Cardiac stabilization during “off-pump” coronary revascularization (OPCAB) has been implicated in causing intraoperative hemodynamic disturbances. Stroke volume and cardiac output reductions may alter the ventilation/perfusion ratio in the lungs and compromise the gas exchange. This study was conducted to determine the impact of heart’s stabilization on arterial blood-gas profile in patients undergoing OPCAB surgery.
