Agenda• Introduction

– Motivation– Solutions

• System Overview– Handheld Tablet– Whiteboard– Database

• Timeline and Budget• Future Work• Lesson’s Learned• Conclusion


Introduction• Total emergency health services (EHS) package• Consists of three components:

1. Handheld Tablet2. Whiteboard 3. Database

• Increase hospital emergency room (ER) efficiency

• Reduce length of stay and cost


Basic Medical Process : Paramedics and Emergency Room

Paramedics1. Arrives at scene (Patient

Care Report begin)2. Transport patient to

hospital3. Arrives at hospital4. Provide triage nurse of

their assessment of injury

ER Nurse5. Patient admits to hospital6. Triage nurse starts

comprehensive Triage Nursing Assessment

7. Prioritize patient based on CTAS score (level of severity)

December 15th, 2010 ENSC 440 Presentation 5

Motivation• Current Emergency Response System– Radio/Telephone Communication– Paramedic and ER nurse triage– Falling behind to demand– National benchmark is 8 hours for admitting a

patient, and 4 hours for discharging a patient


Solution• Allow hospital to receive multiple inquiries– Efficient– Trouble-free– Reliable

• Allow hospital to receive information early and prepare for incoming patients

• Reduce redundancy• Enhance communication between Paramedics

and Nurses

Future Work

• Implement level III and IV features in the functional specification– 3G networking– Battery pack and power management– 10” Display– Touch Screen performance

• Design a nicer and more compact casing• Prototype field test by the paramedics


Lessons Learned• User Interface Design• Embedded Linux Programming • Database Design and Construction• Wireless Communication• Image Capturing and Camera Interfacing

• Teamwork• If you don’t know it, learn it and apply it!


Conclusion• System designed to improve efficiency at ER• A proof-of-concept model is constructed and

tested • Future works concentrated on system

performance and user feedbacks

• Great course!• Wonderful experiences!
