Obstructive Shock Explained: PE, Tamponade, Tension Pneumothorax | Emergency Critical Care

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.

Playlist on Shock:
   • Shock  

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.

⏱️ What You’ll Learn
What defines obstructive shock and how it differs from other shock states
Key hemodynamic patterns (CO, SVR, CVP, MAP)
High-yield clinical findings (Beck’s triad, RV strain, tracheal deviation)
Role of POCUS in rapid diagnosis
Definitive treatments for:
Massive PE
Cardiac tamponade
Tension pneumothorax
Board-style practice questions with explanations

This video is designed for medical students, residents, fellows, nurses, respiratory therapists, and critical care providers who want a clear, high-yield framework for mastering shock states in real clinical practice.
