FHIR & Shen AI: Unlocking scalable AI health monitoring through modern interoperability

In digital health, the value of a vital-sign measurement is realized only when that data reaches the right system at the right time. For organizations already utilizing FHIR (Fast Healthcare Interoperability Resources), the challenge isn’t understanding the standard - it’s ensuring that new data sources, like camera-based monitoring, can be integrated into existing clinical or insurance workflows without significant friction.

Shen AI is designed with this interoperability in mind. While Shen AI is not a FHIR server or a data-routing engine, its SDK provides the structured, stable outputs necessary for developers to map vital signs into FHIR resources with minimal effort.

Architecture: Where Shen AI ends and FHIR begins

It is important to clarify the technical boundary: Shen AI acts as a specialized measurement layer. The SDK captures and processes camera-based signals, then delivers one-way, high-fidelity health outputs directly to the partner’s application. From that point onward, data persistence, routing, orchestration, and business logic remain fully within the partner’s infrastructure.

However, we make this transition seamless by ensuring our SDK outputs align with the logic of FHIR:

• Predictable JSON Schema: Every measurement (Heart Rate, HRV, Blood Pressure, etc.) uses consistent naming and formatting.
• Metadata Richness: Outputs include precise timestamps and measurement quality indicators - essential fields for valid FHIR resources.
• One-Way Integration: We provide the "payload"; your system defines the "destination."

Turning SDK outputs into FHIR Resources

Because the SDK’s data structure is stable and well-defined, mapping Shen AI results to standard FHIR resources is typically straightforward. Most partners complete this step within days, adapting the mapping to their specific workflows and regulatory context.

• Observation: The primary resource for Shen AI data. Each vital sign  (heart rate, HRV, breathing rate) is delivered in a format ready to be wrapped in a FHIR Observation, complete with coding (LOINC/SNOMED) defined by the partner.
• RiskAssessment: Shen AI’s health risk indicators (e.g., hypertension risk or metabolic health indices) provide the raw data required to populate RiskAssessment resources for triage or underwriting.
• Device: The SDK can be referenced as the "source" or "device" in EHR documentation to ensure auditability and clinical traceability.

Why structure data matters

Shen AI does not aim to replace the interoperability layer. Instead, it focuses on delivering measurement technology that fits naturally into FHIR-based ecosystems.

By providing FHIR-ready outputs, Shen AI helps partners:

1. Reduce integration overhead: Developers don’t have to "clean" or "translate" Shen AI data. It is already structured for straightforward conversion into JSON-based FHIR resources.
2. Maintain a longitudinal record: Because the data maps easily to standard resources, it can be stored alongside lab results and wearable data in the partner's clinical data repository.
3. Support automated triage: Once a partner converts a Shen AI scan into a FHIR Observation, they can trigger their own internal rules, such as alerting a clinician or routing a user to a specific care program.

The developer perspective: Integration efficiency

Shen AI does not host or manage the "flow" of data between systems. Instead, we focus on Output Stability. Whether you are integrating vitals into a telemedicine intake form or an insurance underwriting engine, the SDK provides the raw materials.

The SDK’s predictable schema includes:

• Consistent field naming across all metrics.
• Measurement duration and stability metrics.
• Contextual data that allows partners to link measurements to specific ‘Patient’ or ‘Encounter’ IDs within their own FHIR-compliant backend.

A foundation for interoperable health

Shen AI delivers the what: accurate, camera-based vital-sign measurements. FHIR provides the how: a standardized framework for storing and exchanging health data across systems.

By designing its outputs specifically for FHIR mapping, Shen AI enables modern AI health monitoring to integrate into existing technical architectures without forcing teams to rebuild their infrastructure or compromise on interoperability.
