66 patients divided into 3 groups with different modes of ventilation.
Sixty-six patients going through open-heart surgeries were included in the study, divided into 3 groups (P: pressure controlled ventilation, V: volume controlled ventilation, C: control) in accordance with the mode of ventilation. Patients studied for chest x-ray, lung ultrasound, arterial oxygen partial pressure to fractional inspired oxygen ratio (PaO2/FiO2), Alveolar-arterial oxygen gradient, static lung compliance and dynamic lung compliance, taken after induction of anesthesia, 1h post cardiopulmonary bypass, 1h after arrival to cardiac surgical unit.
