Impedance Cardiography Clients: Prof. John Webster Elena S. Bezrukova Team Members: Jacob Meyer (Leader) David Schreier (Communicator) Tian Zhou (BSAC) Ross Comer (BWIG) April 1 to April 8 Project Statement: Impedance Cardiography is a non-invasive medical procedure utilized in order to properly analyze and depict the flow of blood through the body. With this technique, four electrodes are attached to the body—two on the neck and two on the chest—which take beat by beat measurements of blood volume and velocity changes in the aorta. However, our client hypothesizes that the current method withholds degrees of inaccuracy due to the mere fact that the electrodes are placed too far from the heart. Our collective goal is to design an accurate, reusable, spatially specific system that ensures more accurate and reliable cardiographic readings. Furthermore, this system must produce consistent results able to be accurately interpreted by industry professionals. Initial Design Goals: • Prepare Final Poster • Discuss future work with client Project Status Summary: This past week we worked on our poster and organized for our presentation on Friday. We also discussed future work, and determined that we will in fact be spending an extra week oncampus. We will concentrate on soldering our circuitry and taking more measurements. We will also be applying to the IRB for human testing in the fall. We are excited to continue our work. Future Design Expectations: • Collect more measurements Work Hours: Name Work Performed No. of Hours/Task Total Hours Jacob Meyer Progress Report Team meeting Independent work 1 hr 6 hr 3 hr 10 hrs David Schreier Communication Team Meeting Independent Research ½ hr 6 hr 5 hr 11 ½ hr Tian Zhou BSAC meeting Team Meeting 1 hr 7 hr 8 hr Ross Comer Team Meeting Website update 6 hr ½ hr 6 ½ hr Team 36
