Group Intervention Description Preoperative Arteriograph A single measurement with an Arteriograph is performed a day before an elective surgical intervention. Intraoperative Arteriograph An arteriograph is put on the patient for the time of operation. The device is set to measure in every 5 minutes. Intensive Care Unit Arteriograph Three separate measurements are performed on the subject with an Arteriograph throughout every dayshift for 3 days.
- Primary Outcome Measures
Name Time Method 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 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.
