Fluid Responsiveness Clinical Trial
— Nexfin2Official title:
Accuracy of Pulse Pressure Variation (Nexfin) and of Pleth Variability Index (Radical 7) to Predict the Response to a Fluid Challenge: Comparison With the Reference Method (Measurement of Stroke Volume by Esophageal Doppler)
The aim of this study is to compare the accuracy of Pleth Variability Index (Radical 7 device) and of Pulse Pressure Variation (Nexfin device) with the Doppler measurement of stroke volume (esophageal Doppler) to detect the response to a fluid challenge.
