[Evaluation of low flow anesthesia, comparing pressure-controlled ventilation to time-cycled pressure-limited continuous flow ventilation: experimental model in rabbits.].

Background And Objectives: Despite the well-known advantages of rebreathing systems and low flow anesthesia, they are seldom used in small animals and pediatric anesthesia. The experimental model of this study was designed to evaluate a rebreathing system with flows between 500 to 1,000 ml.min-1 in small animals, in addition to comparing time-controlled pressure-limited and constant gas flow ventilation to pressure-controlled ventilation in a new anesthesia machine.
