Oscillometric Arterial Pressure Measurements at Different Limb Sites

Oscillometric Arterial Pressure Measurements at Different Limb Sites: the CUFF-SITE Method Comparison Study

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.

Inclusion criteria:

• Consenting patients ≥18 years scheduled for elective non-cardiac surgery with general anesthesia
• Patients in whom intraarterial arterial pressure monitoring with a radial artery catheter is planned

Exclusion criteria:

• Patients with systolic arterial pressure interarm differences >20 mmHg
• Patients with severe peripheral arterial disease
• Patients with heart rhythms other than sinus rhythm
• Patients with contraindications for peripheral cuff placement (e.g., arteriovenous fistula, skin lesions)
• Pregnant women
