Primary Outcome Measures

Name	Time	Method
Incidences of postoperative hypotensive episodes identified by continuous non-invasive finger-cuff blood pressure monitoring. A postoperative hypotensive episode will be defined as a MAP <65 mmHg for at least one consecutive minute assessed by continuous non-invasive finger-cuff blood pressure monitoring.

Secondary Outcome Measures

Name	Time	Method
Secondary endpoint #1: the cumulative duration patients had a MAP <65 mmHg (min)<br>Secondary endpoint #2: the area under a MAP of 65 mmHg (mmHg x min)<br>Secondary endpoint #3: the time-weighted average MAP less than 65 mmHg (mmHg)<br><br>Exploratory endpoints: Primary and secondary endpoints below MAP thresholds of 70 mmHg and 80 mmHg<br>
