ViVE Bonus: Marc Zemel on Real-Time Hemodynamic Monitoring and Early Deterioration Detection in Critical Care

Recorded at the 2026 VIVE conference in Los Angeles, this Beyond Longevity mini-series episode features Mark Zemel, co-founder and CEO of Retia Medical, discussing the company’s hemodynamic monitoring technology that turns continuous bedside physiological signals into real-time clinical insights for high-risk surgery and critical care.

Marc explains Retia’s aim to detect early deterioration, guide diagnosis and therapy, and avoid the unreliability, invasiveness and complexity of older tools, noting deployment in 75 US hospitals and distribution via Medtronic, plus presence in 18 countries.

He highlights FDA clearance for Argos Infinity enterprise software, which extends insights across the hospital and to clinicians’ phones and laptops, and shares a case where rapid detection of falling stroke volume revealed bleeding during AAA repair. The conversation covers workflow-first design, interoperability, cybersecurity, regulatory strategy, and a future path from ICU to broader wards and ultimately wearables for earlier intervention and preventative care.
