This is a two part podcast with Dr. Daved VanStralen discussing the topic of evidence based medicine and TCCC. We have taught and "preached" TCCC for over a decade, while defending the guidelines, equipment, and recommendations with the "mantra" evidence-based medicine. After years of unexplained failures and issues, we take a look at what "EBM" actually is, and whether its performance parameters are relevant to your operational parameters.
