Final Examination  4 January 2013  12.00-14.00
1. What instruments (signal generator, multimeter, oscilloscope, etc) would you use and how
would you design measurements to measure dynamic properties of a biomedical
measurement system? Which properties would you measure? Why? (15 points)
2. Name the main 2-3 interfering or modifying inputs to equipment in a hospital environment.
How can you minimize them? (6 points)
3. Correlate heart sounds with electrical and mechanical events of the cardiac cycle on a diagram
showing time evolution of (i) aortic and (ii) left ventricular blood pressures, (iii) EKG signal and
(iv) the heart sounds (at least the major two!). (12 points)
4. Compare and contrast macroshock vs. microshock in terms of electrical hazards in a clinical
environment. (4 sentences max.) (4 points)
5. Explain within 5 sentences the function of driven-right-leg circuit. (5 points)
6. Assume you are a staff biomedical engineer in a fully equipped hospital. One day, a patient
with acute severe headache is brought into the emergency room. You are informed that the
patient has inhaled an unknown gas that may be toxic in high concentrations. There are no
doctors around and you are called to take charge of the situation. What would you monitor,
what action(s) would you take, why? (15 points)
7. What is an instrumentation amplifier? Which bio-electrical signals are monitored best using an
instrumentation amplifier? Why? (10 points)
From your PROJECTS: (3 points each, 33 points total)
