Respiratory Volumes in Labour

Lung Volumes and Capacities in Respiratory Diseases

Introduction The basic 4 volumes do not overlap each other: tidal volume, inspiratory and expiratory reserve volumes and residual volume. On the other hand, lung capacities include two or more volumes: inspiratory capacity, vital capacity, functional residual capacity and total lung capacity. Spirographic examination of lung functions is characterized by the following main changes: in the obstr...

Respiratory motion estimation of multi-modal CT/MRI lung volumes

Measurement of the respiratory volumes of laboratory animals.

In the last few years a tremendous amount of study has been directed toward the etiology and pathogenesis of respiratory disease. Quantitative studies of respiratory infection by t.he cloud chamber method require that the respiratory volume of test. animals be known in order to calcu late the dose of agent used. Because data in the literature on respiratory volume of laboratory animals are very...

Lung volumes and respiratory mechanics in elastase-induced emphysema in mice.

Absolute lung volumes such as functional residual capacity, residual volume (RV), and total lung capacity (TLC) are used to characterize emphysema in patients, whereas in animal models of emphysema, the mechanical parameters are invariably obtained as a function of transrespiratory pressure (Prs). The aim of the present study was to establish a link between the mechanical parameters including t...

Lower tidal volumes in Brazil, also in patients without acute respiratory distress syndrome?

volumes (V T ) to be low in patients in Brazilian ICUs. By showing this, it is clear that ventilation practice in Brazil mirrors worldwide changes, at least with regard to V T in patients with acute respiratory distress syndrome (ARDS) [2,3]. Eff orts to implement protective ventilation have been largely restricted to patients with ARDS, which is understandable since its benefi cial eff ects we...
