Performance Evaluation of the ViTrack Continuous Non-invasive Blood Pressure Measurement Device

Performance Evaluation of the ViTrack Continuous Non-invasive Blood Pressure Measurement Device

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.

Inclusion Criteria:

• 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
