1. Accessible Home Vital Signs Monitoring System Kristyn Eilertsen Adam Goodale Stephen Kepper Sunil Narayan Stacey Tarver Group 22 BME 272 Advised by Paul King,Ph.D and John Enderle Ph.D

2. National Student Design Competition Rehabilitation Engineering Research Center on Accessible Medical Instrumentation $2000 reimbursement for design costs 3 possible design projects Design Project: Accessible Home Vital Signs Monitoring System Acceptance through letter of intent- design approach, completion date, contact information

3. Problem Statement Multimodal home vital signs monitor  Body temperature  Weight  Blood pressure  Heart rate  Respiration rate  Blood oxygen level

4. Patient Challenges Must accommodate patients with varying disabilities  Blind  Deaf  Elderly  Bed ridden  Motor movement challenged  Little technology experience

5. Requirements User friendly Cost effective Visual usage Audio usage Large responsive user interface Compact Aesthetically pleasing Fast response Telemedicine

6. Limitations Unable to acquire weight information on bed ridden patients Cannot cost over $2000 (project fund) Must be completed by end of Spring semester

7. Changing the Face of Healthcare Number of hospital emergency departments cut by 14% in 2005 ER visits reached a record high of 114 million, consisting primarily of the uninsured and elderly US 65-and-over population has risen 9.6% over that same time period

8. Why target the elderly? ER visits by Americans age 65 and over rose 26% in 2003 Medicaid patients were four times more likely to seek treament in an ER than those with private health insurance Nursing home residents age 65-74 were five times more likely to visit the ER than non institutionalized seniors

9. Components Vital sign devices:  Force plate (scale)  Breathing rate sensor  Pulse oximeter  Blood pressure sensor  Temperature probe  Computer Blood pressure Temperature Oximeter Breathing rate Weight scale Heart rate

10. Estimated Prices Desktop computer ………………..$ 330.00 Heart rate sensor …………………$ 114.00 Blood pressure sensor …………..$ 99.00 Breathing rate sensor………........$ 137.00 Weight scale …………………….. $ 199.00 Temperature probe ………………$ 29.00 Pulse oximeter ……………………$ 165.00 Data analysis software …………..$ FREE Go Link software …………………$ 59.00  TOTAL: $1132.00

11. Current Status Set up account with Janiece Harrison Submitted purchasing order forms for sensors and computer Decided against voice activation software because blind patients have live in assistance Determining compatibility of foreign pulse oximeter with software  0 – 5 Volt input requirement  Calibration requirement

12. Software Compatibilities Matlab  Developing Matlab based program Graphic User Interface (GUI) Visual Directions Voice Response  Verbal directions to user  Verbal communication of results Ability to call C++ Create DLL file Vernier and C++  GoLink! code written in C++  Filter code to specified needs

13. Data Acquisition C++ program communicates with sensor  communicates through USB  sets sampling rate, collects and stores data  Sends results to Matlab Displays to patient Stores data in file  Saved as date and time

14. Telemedicine Email Results  Uses C++ to create email with attached results  Uses stored patient and doctor email in setup screen  Ability to retrieve and send past results  Security protected through username and password

15. Conclusion In the near Future….  Continue formatting C++ and Matlab code  Integrate sensors  Test sensor quality Compare to actual medical devices  Create stand alone computer program
