In this episode, we break down how to approach acute hypoxemic respiratory failure at the bedside. You’ll learn step-by-step interpretation of arterial blood gases (ABG), venous blood gases (VBG), alveolar-arterial (Aa) gradient, and using the chest x-ray and ABG to diagnose the cause. We’ll cover the physiology, practical interpretation pearls, and common pitfalls so you can confidently apply this knowledge in the ICU, ED, or ward...

Master the fundamentals of cardiac physiology — from chamber pressures and cardiac output to preload, afterload, contractility, and the Fick equation. 🫀 This episode breaks down complex hemodynamics and devices into simple, high-yield concepts for exams and bedside care. Perfect for medical students, residents, fellows, nurses, physiologists, and clinicians in emergency medicine, critical care, and cardiology.

Master the key pressures in mechanical ventilation: peak inspiratory pressure, plateau pressure, and driving pressure. In this episode, we break down what each pressure means, how to measure them, and why they’re critical for managing patients in the ICU and emergency department. Perfect for medical students, residents, critical care fellows, respiratory therapists, emergency nurses, critical care nurse, and anyone preparing for ex...

Mechanical circulatory support (MCS) is a cornerstone of modern critical care, cardiology, and cardiac surgery. In this episode, we review the most important devices — LVADs, intra-aortic balloon pump (IABP), and ECMO — with a focus on when and how they’re used.

📌 What’s covered in this video: Basics of mechanical circulatory support (MCS). LVAD (Left Ventricular Assist Device): how it works, indications, complications, alarms, su...

In this episode, we break down the four major shock states — hypovolemic, cardiogenic, obstructive, and distributive — and provide a structured approach to evaluating patients in undifferentiated shock. We’ll then take a deeper dive into septic shock, including pathophysiology, diagnosis, and management strategies used in the ICU and emergency department.

End tidal capnography (ETCO₂) is one of the most important tools in emergency medicine, anesthesia, and critical care. In this episode, we break down normal and abnormal capnography waveforms, explain the physiology behind each pattern, and show you how to apply ETCO₂ in real clinical scenarios.

📌 What’s covered in this video: Normal ETCO₂ waveform and interpretation. Obstructive patterns (bronchospasm, airway obstruction). The “c...

Calcium channel blocker (CCB) overdose is one of the most dangerous toxicologic emergencies seen in emergency medicine and critical care.
