Question

Mechanical ventilator may lead to cardiovascular compromising?

Answer 1

Mechanical ventilation always has some effect on the cardiovascular system. Positive-pressure ventilation can decrease preload, stroke volume, and cardiac output. Positive-pressure ventilation also affects renal blood flow and function, resulting in gradual fluid retention. The incidence of stress ulcers and sedation-related ileus is increased when patients receive mechanical ventilation. In fact, mechanical ventilation is a primary indication for GI prophylaxis. Positive pressure maintained in the chest may decrease venous return from the head, increasing intracranial pressure and worsening agitation, delirium, and sleep deprivation.

It is easy to underestimate the effects of ventilation on the cardiovascular system, or to misinterpret cardiopulmonary interactions as primary cardiovascular events.simple ventilatory interventions can sometimes be used to obviate the unnecessary escalation of pharmacological support, and anticipatory management with fluids or vasoactive agents can minimise cardiovascular compromise during mechanical ventilation. Mechanical ventilation plays a crucial role in the haemodynamic management of critically ill children.
