#200 Eight Common Ventilator Mistakes To Avoid That May Harm Patients!

Mechanical ventilation saves lives — but small ventilator mistakes can cause major patient harm.
In this episode, we break down 8 common ventilator mistakes that clinicians frequently make in the ICU and emergency department, and explain why they matter physiologically. We cover errors related to tidal volume, PEEP, oxygenation vs ventilation, respiratory rate, patient–ventilator dyssynchrony, hemodynamics, and more — all through a clinically practical, physiology-focused lens.
📌 Topics include: Lung-protective ventilation mistakes Over-oxygenation and oxygen toxicity Mismanagement of PEEP and compliance Ventilator settings that worsen hemodynamics Missed patient–ventilator dyssynchrony Common ICU and ED ventilator pitfalls

#199 PEEP Explained: Oxygenation, Compliance & Hemodynamics

Positive end-expiratory pressure (PEEP) is one of the most powerful — and misunderstood — tools in mechanical ventilation. In this episode, we break down how PEEP works, why it improves oxygenation, and when it can actually harm patients.
We’ll walk through: • How PEEP recruits alveoli and improves oxygenation • The relationship between PEEP, lung compliance, and overdistension • How excessive PEEP affects venous return, cardiac output, and blood pressure • The concept of optimal PEEP and how to think about titration at the bedside • Common mistakes clinicians make when setting PEEP

#198 Occult Cardiogenic Shock Explained | The Shock You’re Missing at the Bedside

Occult cardiogenic shock is one of the most commonly missed shock states in Emergency Medicine and Critical Care. These patients may appear “stable” — with near-normal blood pressure — yet have severe cardiac dysfunction, low cardiac output, and poor tissue perfusion.
In this episode, we break down: 🔹 What occult cardiogenic shock actually is 🔹 Why blood pressure alone is misleading 🔹 The underlying physiology of low cardiac output shock 🔹 How to recognize occult cardiogenic shock at the bedside 🔹 The role of bedside ultrasound, lactate, ScvO₂, and clinical clues 🔹 Practical management principles in the ED and ICU

#197 Comparing Shock States | Hypovolemic vs Cardiogenic vs Distributive vs Obstructive

Shock is a life-threatening condition encountered daily in Emergency Medicine, Critical Care, and the ICU — yet it’s often taught in fragmented algorithms rather than unified physiology.
In this episode, we break down all major shock states in a clear, structured way:
🔹 Hypovolemic shock
🔹 Cardiogenic shock
🔹 Obstructive shock
🔹 Distributive shock (septic, anaphylactic, neurogenic)

#195 Hypovolemic Shock Explained: Physiology & Hemorrhagic Shock Deep Dive

Hypovolemic shock is a life-threatening condition caused by a critical reduction in intravascular volume, leading to decreased preload, reduced cardiac output, and impaired tissue perfusion. One of the most severe and common forms is hemorrhagic shock.
In this episode, we begin with a high-yield overview of hypovolemic shock, reviewing core physiology, compensatory mechanisms, hemodynamic patterns, and bedside differentiation from other shock states.
We then transition into a deep dive on hemorrhagic shock, including causes such as trauma and gastrointestinal bleeding, classic clinical presentation, laboratory and point-of-care findings, and the pathophysiologic cascade leading to the lethal triad of acidosis, hypothermia, and coagulopathy.
Management strategies are discussed in detail, including early hemorrhage control, massive transfusion protocols, balanced blood product resuscitation, permissive hypotension, tranexamic acid, calcium replacement, and key ATLS principles. Landmark trials including CRASH-2 and PROPPR are incorporated to support evidence-based care.

#192 Heart Failure & Cardiogenic Shock Explained | Pathophysiology, Diagnosis, Management

Heart failure and cardiogenic shock exist on the same disease spectrum, yet they’re often taught separately. In this episode, we bring them together into a single, cohesive framework that explains how heart failure progresses to cardiogenic shock — and how to manage both at the bedside.
Topics covered include: • Heart failure pathophysiology (HFrEF vs HFpEF) • Preload, afterload, contractility, and cardiac output • Compensated vs decompensated heart failure • Acute decompensated heart failure • Cardiogenic shock physiology • Clinical findings and hemodynamics • Diagnostic approach (exam, labs, echo, ultrasound) • Management principles and common pitfalls

#191 Mechanical Ventilation Basics - PEEP, FiO2, Respiratory Rate, Tidal Volume | Clinical Medicine

Mechanical ventilation has many different modes and settings. In this video we dive into the foundational settings that everyone should know - PEEP, FiO2, Respiratory Rate, Tidal Volume, and Inspiratory Pressure. We touch on how these settings may differ between modes of ventilation, such as volume control and pressure control. We talk about normal values and ranges of values. We also discuss which settings help ventilation versus oxygenation. Start to master these topics in this episode!
