Overview
Brief Summary
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.
Detailed Description
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.

Eligibility Criteria
Inclusion Criteria
- •patients scheduled for coronary artery bypass
Exclusion Criteria
- •patients with arrhythmias like atrial fibrillation
- •patients with valvular insufficiency
Outcomes
Primary Outcomes
PPV
Time Frame: at time of surgery
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.
Secondary Outcomes
- CO(at time of surgery)
