Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Difference in the agreement between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements, and the agreement between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements	To investigate whether the agreement between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) is better than the agreement between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements, we will perform Bland-Altman analyses.	During surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Classification of measurement differences between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance	To classify measurement differences (mean arterial pressure and systolic arterial pressure) between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance, we will perform error grid analyses.	During surgery
Classification of measurement differences between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance	To classify measurement differences (mean arterial pressure and systolic arterial pressure) between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance, we will perform error grid analyses.	During surgery
Ability of finger-sensor arterial pressure monitoring to track arterial pressure changes compared to intraarterial arterial pressure monitoring	To investigate the ability of finger-sensor arterial pressure monitoring to track arterial pressure changes (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) compared to intraarterial arterial pressure monitoring, we will compute four-quadrant plots and calculate the concordance rate.	During surgery
Ability of oscillometric arterial pressure monitoring to track arterial pressure changes compared to intraarterial arterial pressure monitoring	To investigate the ability of oscillometric arterial pressure monitoring to track arterial pressure changes (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) compared to intraarterial arterial pressure monitoring, we will computer four-quadrant plots and calculate the concordance rate.
