  1. Markus NilssonDept. Of Computer Science and EngineeringMälardalen UniversityVästerås, Sweden

  2. Project X? Industrial funded PhD Student Funding: • KK-stiftelsen 50% • Stress Medical Innovation & Development AB 40% • Mälardalen University 10%

  3. A Medical System • Analyze measurements • Diagnose patient status • Predict future symptoms

  4. Related research • Stress medicine: One group in Israel and one in Texas, USA. • AI - CBR: • Janet L. Kolodner, Georgia Institute of Technology, USA • Ian Watson, University of Auckland, New Zealand. • Roger C. Schank, Institute for the Learning Science, Northwestern University, USA

  5. Related projects • No similar projects exists combining stress medicine and AI. • Medical diagnosis and CBR: TROPIX -Tropical disease diagnosis and treatment • Medical diagnosis and RBR: MYCIN, PUFF ...

  6. Facts & Figures • A spin-off company from Karolinska Institutet • Focused on development • Specialized in diagnosing and treatment of stress related diseases • Located: Karolinska Institutet, Stockholm Uppsala Science park, Uppsala • Aprox. 6 employees • One product released – AirPas(2001)

  7. Current system Report lpr Electronics, A/D converters Expert System PC Patient Expert Air-Pas • Sensors, electronics, pc, expert system • Rules derived from the company expert, PhD Bo von Schéele • Automatically generates a report Illustrations adapted from Peter Funk

  8. AirPas Measuring: • Oxygen saturation (Sa02) • Blood Volume Pulse (BVP) • Heart Rate (HR) • Carbon dioxide levels (CO2)

  9. AirPas Calculating: • Top level of CO2, (ETCO2) • Respiration Rate (RR) Collecting data from several sessions under different conditions

  10. Problems Limited ability to diagnose Maintenance & Brittleness Only Bo can do a complete diagnose Domain limitations – e.g. Yoga Supervisor required

  11. Research Challenges • Eliminate the need for an expert • Produce more accurate diagnosis • Suggest treatment • Solve problems outside the knowledge of current system • Handle unknown situations • Learn and improve • Share the knowledge

  12. Summary • Stressmedicine and AirPas. • Rule Based reasoning not sufficient • Little related research (CBR & Medicine).
