P16081: Circulatory System

Table of Contents

Project Objective Statement

Our goal is to deliver a functioning physical model of systemic circulation which, when used in conjunction with P16080's heart pump, will be used as a teaching tool that will allow students to validate mathematical models of the circulatory system from Chapter 5 of Quantitative Human Physiology An Introduction by Joseph Feher. The model will ultimately enhance students' understanding of the circulatory system by enabling them to analyze the circulatory system under normal, exercise, and pathological conditions through the measurement of pressure and flow.

Background

Current methods of studying the circulatory system in BIME 492: Systems Physiology Dynamics and Controls Lab are restricted in that the students themselves must act as subjects for their experiments. This method is limited in that students cannot study the circulatory system independently from the respiratory system nor can they study anything other than a normal, healthy circulatory system. A physical model of systemic circulation provides the ability for students to model both normal and pathological conditions and measure relevant outputs, such as pressure and flow. The model should be able to work together seamlessly with the P16080 heart pump project in order to create a complete working model of the entire circulatory system.

Textbook Sources

Theoretical Models

Mathematical modeling parameters (vessel compliance, vascular resistance, fluid flow,etc.) will be derived mainly from the textbooks referenced above.

Potential Component Suppliers

The overall goal is to complete the prototype within a $500 budget. In the table below is a list of the projected costs:

Other models for benchmarking:

Meetings will scheduled to assess the applicability of these in our system design. The team is currently reaching out to other schools to see how their needs are being met in terms of a circulatory model for their physiology laboratory courses.

Update: After meeting with both SMEs (Subject Matter Experts) for a demonstration of each of their model's capabilities, we have decided on keeping close ties with Dr. Day and his model. The model construction is aligned with our interests in terms of functionality and compact capabilities.

Research

Project Summary

The goal of this project is to design a model of systemic circulation which, when used in conjunction with the P16080 heart pump project, can be used as a Circulatory System Model for the BIME 492 course at RIT. The model will allow students to analyze normal and physiological conditions and the effect these various conditions have on this component of the circulatory system. The expected end result is a functional prototype that allows the user to choose a desired physiological condition to model and measure pressure and flow as an output.
