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

IEEE 1073QoS Requirements

EXAMPLE:Real-time Alarm Very high reliability

(100%) < 10 second latency Very high priority Low, intermittent

bandwidth

Real-time Waveform High reliability

(10 s/day) Latency (?) High priority High, predictable

bandwidth
