I’ve spent plenty of time wrestling with WebSockets in my career, but things get a lot more intense when you're dealing with live cardiac vitals and patient privacy. If you’ve ever wondered how to keep real-time data snappy without leaking sensitive location data, this is a great deep dive.
It walks through the architecture of Halkyone Clinical OS, showing how they use SignalR to bridge the gap between .NET backends and React frontends for mission-critical healthcare workflows.
Isolation of concerns using three specialized SignalR hubs (ChatHub, TelemetryHub, and NotificationHub) to manage distinct data streams.
Implementation of a 500m privacy radius that uses the Haversine Formula to obfuscate clinician coordinates to (0,0) when they get too close to a patient’s home.
Real-time streaming of IoT telemetry, specifically focusing on sub-second synchronization for heart rate and SpO2 vitals.
