the collapsed state. Three …

Scaling behavior in crackle sound during lung inflation
During slow inflation of lung lobes, we measure a sequence of short explosive transient
sound waves called “crackles,” each consisting of an initial spike followed by ringing. The …

Acoustic evidence of airway opening during recruitment in excised dog lungs
The aim of this study was to test the hypothesis that the mechanism of recruitment and the
lower knee of the pressure-volume curve in the normal lung are primarily determined by …

[HTML][HTML] Volumetric but not time capnography detects ventilation/perfusion mismatch in injured rabbit lung
Whereas time capnography (Tcap) is routinely displayed during mechanical ventilation, the
volumetric representation (Vcap) is seldom used. We compared the diagnostic value of …

Functional and morphological assessment of early impairment of airway function in a rat model of emphysema
J Tolnai, MV Szabari, G Albu, BA Maár… - Journal of Applied …, 2012 - journals.physiology.org
The aim of this study was to evaluate airway structure-function relations in elastase-induced
emphysema in rats. Sprague-Dawley rats were treated intratracheally with 50 IU porcine …

[HTML][HTML] Exaggerated ventilator-induced lung injury in an animal model of type 2 diabetes mellitus: A randomized experimental study
Although ventilator-induced lung injury (VILI) often develops after prolonged mechanical
ventilation in normal lungs, pulmonary disorders may aggravate the development of adverse …
