ABSTRACT

Introduction: positive pressure ventilation is used in multiple cardiac pathologies as a life support measure to achieve adequate gas exchange and improve tissue perfusion. The operator must be aware of the pathophysiological interactions of the critically ill patient in order to be able to discern when the use of mechanical ventilation is appropriate, or its use could be deleterious. A programming of parameters not in accordance with the patient's needs could cause pulmonary damage and hemodynamic deterioration. Not understanding cardiopulmonary interactions in mechanical ventilation will change the prognosis of any patient for the worse. In congenital heart disease with communication between pulmonary and systemic circulation, this management can increase pulmonary vascular resistance, with the appearance or worsening of an intracardiac shunt that can have important consequence. Case report: patient with congenital heart disease who after ventilatory management worsened hemodynamically to a state of refractory shock with persistent desaturation, improving with lower airway pressures and early extubation. Reports of cases with the same evolution are mentioned. Conclusion: understanding cardiopulmonary interactions improves the prognosis of patients on mechanical ventilation.
