CHF Companion

Smart Home Monitoring for Heart Failure Patients

CHF Companion is an individual Computer Science Capstone Project exploring the design and development of a mobile health application for home monitoring of patients living with congestive heart failure.

The application combines automated weight and blood pressure collection, longitudinal health tracking, an observation diary, and structured reporting for healthcare consultations.

The Challenge

Managing Heart Failure at Home Is Difficult

Heart failure requires consistent monitoring between healthcare visits. Weight and blood pressure measurements, together with information about symptoms and daily observations, can provide important context for understanding changes in a patient's condition.

6.7 Million
Americans living with heart failure
11.4 Million
Projected prevalence by 2050
Hospitalization
A leading cause among older adults
01

Patient

Daily measurements, symptoms, and observations.

02

Between Visits

Information may be kept in paper notes or fragmented records.

03

Clinician

Limited longitudinal context may be available during consultation.

Inconsistent tracking and fragmented information can make it difficult to understand how a patient's condition changes over time.

The project explores how technology can make daily monitoring more structured, connected, and accessible.

Project Goal

Designing a Better Approach to Home Monitoring

The goal of CHF Companion is to design and develop a mobile application that enables patients with congestive heart failure to monitor weight and blood pressure, automatically synchronize measurements from compatible smart devices, visualize long-term trends, maintain an observation diary, and generate structured reports for healthcare professionals.

The Solution

CHF Companion

CHF Companion brings measurements, observations, historical trends, and reporting together in a single mobile application designed to support structured home monitoring.

Automatic Data Collection

Weight and blood pressure measurements are synchronized from compatible smart medical devices through vendor integrations.

Longitudinal Trends

Historical measurements are organized and visualized to help users understand changes over time.

Observation Diary

Users can record contextual observations alongside objective measurements.

Structured Reports

Measurement history, charts, statistics, and observations can be compiled into reports for healthcare consultations.

Caregiver Support

The application supports family caregivers who assist patients with monitoring and reviewing health information.

Who We Designed For

Supporting Patients and the People Who Help Them

CHF Companion is designed for two primary user groups who work together to support consistent home monitoring.

Independent Patients

Older adults living independently with heart failure who need a simple and accessible way to review their health information at home.

Primary needs: automatic measurement collection, clear trends, simple navigation, and easy access to health history.

Family Caregivers

Family members or patient assistants who support daily monitoring when a patient needs additional help using the application.

Primary needs: access to monitoring information, straightforward workflows, and a clear view of measurements and observations.

Project Status

From System Design to Working Prototype

CHF Companion is currently in the prototype development phase. The core system architecture, application design, and primary mobile workflows have been established, with implementation and integration work continuing toward the final Capstone release.

System Design

Completed / Evolving

Core architecture, services, interfaces, data models, and the integration approach have been defined.

Mobile Application

Prototype Available

Core application workflows and the user interface have been implemented, with further development and integration continuing.

Backend & Integrations

In Development

Backend services and external integrations are being implemented and validated against the system design.

Testing & Deployment

Upcoming

Integration testing, prototype validation, deployment, and final project review will follow implementation.
