Profusa, a digital health company known for its Lumee™ biosensor platform, is teaming up with NVIDIA to build what could become one of the most ambitious AI-powered health data systems yet: a continuous biochemistry monitoring portal designed to link real-time patient chemistry with electronic medical records (EMRs).
The goal? To fill what Profusa CEO Ben Hwang calls a “missing dataset” in healthcare—real-time biochemical insights at scale. According to Hwang, combining Lumee’s data with NVIDIA’s NeMo AI software and hardware stack could create a backbone for more accurate biosensor readings, seamless EMR integration, and predictive treatment pathways.
Why This Matters
Wearables today track vitals like heart rate and blood oxygen, but biochemical data—such as molecular changes in tissue—remains out of reach for most clinicians. Profusa wants to change that by making continuous chemistry monitoring part of everyday care. If successful, this could bridge a massive gap between today’s reactive medicine and tomorrow’s predictive, precision healthcare.
With NVIDIA onboard, the plan is to scale that vision, leveraging accelerated computing and large language models (LLMs) to turn raw sensor feeds into actionable intelligence.
What’s Coming in the Portal
Profusa outlined an ambitious feature set for its forthcoming physician-facing portal:
- Agentic clinical workflows: An LLM-powered assistant that integrates with EMRs, wearables, and home devices, helping clinicians generate notes, manage orders, build care plans, and oversee remote patient monitoring.
- Built-in evaluation tools: Metrics and testing frameworks to monitor AI assistant accuracy, drift, and safety over time.
- Guardrails by design: Policy-driven orchestration enforcing data privacy, safe responses, and scope control for patient-provider interactions.
- Customizable model training: Options ranging from efficient fine-tuning to post-training refinements for Profusa’s AI signal processing and reasoning modules.
- Time-aligned health graph: A longitudinal dataset combining Profusa biomarkers with EMR entries, pharmacy claims, wearable data, genomics, imaging, and social determinants of health.
In short, the system aims to become a real-time, multimodal health intelligence engine that not only tracks what’s happening biochemically but also forecasts where a patient’s health may be headed.
Industry Context
AI-driven clinical assistants are nothing new—Microsoft is embedding Copilot into Azure Health, while Google’s Med-PaLM and startups like Hippocratic AI chase the same space. What Profusa brings to the table is proprietary, real-time biochemical data—something few others can claim.
That could be the differentiator. If Lumee’s continuous monitoring proves accurate at scale, Profusa could give clinicians a new type of visibility: biochemical context that augments vitals, labs, and imaging to improve decision-making.
The Bottom Line
By pairing its biosensor data with NVIDIA’s AI stack, Profusa is setting its sights on a high-stakes frontier: predictive, data-rich healthcare that’s both personalized and scalable.
The challenges—data privacy, regulatory compliance, and clinical validation—are enormous. But if Profusa delivers, the company may finally unlock the “missing dataset” that could shift AI in healthcare from speculative to indispensable.
