Current Wireless Technology • Closed Circuit Television (CCTV) in Intensive Care Units • Remote Alarms
Implanted Wireless Devices • Couple the sensor to the actuator • Ex. Diabetic patients • Glucose meter – implanted insulin pump • Wireless Microchips • Epilepsy • Parkinson’s disease
Homecare • Continuous Monitoring of Physiologic Parameters • ECG • NIBP • SpO2 • Pill Boxes
“SmartShirt” Georgia Tech Wearable Motherboard™ • Georgia Tech • Funded by U.S. military • Plastic optical fiber • T-connectors form flexible bus • ECG, RR, temperature • Ex. Geriatric / mentally ill / SIDS • Ex. Firefighting
Plug-and-Play Interoperability WHY IT IS NEEDED: • Specialized applications / multiple vendors • Medical devices and clinical information systems • No time for configuration or set-up programs
Plug-and-Play Interoperability FACTORS TO CONSIDER: • Safety • Unambiguous association • Reliability • HL7 Interoperability • Security • Scalability
