Cardiopulmonary Bypass on Mechanical Power and Postoperative Pulmonary Complications
During cardiopulmonary bypass (CPB), oxygenation of the patient on the pump can be left completely under pump control, or the lungs can be ventilated with low tidal volume to reduce atelectasis. In recent years, the concept of mechanical power has been used to determine the extent of ventilator-related lung damage. This concept of mechanical power, by which the energy transferred by the ventilator to the lungs can be calculated, will be measured at certain intervals in CPB surgery patients on the pump and compared between the two groups. The investigators aimed to investigate the effect of two different ventilation methods on mechanical power and its relationship with postoperative pulmonary complications.
