Paramedic training is over, you’re in the front seat now. Whether day 1 or day 1,000 you can’t shake the fear you’re underprepared. You were taught to systematically decide if A... do B. But what if “A” wasn’t in the book? The truth is each emergency call is too unique to teach the right response to every situation. We need to go beyond algorithmic thinking and understand deeper principles, the WHY behind the algorithm. When every decision counts you want to rely on a framework that will guide you when things don’t make sense. Loud & Clear: EMS Guiding Principles is your resource to build that framework. Through discussions with experts, review of evidence-based best practices, and real-world case studies we teach you one step past what you learned in paramedic school. But all of this advanced education is connected back to the guiding principles that answer the question- “at the end of the day, what actually matters to the patient I have in front of me?” Our mission is to elevate your practice and help you improve patient outcomes in every emergency situation. You may not feel ready, you may not feel like you know enough, but by understanding the guiding principles of emergency medicine you can become an expert EMS clinician. Because what you do matters.

What differentiates heat stroke from heat exhaustion? Once central nervous system dysfunction appears, every minute spent at an elevated core temperature increases the risk of permanent neurologic injury or death.
Ross and Will talk with emergency physician and wilderness medicine specialist Dr. Greg Doctor about the full spectrum of heat-related illness – from heat cramps, rash, and edema to syncope, exhaustion, and life-threatening heat stroke.
They discuss how to avoid anchoring on the heat when a patient loses consciousness and what the critical dividing line between heat exhaustion and heat stroke is.
They also examine exercise-associated hyponatremia, drug-related hyperthermia, fluid selection, and the patients who may remain at risk even after they initially appear to recover.
In this episode, you’ll learn:
- How to distinguish heat syncope, heat exhaustion, and heat stroke
- Why central nervous system dysfunction and an elevated core temperature matter most
- How to choose between cold-water immersion, continuous water and fanning, ice sheets, and ice-water slurry techniques
- When transport should be delayed for on-scene cooling, and when cooling should continue
