Next-generation MedTech systems have made generational leaps in connected, intelligent functionality, leading to improved patient diagnostics, care and outcomes. Yet despite the gains, patients are largely still tethered to the hospital bed, slowing down the recovery process.

Portrait™ Mobile by GE HealthCare was approved by the FDA in 2023 as a first-of-its-kind, continuous monitoring solution that enables patients to move around the hospital while providing uninterrupted oversight. Real-time, uninterrupted data flow monitors vital signs regardless of where the patient is, providing continuous trending and actionable alarms for immediate event detection and treatment.

The backbone of Portrait Mobile is data-centric software that is based on Data Distribution Service (DDS™), the publish-subscribe middleware standard. This data-centric software architecture enables flexible, real-time and continuous connectivity for mobile monitoring. The data framework also addresses the simultaneous and demanding interoperability, reliability, cybersecurity, safety and performance requirements.

This talk will provide an introduction to DDS, followed by a discussion of how DDS is used in Portrait Mobile architecture to deliver highly-reliable information flow over a mobile, distributed system.
