Официальное название

Comparison of Peripheral Venous Pressure Variation, Pulse Pressure Variation and Pleth Variability Index in Predicting Fluid Responsiveness

Обзор

Pulse pressure variation (PPV) and pleth variability index (PVI) are widely used in clinical practice as indicators of the responsiveness to fluid therapy in patients receiving mechanical ventilation. PPV, which measures changes in arterial pressure, requires arterial puncture, which is invasive, and PVI, which detects subtle changes in oxygen saturation, requires an expensive, commercial monitoring equipment. In this study, we aimed to measure peripheral venous pressure variation using less invasive waveform variation in peripheral veins and to determine whether this indicator can be clinically used to predict the responsiveness to fluid therapy. In addition, the investigators aimed to confirm the superiority of the indicators by comparing them with the responsiveness to fluid therapy of the PPV and PVI.

Другое peripheral waveform collection
The peripheral venous pressure is collected by connecting a pressure transducer that is currently in use to the central venous line. In addition, pulse pressure variation and stroke volume variation that can be obtained from the arterial catheter. In addition, the pleth variability index is collected through the oxygen saturation monitoring. This extracts the medical records and bio-signal information of the subjects registered through the previously approved 'Establishment of a Bio-signal and C
