Multi-Beat Analysis Technology (MBA) for Clinical Impact - Medical / Health Care - Clinical Services
Accurate CO monitoring is essential for effective, proactive hemodynamic management, especially for patients in whom CO is low or changing. An independent study at New York-Presbyterian/Columbia University Medical Center conducted in 40 liver transplant and cardiac surgery patients in the OR or ICU using continuous PA catheter as the reference showed that the Argos Monitor was 50% more accurate than the market leader’s monitor, and that it was 45-50% better in patients with CO < 5 L/min or with changing CO status.

More accurate than the leading competitor based on esophageal Doppler
The Argos Monitor has also demonstrated high accuracy in a study of 40 high-risk surgeries (27 neurosurgeries and 13 hepatobiliary surgeries) using esophageal Doppler as the reference [Retia Medical data on file].
