Preoperative Assessment of the Impact of Positive Pressure Ventilation With Noninvasive Positive Pressure Ventilation in a Patient With Eisenmenger Syndrome: A Case Study.

In Eisenmenger syndrome (ES), positive pressure ventilation (PPV) during general anesthesia may lead to an increase in pulmonary vascular resistance and potentially to hypoxemia. In an attempt to predict the patient's hemodynamic response to intraoperative ventilation, we tested preoperatively the hemodynamic effects of noninvasive PPV with continuous positive pressure in a woman with ES scheduled for oophorectomy. The surgery was performed without complications, and the patient was discharged on postoperative day 8.
