Cardiovascular effects of mechanical ventilation

Abstract

It is easy to underestimate the effects of ventilation on the cardiovascular system, or to misinterpret cardiopulmonary interactions as primary cardiovascular events. We have described how simple ventilatory interventions can sometimes be used to obviate the unnecessary escalation of pharmacological support, and have discussed how in other situations, anticipatory management with fluids or vasoactive agents can minimise cardiovascular compromise during mechanical ventilation. Mechanical ventilation playsa crucial role in the haemodynamic management of critically ill children, and application of the principles that have been described are an essential part of intensive care management.
