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.00:00 Beyond Longevity Intro00:44 Meet Mark Zeel01:40 Rata Medical Mission02:54 Argos Infinity Launch03:58 Clinicians Want Real Time05:19 Surgery Near Miss Story07:20 Why Accuracy Matters08:42 Why Algorithms Are Hard10:08 From ICU To Wearables12:20 Scaling Distribution Globally13:22 Plug And Play Integration15:22 Wearables And Data Overload18:31 Alerts And Clinical Judgment20:16 AI As Decision Support21:56 US Versus Europe Markets23:09 Wearables Beyond EMRs23:57 Regulation And Cybersecurity25:07 FDA And AI Pathways26:50 Clinician Workflow Design29:39 Bad Data From Friction31:58 Open Ecosystems Future33:25 Prevention And Longevity35:46 Personal Why Wearables Matter39:24 From ICU To Early Detection41:44 Rapid Fire And Wrap
