Design outcomes

Primary

Measure	Time frame	Description
Number and degree of hypotensive episodes predicted by preoperative values of pulse wave velocity.	One year	The investigators will examine if high values of pulse wave velocity correlate with the frequency and severity of hypotensive episodes under anaesthesia.
Correlation between systemic vascular resistance and aortic augmentation index	One year	—
Identity of cardiac output given by the PiCCO monitor and cardiac output given by the Arteriograph	One year	—
