Ventilation in right ventricular dysfunction

Description

Knowledge about the role of the right ventricle in health and disease historically has lagged behind that of the left ventricle. Consequently, comparatively little attention has been devoted to how right ventricular dysfunction. The hemodynamic consequences of mechanical ventilation are easy to understand by examining the impact upon the right ventricle of applying a positive airway pressure. On the one hand, cyclic (tidal ventilation) or continuous (PEEP application) changes in transpulmonary pressure produced by respiratory support directly affect RV outflow impedance. On the other hand, cyclic(tidal ventilation) or continuous (PEEP application) increase in pleural pressure produced by respiratory support increases RV effective elastance, a factor limiting diastolic filling. In this presentation we will highlight the effect of ventilation in right ventricle and what can be done with ventilatory parameters to manage  right ventricular dysfunction.
