Module Overview

Module Description

This module aims to describe key concepts in biomedical instrumentation by means of examples drawn from the area of critical care monitoring. In particular, devices and techniques used clinically to monitor oxygen delivery to tissues are explained and used to highlight basic instrumentation principles in electronics and signal processing. The lectures are supported by two 3-hour lab-classes, which use the Powerlab (R) system to illustrate physiological monitoring techniques.


Module Syllabus

Biochemical basis of oxygen consumption.
Passive and active oxygen transport via the circulation.
Physiological origin of bioelectric phenomena in nerve and muscle.
Detection via bioelectrodes.
Signal conditioning and input amplifier designs.
Origin and quantification of noise in the clinic.
SNR improvement by signal processing.
Frontal plane and 12-lead ECG.
Electrostimulation.
Respiratory monitoring.
Harmonic synchronous detection.
The Discrete Fourier Transform.
Quantitative measurements of lung function.
Physiological pressure measurement.
Flow measurement.
Doppler ultrasound flowmetry.
Clinical implementation of Doppler ultrasound.
Oximetry.
