An Intelligent Patient Monitoring System for Hospital ICUs

1. An Intelligent Patient Monitoring System for Hospital ICUs Douglas Marzella Nicholas A O’Donoughue Advisor: Dr. Sarvesh Kulkarni

2. Overview • Problem Statement • Project Objectives • Design Overview • Wireless Sensor Network • Data Acquisition and Alert Module (DAAM) • ICUClient • User Interface • Conclusions

3. Problem Statement • Hospital ICU • Patients require constant monitoring • Vital parameters slip below safe range • Nurse responds to audio alarm • Nurse pages doctor • Doctor responds • Results in delay

4. Project Objectives • Create a portable easy to use monitoring and alert system for doctors • Patient information accessible from anywhere with wireless internet • Send alerts for dangerous patient vital signs directly to a doctor

5. Design Overview • Wireless Sensor Network (WSN) • gather patient data • send data to DAAM • Data Acquisition and Alert Module (DAAM) • record and monitor data • communicate withICUClient • ICUClient • connect with DAAM viaWi-Fi • display data graphically

6. Wireless Sensor Network • Multi-hop Wireless network • Sensor nodes connect to Ethernet base station • Used Factory routing algorithm • Very minor changes made • All sensors had to be reprogrammed • Sensors mimicked patient data

7. DAAM • MySQL Database • Logger • connect to WSN • log data • monitor data for emergencies • PalmServer • wait for connections • spawn a PalmServerThread for each connection • PalmServerThread • respond to requests • UpdateThread • provide streaming data to ICUClient

8. ICUClient • ICUClientMIDlet • controller class • Communicator • handle sockets • 5 different ‘screens’ • visual interface • Graph • plot streaming data • used by DataScreen

9. User Interface

10. Starting the ICUClient • Start the ‘ICUClient’ • WelcomeScreen • Options: • Configure the IP of the DAAM • Connect to the DAAM • Quit

11. Configure the IP Address • Displays the current settings for server IP and port • IPConfigScreen • Options: • change settings and save • cancel (use current settings)

12. Looking at a Node List • Receive a list of the active nodes from the DAAM • NodeListScreen • Options: • refresh list • request snapshot of a node • quit

13. Node Snapshot • Displays the most recent readings from all of a node’s sensors • SnapshotScreen • Options: • refresh snapshot • back to Node List • request streaming data

14. Streaming Data • Graphs data inreal-time • DataScreen • calls Graph • Options: • sit and watch • back to snapshot

15. EMERGENCY: Sending an Alert • Monitoring equipment recordsabnormal value • Heart rate=10 bpm • DAAM receives abnormal record • Dispatches alert to every user

16. EMERGENCY: Receiving an Alert • ICUClient receives an AlertMsg • ICUClient displays alert • Pop-up window • Patient information isdisplayed in pop-up • Palm ‘beeps’ and ‘vibrates’according to userpreferences

17. Publications • To be presented at 2006 Americas Conference on Information Systems (AMCIS 2006), Acupulco, Mexico • Submitted to 2006 IEEE Engineering in Medicine & Biology Conference (IEEE/EMBC 2006), New York City

18. Conclusions • Viable Real-World System • Low-cost COTS hardware • Much work to be done • Thank you for yourtime • Demonstration tofollow presentations
