Aims: This course aims to provide an understanding of biopotentials and other biological signals, and identify mechanisms by which they can be measured. It also aims to provide a detailed understanding of the fundamental principals associated with transducers, and comprehensive review of the most widely used techniques for the diagnosis and treatment of disease states
Objectives: Upon completing this course, students will have attained:

Knowledge of biocompatibility & safety requirements of instrumentation in clinical practise

An understanding of the generic complications of measuring physiologically relevant parameters and how these can be overcome.

Knowledge of a wide range of biomedical transducers and techniques for collecting and displaying signals, with particular reference to respiratory and cardiovascular systems.

An understanding of the derivation of various bioelectric potentials from the body and appropriate techniques for measuring and analysing these signals.
Syllabus: 1. Use of transducers in a medical environment: environment & safety requirements (1 hr).
2. Sensors for medical applications: Pressure, force, position, temperature, flow, velocity, volume, chemicals (1 hr).
3. Cardiovascular measurements – invasive& non invasive BP monitoring (4 hrs).
4. Respiration measurements – lung function & whole body plethysmography (4 hrs).
5. The origin & nature of biopotentials – nerves and resting & action potential (2 hrs)
6. Recording biopotentials: EEG, EMG, ECG (7 hrs)
7. Stimulators for the cardiac system: pacemakers and defibrillators (3 hrs)
8. Electrical stimulation: response to stimuli and use of stimulators (1 hrs)
