Argos system to track cardiac output changes in critically ill patients
Official title: Evaluation of the Argos System to Estimate Cardiac Output in Critically Ill Patients
Run by Bicetre Hospital · NCT07724262 · Data updated 2026-11-12
This study tests whether the Argos monitor can reliably track how cardiac output changes after fluid administration or norepinephrine adjustments in critically ill adults already monitored with transpulmonary thermodilution.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) in intensive care with established transpulmonary thermodilution monitoring and requiring a fluid bolus or norepinephrine adjustment.
✕Probably not a fit
Patients without a need for fluid or vasopressor changes or without existing TPTD monitoring may not benefit from Argos tracking.

What this trial studies
This observational study compares the Argos monitor's multi-beat analysis to the transpulmonary thermodilution reference for tracking changes in cardiac output during fluid boluses or vasopressor adjustments in patients with acute circulatory failure. It sits in ICU settings where PiCCO2/CIpwa measurements are used, examining real-time CI changes and how well Argos aligns with the established method. The study leverages existing invasive monitoring to assess whether a less invasive or alternative waveform-based estimate can reliably detect hemodynamic shifts. Outcomes focus on agreement between Argos-derived CI and the TPTD-based CI changes during intervention. The trial is sponsored by Bicêtre Hospital and conducted at Bicêtre Hospital in Le Kremlin-Bicêtre.
Why it matters
Potential benefit: If successful, Argos could provide a reliable, less invasive way to monitor cardiac output changes in ICU patients.
How similar studies have gone: Previous work on hemodynamic monitoring devices shows promise for waveform-based CI estimation, but this exact Argos approach in this setting is formative/investigational.
