This study test the agreement and accuracy of Pulse Pressure Variation (PPV) and Cardiac Output (CO) obtained by the Android application Capstesia™ against the gold standard : PPV and CO calculated by thermodilution.
Pulse pressure variation (PPV) remains a good predictor of fluid responsiveness in the OR. However, PPV can be time-consuming to calculate (manual determination), is not always displayed on monitoring screens nor reliable through visual assessment and needs additional devices to be displayed. A new Android application (Captesia) automatically calculates the PPV utilizing a digital photograph of the arterial waveform from the monitor. The application determines the PPV by selecting peaks and troughs of the arterial curve.

PPV
the Pulse Pressure Variation will be calculated by the Android Application (Captesia) and by the Picco before and after a meneuver of volume expansion, which goal is to change the cardiac output.
Time frame: at time of surgery
CO
the Cardiac Output will be calculated by the Android Application (Captesia) and by thermodilution before and after of volume expansion, which goal is to change the cardiac output.
Time frame: at time of surgery
