Clinical Trial Summary

The aim of this study is to determine the effects of fluid alternations, hemodynamic changes, mechanical ventilation, pharmacologic agents, positional changes, and comorbidities on the Peripheral Intravenous waveform Analysis (PIVA) signal.

Description:

Intravascular volume status determination remains elusive. Standard vital sign monitoring, including heart rate and blood pressure, fails to detect intravascular volume depletion and volume overload. Likewise, invasive monitoring is fraught with risk including vascular injury and central line associated infections. As such, a minimally-invasive mechanism to overcome the barriers of standard monitoring to detect volume status derangement, would be highly valuable. The goal of the study is to perform a series of observational feasibility studies in healthy and hospitalized subjects to determine effects of fluid alternations, hemodynamic changes, mechanical ventilation, pharmacologic agents, positional changes, and comorbidities on the PIVA signal

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation of PIVA score to standard hemodynamic monitors	Peripheral intravenous waveform analysis score is used to detect intravascular volume status. The scale ranges from 2-40 and is interpreted as a surrogate for pulmonary capillary wedge pressure. The normal scale range is 6-12. A PIVA score of 2 indicates a low intravascular volume and 40 indicates a high intravascular volume.	Baseline to end of monitoring (Approximately 180 minutes)
