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 conse…
In the operating room the ViTrack™ device will be applied the wrist. Monitoring will start in the operating room and will continue throughout the surgery. The device can be worn on either wrist. It will be connected to a power unit that will capture blood pressure data and stream the data to a secure laptop
