Conditions

Intraoperative blood pressure monitoring

Interventions

Group 1: We aim to analyze the automatically collected circulatory data from patients undergoing elective surgery in the prone position. Despite the presence of invasive blood pressure (IBP) monitorin

Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: • Patients undergoing elective surgery in the prone position • Patients scheduled to receive invasive blood pressure (IBP) monitoring

Exclusion criteria

Exclusion criteria: • Patients under 18 years of age • Patients undergoing emergency (non-elective) surgery • Patients not receiving or not scheduled to receive invasive blood pressure (IBP) monitoring • Patients for whom non-invasive blood pressure (NIBP) measurement on the upper arm is not feasible (e.g., due to a dialysis shunt)

Design outcomes

Primary

Measure	Time frame
Does the prone position affect the measurement accuracy of non-invasive blood pressure (NIBP) compared to invasive blood pressure (IBP), in contrast to the supine position?	—

Secondary

Measure	Time frame
Examination of the arterial blood pressure waveform for damping phenomena Number of manual blood pressure measurements	—
