Brief summary
The goal of this study is to assess the ability of a new smartphone PPV app to predict fluid responsiveness in cardiac surgical patients in the Intensive care unit (in the postoperative period)
Detailed description
Pulse pressure variation (PPV) remains a good predictor of fluid responsiveness in the ICU in ventilated and sedated patients. 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 often costly 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.
Interventions
OTHERPPV from the capstesia
we will challenge the application by doing 2 maneuvers: the first one is to increase the PEEP level from 5 to 15 cmH2O and the second one is the infusion of a mini-fluid challenge (100 ml) followed by the other 400 ml.
