Bronchodilatation induced by deep breaths in relation to transpulmonary pressure and lung volume.

Bronchodilatation induced by deep breaths in relation to transpulmonary pressure and lung volume.

Induced bronchoconstriction in normal subjects can be transiently reversed by a deep breath (airway hysteresis). The mechanisms of airway hysteresis are not fully understood. The aim of these studies was to determine whether the nature of the deep breath (slow or fast inspiration, five or 10 second breath hold) affects the resultant bronchodilatation. Bronchoconstriction was induced in 10 norma...

Targeting transpulmonary pressure to prevent ventilator induced lung injury.

Acute respiratory distress syndrome (ARDS) and ventilator induced lung injury (VILI) continue to challenge clinicians who care for the critically ill. Current research in ARDS has focused on ventilator strategies to improve the outcome for these patients. In this review, we emphasize the limitations of managing ventilators based on airway pressures alone. Specifically, basic pulmonary mechanics...

Two steps forward in bedside monitoring of lung mechanics: transpulmonary pressure and lung volume

efl teachers job satisfaction and social capital in relation to students’ motivation

abstract this mixed method study examines whether there is any relationship among the variables of the study (job satisfaction, social capital and motivation). the researcher considered job satisfaction and social capital as independent variables; motivation is the dependent variable of the study. the researcher applied a questionnaire to assess each variable. to measure efl teachers’ job sati...

: examining l2 teachers’ corrective feedback types in relation to learners’ uptake, proficiency levels, and context types

abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
