Project Overview

Magnetic resonance imaging can be used to study pulmonary blood flow in hypertensive patients before and after exercise. The goal of this project is to create a device which will be used to exercise subjects to 40% of a predetermined maximal workload in both healthy subjects and patients with hypertension. A preliminary cycling device was constructed and tested via Doppler Ultrasound and found to increase the pulmonary systolic pressure an average of 5.54 mmHg. This pressure increase was determined using the modified Bernoulli equation with the tricuspid regurgitant velocity. Future work entails doing MRI testing and building a final device that is milled out of solid sheets of HDPE.
