Conducted electrical weapons

police cars 300 x 178AFSF
Dr. Jauchem has served as expert witness in Texas and Louisiana for plaintiffs in cases involving use-of-force incidents in which conducted electrical weapons were used. Along with conducted electrical weapons, Dr. Jauchem has studied specific areas relevant to forensic pathophysiology, including excited delirium, hyperthermia, and proteomics.

Measurements of physiological factors prior to final pathological findings can help to develop hypotheses relating to weapons effects. One of the strengths of using laboratory models is the ability to control confounding factors. Dr. Jauchem selected the model he used for blood-factor studies for several reasons, including similarities to humans in terms of chemical and physical characteristics of blood, respiratory parameters, and responses to muscular exercise.
