研究概览
简要总结
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)
详细描述
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.

结局指标
主要结局
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)
时间窗: during surgery
We will compare PPV and CO given with the EV-1000 and the capstesia app at different phases of the surgery
