About

This prospective, single-center observational study aims to evaluate the measurement performance of oscillometric arterial pressure measurements at different limb sites. Specifically, oscillometric arterial pressure measurements obtained at the upper arm, forearm, thigh, and lower leg with intraarterial arterial pressure measurements will be compared in non-cardiac surgery patients.

The results will provide insight into the reliability and accuracy of oscillometric blood pressure readings at alternative limb sites in clinical practice.

Enrollment: 84 patients
