Design outcomes

Primary

Measure	Time frame
1. Validation of the construction of pressure volume loops and end systolic pressure volume relation using transoesophageal echocardiography and continuous non-invasive blood pressure monitoring with the Nexfin 2. Relation between dicrotic notch pressure and beat average pressure 3. Validation of phenylephrine-induced vasoconstriction to use as a loading intervention to construct the end systolic pressure volume relation from a set of pressure-volume loops.	—
