Several peer-reviewed clinical studies have evaluated the utility of the currently available measurement PVi as an indicator of fluid responsiveness in mechanically ventilated patients. For example:
- In a study of 82 patients undergoing major abdominal surgery, researchers found that PVi-based goal-directed fluid management reduced the volume of intraoperative fluid infused and reduced intraoperative and postoperative lactate levels.2
- In a study of 109 patients undergoing colorectal surgery, researchers found that the implementation of an enhanced recovery protocol which included PVi led to improved patient satisfaction and substantial reduction in lengths of stay, complication rates, and costs for patients undergoing both open and laparoscopic colorectal surgery.3
