Problem
 Individuals with cardiovascular diseases that
are not motivated to continue in a proactive
approach to improving their well-being are at
a higher risk of having future cardiovascular
problems.

Cardiac Rehabilitation Phases
 Phase I
 Inpatient
 Hospital staff will take the patient for a walk
 Phase II
 Outpatient
 Patients come into the hospital for monitored exercise
 Phase III
 Maintenance
 Patients have to exercise on own
 Usually joining a gym or recreation center

4
Characteristics of the Problem
 Cardiovascular Disease (CVD) in America
 61.8 Million Americans with a CVD1
 945,836 Americans die each year from CVDs1
 Patients who participate in Phase III are 20-30%
less likely to die as a result of cardiac issues2
 Phase III participation generally ranges between
10-20%3
 Low rate of Phase III participation generally attributed to lack of motivation
and knowledge

Stanford Study1
Control Group n = 300
Standard procedures for phase III
patients
Assumed normal dropout rates

Characteristics of a Solution
 Motivates Individuals to Continue Rehabilitation
 Monitors Patient’s Blood Pressure and Heart
Rate
 Alerts User of Bad Readings
 Check-up Phone Calls to Motivate Those with Bad
Readings
 From P3C Technician
 From Patient’s Doctor
 Initial Solution
 CS410 – Phase 0

Proposed Solution
 The P3C Communicator
 P3C Heart Rate / Blood Pressure Monitor
 Captures data with automatic and manual readings
 P3C Docking Station
 Downloads data from the P3C Heart Rate / Blood Pressure Monitor
 Transmits data to P3C Central Server
 Displays responses from P3C Central Server
 P3C Central Server
 Analyses user’s blood pressure and heart rate readings
 Transmits Response to P3C Docking Station

Analysis Algorithm
 Checks Current Values Against
 Accepted Norms
 Historical Data from the User
 Allows for Personalized Analysis
 Historical Data May Vary Slightly from Norms
 Values Outside Historical Data but Inside Norms
 Could Indicate Something Wrong

 Captures Needed Data
 Omron HEM-637IT Connects to Computer
 Palm m100
 Shows Connection from Remote Device to Computer
 Two Personal Computers
 P3C Docking Station
 Download and Transmit Data

Challenges
 Hardware Development
 Shrinking the Technology
 Use Arm Cuff and ABPM instead of Wrist Cuff
 Accuracy
 Must Hold Wrist Cuff Monitor at Heart Level
 Bad Analysis
 False Positives

Conclusions
 Large Market for Product
 61.8 Million Americans with a CVD1
 Good Benefits of Use
 20-30% Less Likely to Die as a Result of Cardiac
Issues2
 Our Low Cost, Easy to Use Solution Should Be
Developed
