Continuous low tidal volume ventilation during cardiopulmonary bypass reduces the risk of pulmonary dysfunction

ABSTRACT

Objective: Pulmonary dysfunction is considered to be the most important complication after open heart surgery. Different maneuvers like intermittent or continuous positive pressure ventilation, low tidal volume ventilation and different vital capacity maneuvers have been used for reducing the incidence of pulmonary dysfunction after cardiac surgery. In this study we evaluated the effects of low tidal volume ventilation versus no-ventilation during cardiopulmonary bypass [CPB] in patients undergoing conventional CABG surgery
