Accessible Home Vital Signs Monitoring System Group 22 BME 272 Kristyn Eilertsen Adam Goodale Stephen Kepper Sunil Narayan Stacey Tarver

National Student Design Competition Sponsored by Rehabilitation Engineering Research Center on Accessible Medical Instrumentation Problem: Increase in healthcare costs require the need for medical tasks to be moved into the home Aim: Design an affordable, at-home vital signs monitoring system, that can transmit medical information Specs: collect 4-6 vital signs, store/retrieve data, easy to use, accessible at home

Project Background The growing number of elderly people means even more stress will be placed on emergency rooms Currently at home vital systems or personal nurses are too expensive for everyone to use

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

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

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

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

Components Multimodal home vital signs monitoring system Body temperature Weight Blood pressure Heart rate Respiration rate Computer Blood pressure Weight scale Temperature Breathing rate Heart rate

Sensor Range and Accuracy Vernier Sensors Very accurate Inexpensive Sensors Blood Pressure Sensor Range: 0-250mm Hg, Accuracy: +/- 3mm Hg Force Plate Range: 0 – 1000lb, Accuracy: +/- 0.25lb Temperature Probe Range: -40C to 135C, Accuracy: +/- 0.2-0.5C Breathing Rate Range and Accuracy: Contact Vernier Heart Rate Monitor
