This discussion covers: What cryoprecipitate is and what it contains Indications for cryoprecipi

#218 Platelet Transfusion Explained | Indications, Thresholds, and Transfusion Triggers Feb 12, 2026 987 Platelet transfusion is a common intervention in thrombocytopenia, bleeding, and peri-procedural care — but knowing when to transfuse, what thresholds to use, and how to balance risks and benefits is critical. In this episode, we walk through a practical, evidence-based approach to platelet transfusion decision-making, focusing on real-world clinical scenarios rather than slide-based teaching. Top

#217 Prothrombin Complex Concentrate (PCC) Explained | Components, Indications, Dosing, and Safety Feb 10, 2026 993 Prothrombin Complex Concentrate (PCC) is a powerful, targeted coagulation therapy used in urgent bleeding and anticoagulation reversal. In this episode, we walk through what PCC is, when to use it, how to dose it, and what safety considerations matter most in real-world clinical practice. This audio-focused discussion covers: What Prothrombin Complex Concentrate (PCC) contains Common indicatio

#216 Shock Explained: An ICU Starter Guide to Physiology, Vasopressors, and Management Feb 8, 2026 6649 Shock is a life-threatening state of circulatory failure that requires rapid recognition and a strong understanding of underlying physiology. In this episode, we provide a clear, structured ICU starter guide to shock, focusing on how and why patients deteriorate and how to intervene effectively at the bedside. We begin with the core physiology of shock and mechanisms of impaired tissue perfusion,

#215 Septic Shock Explained: Diagnosis, Management, and Common Mistakes Feb 6, 2026 2743 Septic shock is one of the most common and deadly emergencies encountered in critical care, yet early missteps in diagnosis and management can dramatically worsen outcomes. In this episode, we walk through septic shock step by step, focusing on how to recognize it, how to manage it effectively, and the most common mistakes clinicians make along the way. We start by reviewing the physiology of sept

#214 ECMO Explained: VA-ECMO, VV-ECMO, and When to Use Each Feb 4, 2026 3337 Extracorporeal membrane oxygenation (ECMO) is one of the most complex and powerful tools in critical care—but also one of the most misunderstood. In this episode, we break down ECMO step by step, focusing on VA-ECMO, VV-ECMO, how they work, and when to use each configuration. We start with the fundamentals of ECMO physiology and circuit components, then walk through veno-arterial (VA) ECMO for car

#213 Most Common Mistakes in Septic Shock Management | Emergency & Critical Care Feb 2, 2026 1319 Septic shock management is complex, and many poor outcomes stem from preventable management errors rather than delayed recognition. In this episode, we break down the most common mistakes clinicians make when managing septic shock, using a physiology-driven framework relevant to both the emergency department and ICU. We discuss pitfalls related to fluid resuscitation, delayed or inappropriate vaso

#212 Metformin-Associated Lactic Acidosis (MALA) Explained | Symptoms, Pathophys, Diagnosis & Management Jan 30, 2026 893 Metformin-associated lactic acidosis (MALA) is rare, but when it occurs, it carries significant morbidity and mortality. In this episode, we walk through a practical, clinician-focused approach to recognizing and managing MALA in the emergency department and ICU. We review the pathophysiology behind metformin-related lactic acidosis, common risk factors and precipitating conditions, and the clinic

#211 Four Common Mistakes in Shock Management | Emergency & Critical Care Jan 28, 2026 1140 Shock management is where small clinical decisions can have outsized consequences. In this episode, we break down four common mistakes clinicians make when managing patients in shock, with a focus on physiology-driven decision making rather than protocol-only care. We discuss the consequences of ignoring right ventricular failure, delaying vasopressors, treating mean arterial pressure instead of t

#210 VV-ECMO Explained in Under 10 Minutes | Anatomy, Components, & Settings Jan 26, 2026 654 Veno-venous ECMO (VV-ECMO) is primarily a respiratory support modality, but its physiology is often oversimplified. In this episode, we walk through VV-ECMO from a practical, clinician-focused perspective. We discuss what VV-ECMO is, how the circuit is configured, key anatomic considerations for cannulation, and the core components of the system. We also review common VV-ECMO settings and how chan

#209 VA-ECMO Explained in Under 10 Minutes | Anatomy, Components, & Settings Jan 24, 2026 669 VA-ECMO explained in under 10 minutes. We cover what VA-ECMO is, vascular anatomy and cannulation, core circuit components, and key ECMO settings used in emergency and critical care medicine. In this episode, we break down: What veno-arterial ECMO (VA-ECMO) is and when it’s used Anatomy & cannulation strategy (venous drainage, arterial return) Core VA-ECMO components (cannulae, pump, oxygenato
