Laboratory Project

Activity   Description   Due Date  
Midterm report   Report is 3-4 pages (double spaced). Describe project progress to date. Discuss any current challenges.   Mar. 1  
Presentation   Presentations will ≤10 minutes. Marks are based on technical content, clarity of presentation, and ability to answer questions.   Apr. 5 − Apr. 7  
Report   The report will be 10−20 pages (double spaced). Include an introduction, methods, results and discussion.   Apr. 5  

For the course project, students will analyse data from a medical instrumentation system. Data must be measured in raw form using a D/A converter (ie. raw ECG voltage measurements, rather than heart rate). If necessary, software must be developed to analyse the data. Data may come from any of the following sources:
− Measured at respiratory system lab
− Obtained from a biomedical database
− Measured by the student. If you wish to do this, then it will be permissible to work in groups of 2 or 3.

A list of possible project ideas (please discuss your ideas with the instructor or T.A. to get feedback on feasibility)
− measure ECG and calculate heart rate for different activities
− measure EMG and calculate gait
− measure EMG and calculate fatigue
− measure flow and calculate Flow Volume loops to get maximum expiratory flow
− build mask to simulate high expiratory resistance in asthma − calculate flow
− get blood pressure from inflated cuff
− Measure VO2,max with exercise
− Test maximum expiratory flow with negative end expiratory pressure (NEEP)
− Measure surface and core temperature changes
