Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients who have undergone cardiac surgery and have a pulmonary artery catheter in place.

Probably not a fit

Patients experiencing hemodynamic instability or those who cannot provide consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to compare cardiac performance in patients undergoing cardiac surgery by measuring stroke-volume-index using three different methods: pulmonary artery catheter, FloTrac®, and Argos®. Investigations will take place in the operating theater and ICU, involving both ventilated and spontaneously breathing patients. The study will help determine the most effective method for hemodynamic monitoring in this patient population.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of cardiac performance monitoring in patients undergoing cardiac surgery.

How similar studies have gone: While there have been studies on hemodynamic monitoring, this specific comparison of these three methods in cardiac surgery patients is relatively novel.
