Overview
The purpose of this study is to calibrate the ViTrack™ arterial pressure waveform against intra-arterial pressure (IAP) in dynamic clinical settings and to assess the optimized ViTrack™ design to measure and continuously track blood pressure over a wide, clinically-relevant pressure range.
Eligibility

- scheduled to undergo noncardiac surgery with general or spinal anesthesia
- clinical indication for invasive intra-arterial pressure monitoring
- palpable pulse
Exclusion Criteria:
- difference of greater than 10 mmHg in the left versus right arm oscillometric systolic blood pressure
- Upper extremity arteriovenous hemodialysis shunt
- Upper extremity amputation
- Planned surgical position/draping that precludes access to the wrist
- Wrist distortion or pain from arthritis
- Prior trauma or surgery at the radial artery monitoring site
- Unable to provide informed consent
- Clinical contraindication as determined by the clinical team or study investigators
