When Perfusion Fails: Understanding Types of Shock

Shock can develop quickly in the backcountry, and recognizing it early can save a life. In this episode, we focus on how to identify shock with limited tools and how to tell the difference between its major types in remote settings. We break down cardiogenic, vasogenic, and hypovolemic shock using real-world backcountry scenarios, emphasizing observable signs, mental status changes, skin findings, and simple assessments you can perform in the field. The discussion highlights how understanding the type of shock can guide priorities such as bleeding control, positioning, insulation, and evacuation decisions when definitive care is hours—or days—away.
