Accurate CO Tracking During High-Risk Surgery - Case Study

A head-to-head comparison shows that the Retia Argos Monitor accurately tracks changes in CO as the vena cava is clamped and unclamped during liver surgery, while the leading competitor monitor fails. As shown, the Argos Monitor tracks with the reference standard, while the competitor monitor shows increasing CO when the vena cava is clamped and CO is actually decreasing (205 – 210 minutes), and shows decreasing CO when the vena cava is unclamped and CO is actually increasing (250 – 255 minutes). Over the study time, the competitor monitor shows CO varying between 3 L/min and 4 L/min without reflecting any clear response to the surgical interventions. Accurate tracking is essential for supporting effective clinical decision-making that can prevent shock and optimize resuscitation.
