To compare the effectiveness of closed system suctioning (CSS) and open system suctioning (OSS) and the side effects on gas exchange and haemodynamics, during pressure-controlled ventilation (PCV) or continuous positive airway pressure (CPAP). Bench test and porcine lung injury model. Twelve bronchoalveolar saline-lavaged pigs. Research laboratory in a(More)
To evaluate the efficacy of different lung recruitment maneuvers using electric impedance tomography. Experimental study in animal model of acute lung injury in an animal research laboratory. Fourteen pigs with saline lavage induced lung injury. Lung volume, regional ventilation distribution, gas exchange, and hemodynamics were monitored during three(More)
Evaluation of ventilatory and circulatory effects with coaxial double-lumen tube ventilation for dead-space reduction as compared with standard endotracheal tube ventilation. Experimental study in a pig model of lung lavage induced acute lung injury. University research laboratory. Tidal volumes of 6, 8 and 10 ml/kg body weight with a set respiratory rate(More)
Objective. To evaluate the effects on CO2 washout of the coaxial double lumen tube (DLT) as compared to a standard endotracheal tube (ETT) and tracheal gas insufflation (TGI). Precision of tracheal pressure monitoring through the DLT and safety issues, including intrinsic PEEP (PEEPi) formation during DLT ventilation, were also evaluated. Design. Lung model(More)
