ViTrack, blood pressure monitoring
Brief summary
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.
Interventions
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
