APJ ABDUL KALAM TECHNOLOGICAL UNIVERSITY

Eighth semester B.Tech degree examinations, September 2020

Course Code: BM482
Course Name: BIOMEDICAL INSTRUMENTATION

PARTA
Answer any two full questions, each carries 15 marks.
Summarize a typical cell potential waveform. Explain the electrical activity
associated due to a trigger in a polarized state.
Generalize the sources of biomedical signals.
Suggest an electrode to study the electrical activity of individual cells. Hence
explain its characteristics and classifications.
“Bioacoustic signals provide an indication of the heart rate and its rhythmicity”,
based on this concept explain the mechanical events associated?
What are the prerequisites for a transducer used in biomedical applications?
Explain photoplethysmograph.
Differentiate between Active and Passive transducers. Write short notes on any of
the transducers employed for pressure measurement.
Discuss the working of a defibrillator.
PART B
Answer any two full questions, each carries 15 marks.
What are the prerequisites for an ideal oxygenator?
Appraise the need for an infusion pump. How does it differ from a syringe pump?
Summarize Infant Incubators.
Based on respiratory parameters explain respiratory volumes.
Generalize the rhythmic patterns obtained from diagnostic equipment to
determine epilepsy.
Define evoked potential. What are its classifications?
What is meant by Lithotripsy? Prepare a short note on any two types of shock-
wave sources for lithotripsy.

With relevant schematic appraise the instrumentation setup to diagnose epilepsy.
