Brief summary
This study test the agreement and precision of Pulse Pressure Variation (PPV) and Cardiac Output (CO) obtained by the Android application Capstesia™ against another pulse contour CO monitoring ( EV-1000, Edwards Lefesciences, USA)
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Agreement and precision of PPV and CO during 5 surgical phases (postinduction, pre incision, postincision, end of surgery and at least one episode of hypotension) | during surgery | We will compare PPV and CO given with the EV-1000 and the capstesia app at different phases of the surgery |
