This is an observational study simultaneously comparing finger-sensor and oscillometric with intra-arterial blood pressure measurements in patients having low- to moderate-risk non-cardiac surgery.

| Arterial pressure monitoring | Device | We will record intraarterial arterial pressure, finger-sensor arterial pressure and oscillometric arterial pressure in all included patients. |
| 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 |
| 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. |

| 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 |
