On today’s podcast we continue our 5-part series on Attacking Breath Testing. In this second part of this series, the NC DWI Guy does of a deep dive into the EC/IR II breath testing machine with expert witness and board certified toxicologist Dr. Andy Ewens.
Dr. Ewens was on Episode 59 (the first episode of this five-part series) to discuss the science of breath testing, so take a listen to that episode before listening in to today’s conversation. Dr. Ewens has a PhD in pharmacology and has spent 15 years as a government contract toxicologist. He has conducted a number of studies and experiments on the EC/IR II (which he owns). He provides expert case evaluation through his consulting company, Ewens Toxicology Consulting, LLC.
Hear Dr. Ewens talk about the difficulties he went through in getting his EC/IR II and why science is underserved when access to machines used for breath testing is not made readily available.
Gain insight into some of the experiments that Dr. Ewens has conducted with his EC/IR II and the breath results reported related to these experiments.
Understand how the EC/IR II functions and the role of a fuel cell (EC) and infrared light (IR) in breath testing.
Discover some of the biggest concerns that Dr. Ewens has with the EC/IR II and how to effectively use expert witness testimony in drawing these issues to light with a jury.
