Title: Explain the physiological basis for types of biosignals.
Course: Biomedical Engineering (21049) > Section: Exploring Medical Devices and Imaging

Explanation should include

•    physiological signals

o    blood pressure
o    blood flow
o    respiration
o    activity levels

•    biopotentials

o    electroencephalogram (EEG)
o    electromyography (EMG)
o    electrocardiogram (EKG)

•    biochemical signals

o    glucose level
o    oxygen saturation.

Process/Skill Questions:

•    How are biosignals generated?
•    How are different biosignals related to underlying health and disease?
•    How could the glucose level in a patient be influenced?
•    Why might blood pressure increase or decrease?
•    What variables might affect the rate and volume of blood flow?
