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

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

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

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
