简要总结
A study to observe the effect of variations in ventilator settings including tidal volume and PEEP on transpulmonary pressure monitored with an esophageal balloon catheter and to correlate intraoperative transpulmonary pressure variations and intraoperative stroke volume variation changes.
详细描述
This study seeks to observe the effects of variations in ventilator settings on transpulmonary and intrathoracic pressures. More specifically, to observe the impact of variations in tidal volume from 6 mL/kg to 8 mL/kg and PEEP from 0 cm of water (H2O) to 5 cm H2O on transpulmonary and intrathoracic pressures monitored with an esophageal balloon catheter. The impact of this recommended decrease in tidal volume on the clinical utility of stroke volume variation (SVV) as a guide for fluid administration has not been previously examined.
