Cardiogenic shock is a life-threatening form of shock caused by primary cardiac pump failure, leading to severely reduced cardiac output despite adequate intravascular volume.

In this episode, we break down the physiology of cardiogenic shock, classic clinical presentations, hemodynamic patterns, and evidence-based management strategies. Major causes including acute myocardial infarction, arrhythmias, acute valvular failure, and cardiomyopathies are reviewed, along with practical bedside management pearls.

We also cover mechanical circulatory support options (IABP, Impella, VA-ECMO), vasoactive medications, and landmark trials including the SHOCK Trial, IABP-SHOCK II, and CULPRIT-SHOCK.

Obstructive shock is a life-threatening form of circulatory failure caused by mechanical obstruction to cardiac filling or outflow, leading to decreased cardiac output and tissue hypoperfusion.

In this episode, we walk through obstructive shock physiology, classic clinical presentations, hemodynamic patterns, and high-yield management strategies for the most important causes: massive pulmonary embolism, cardiac tamponade, and tension pneumothorax.

We also highlight how bedside ultrasound (POCUS) can rapidly differentiate types of obstructive shock and guide definitive, life-saving interventions in the emergency department and ICU.

Hypovolemic shock is a life-threatening condition caused by loss of intravascular volume, leading to decreased preload, reduced cardiac output, and impaired tissue perfusion. In this episode, we break down hypovolemic shock from first principles, focusing on physiology, hemodynamics, clinical presentation, and evidence-based management.

Distributive shock is one of the most important shock states to recognize in emergency and critical care medicine. In this high-yield breakdown, we cover pathophysiology, clinical presentation, hemodynamics, and evidence-based management — including sepsis, anaphylaxis, and neurogenic shock.

You’ll learn: ↓ SVR and “relative hypovolemia” Warm shock vs late cold shock progression Hyperdynamic cardiac output in early sepsis Neurogenic shock and bradycardia When to use fluids vs vasopressors Norepinephrine as first-line pressor When to add vasopressin or steroids Key trials: EGDT, ProCESS, ARISE, ProMISe, VASST, SOAP II, ADRENAL, APROCCHSS.

Management pearls: Fluids + antibiotics early in septic shock IM epinephrine first-line for anaphylaxis Phenylephrine or norepinephrine in neurogenic shock MAP ≥ 65 mmHg, lactate clearance, urine output targets
