Dr. Swanson received his DVM from The Ohio State University and is board-certified by the American College of Veterinary Anesthesiologists. At NC State he is an Associate Professor of Anesthesiology in the Department of Molecular Biomedical Sciences. His academic interest is in using heart rate spectral analysis, a noninvasive technique, to describe autonomic nervous system function and the affects of drugs on it, in a variety of species.
Research Area:
My primary
interest is in studying the affects of analgesics and anesthetics
on autonomic nervous system function in fish. Recent technological
developments enable us to wirelessly transduce electrocardiographic
(ECG) signals from conscious fish directly through the water.
I have previous experience using heart rate spectral analysis
as a means of noninvasively describing event- and drug-evoked
changes in mammalian autonomic nervous system modulation. My
intention is to similarly use power spectral analysis of fish
ECG data as a means of monitoring studying stress and pharmacodynamics
in fish.
Current
Activity:
I am finishing
the process of personally building a data collection and analysis
system in cooperation with researchers in Sweden and Denmark
who recently published a paper describing a data collection
method that improved upon those previously used for acquiring
fish ECG data non-invasively 1. The device is a cylindrical
chamber fabricated from 6 inch diameter, clear, PVC pipe. AgCl
electrodes embedded in semicircular wells formed in the pipe
are cabled to a computer based analog-digital data acquisition
and analysis system. We will be testing this system soon, debugging,
and begin using it to describe autonomic changes secondary to
handling stress and analgesics in koi fish.
