Study 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.

Read the detailed 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

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Baseline to end of monitoring (Approximately 180 minutes)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
