Comparative Study between Different Modes of Ventilation during Cardiopulmonary Bypass and its Effect on Postoperative Pulmonary Dysfunction.

Background: Postoperative pulmonary dysfunction is a prevalent complication after cardiac surgery; it has many contributing considerations due to either the surgery itself, anomalies to gas exchange or maybe as a result of alterations in lung mechanics. The aim of this study was to compare pressure-controlled ventilation versus volume-controlled ventilation in the presence of no ventilation group as a control group during cardiopulmonary bypass and its effect on postoperative pulmonary dysfunction.

Patients And Methods: Sixty-six patients going through open-heart surgeries were included in the study.
