Fluid therapy is essential part of treatment after cardiac surgery. Optimal objective monitoring of its efficacy in hemodynamic stabilization of patients is the subject of ongoing discussion. There are several methods of evaluation of fluid responsiveness and cardiac preload in clinical practice. Among them central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) should be mentioned. On the other hand, systolic pressure variation (SPV) in mechanically ventilated patients is one of the easiest methods of measurement of fluid responsiveness. The purpose of the study was to develop SPV measurement methodology and to apply it as a marker of fluid responsiveness and cardiac preload in patients who underwent coronary artery bypass grafting (CABG) with the use of cardiopulmonary bypass (CPB).
