GE DRI Protocol Parser

A Rust implementation for communicating with GE Healthcare patient monitors (CARESCAPE B650/B850, S/5) using the Datex-Ohmeda Record Interface (DRI) protocol over serial RS232.

This tool can capture physiological data (heart rate, SpO2, blood pressure, temperatures, CO2, ventilator parameters, etc.) and waveforms (ECG, plethysmograph, etc.) from compatible monitors.

Binaries

Main Application

Full-featured data collection with CSV/JSON export and interactive configuration.

cargo run --bin ge-dri-prototype

Or after building:

./target/release/ge-dri-prototype

Diagnostic Tool

Simple diagnostic mode that auto-starts and logs all received data to console. Useful for testing connectivity.

cargo run --bin diagnostic

Faker (Simulator)

Simulates a GE monitor for testing without real hardware. Generates fake physiological data and waveforms.

cargo run --bin faker -- --port COM3

Or on Linux:

cargo run --bin faker -- --port /dev/ttyUSB0
