ABSTRACT
Objective To investigate the effects of low tidal volume ventilation on pulmonary and cardiac function before and after mitral valve replacement. Methods Thirty patients with mitral valve diseases were randomly divided into traditional tidal volume ventilation (groupⅠ), low tidal volume ventilation with conventional respiratory rate (group Ⅱ), and low tidal volume ventilation with high respiratory rate (group Ⅲ). Mean arterial pressure (MAP), cardiac output(CO), cardiac index(CI), mean pulmonary arterial pressure (MPAP), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), systemic vascular resistance index (SVRI), and pulmonary vascular resistance index (PVRI) were monitored. Arterial oxygen tension (PaO_2), carbon dioxide tension (PaCO_2), oxygen saturation index(PaO_2/FiO_2), alveolar-arterial PO_2 gradient (PA-aO_2), and Q_S/Q_T were measured. Results Before CPB, CO in group Ⅰ was significantly lower than that in group Ⅲ (P
