The Effect of Mechanical Ventilation on the Occurrence of Myocardial Ischemia: a Pilot Study

Ventilation is continued from going on CPB until clamping of the ascending aorta with tidal volume 3ml/kg ideal body weight, Fraction of inspired oxygen (FiO2) 50%, respiratory rate 5/min and Inspiratory:Expiratory (I/E) ratio 1/2.

Ventilation is discontinued after going on CPB and lungs are exposed to atmospheric pressure
