Finger-sensor and Oscillometric Versus Intra-arterial Blood Pressure Measurements

Finger-sensor and Oscillometric Versus Intra-arterial Blood Pressure Measurements: a Method Comparison in Patients Having Non-cardiac Surgery

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.

Inclusion Criteria:

• ≥18 years
• scheduled for elective low- to moderate-risk non-cardiac surgery with general anesthesia
• planned intraarterial arterial pressure monitoring with a radial arterial catheter

Exclusion Criteria:

• systolic arterial pressure interarm differences >20 mmHg
• heart rhythms other than sinus rhythm
• contraindications for finger-sensor arterial pressure monitoring (e.g., arteriovenous shunts, Raynaud's disease)
• surgery in non-supine positions
• pregnant patients.
