In this episode of The Inflection Point, we sit down with Dr. Dick Zoutman, a professor at Queen’s University, Faculty of Health Sciences, to unpack the science behind N95 masks, airborne transmission, and respiratory protection.
Dr. Zoutman explains how N95 respirators, originally designed for heavy-industry applications, became essential tools in preventing airborne disease transmission. We explore the mechanics of filtration, aerosol physics, why mask fit matters, and how ventilation, air filtration, and UV-C disinfection can dramatically reduce spread in healthcare, paramedicine, and other high-risk environments.
This conversation provides clear, evidence-based guidance for paramedics, healthcare providers, system leaders, and infection-prevention professionals seeking to strengthen respiratory safety, improve indoor air quality, and better protect vulnerable populations.
The Inflection Point explores emergency medicine, paramedicine, leadership, system design, and health quality through expert interviews and practical insights.
