Abstract:
Objective To evaluate the efficacies of different ventilatory pattern during one lung ventilation (OLV). Methods During OLV, all patients underwent two different ventilatory pattern, total volume (10ml/kg) without PEEP and half tidal volume (5ml/kg) with PEEP of 7cmH 2O. The arterial blood samples were collected for blood gases analysis immediately before one lung ventilation, 30min following two different OLV pattern and 30 min after resuming two lung ventilation. The airway pressure and hemodynamic parameters were monitored simutaneously. Results PaO 2 and PaCO 2 were higher during half tidal volume than during total tidal volume(P
