Measurement of Pulse Pressure Variation and Cardiac Output by a New Application for Android™ (Captesia™)
- Conditions
- Coronary Bypass
- Registration Number
- NCT02692222
- Lead Sponsor
- Erasme University Hospital
- 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.

- Primary Outcome Measures
Name Time Method PPV 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 Outcome Measures
Name Time Method CO at time of surgery 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.
