In this episode, we break down non-invasive fluid assessment at the bedside, focusing on IVC ultrasound, VExUS (Venous Excess Ultrasound Score), and the passive leg raise (PLR).

We walk through how to evaluate fluid responsiveness vs fluid tolerance, when each tool works (and when it fails), and how to integrate these approaches into a practical, physiology-based framework for critically ill patients.

This episode tackles one of the most common and challenging decisions in critical care: when to give fluids—and when to stop. By combining ultrasound-based assessment with dynamic testing like the passive leg raise, we outline a more complete approach to hemodynamic assessment in the ICU and emergency department.

If you’re a clinician managing acutely ill patients, this episode will help you move beyond guesswork and toward more precise, bedside-driven fluid decision-making.

In this episode, we break down ventilator-induced lung injury (VILI) and how mechanical ventilation can contribute to lung damage in critically ill patients.

We walk through the core mechanisms of VILI—including volutrauma, barotrauma, atelectrauma, and biotrauma—and then build a deeper understanding using the concepts of driving pressure and mechanical power. These frameworks help connect individual ventilator settings to the total energy delivered to the lungs and the risk of injury.

This episode focuses on a key shift in thinking: moving beyond isolated ventilator parameters toward a more integrated, physiology-based approach to lung-protective ventilation at the bedside.

If you manage ventilated patients in the ICU or emergency department, this will help you better understand why lung injury occurs—and how to minimize it.

In this episode, we break down sickle cell crisis and life-threatening complications, including vaso-occlusive crisis (VOC), acute chest syndrome (ACS), splenic sequestration, aplastic crisis, and infection.

We walk through the underlying pathophysiology of sickle cell disease, why these emergencies occur, and how to recognize and manage them in the emergency department and ICU. This is a high-yield, practical framework to help you quickly distinguish common presentations from life-threatening complications.

If you’re a medical student, resident, nurse, or practicing clinician, this episode will help you build a clear mental model for approaching sickle cell emergencies at the bedside.

In this episode, we break down how to assess fluid status at the bedside using IVC ultrasound and VExUS (Venous Excess Ultrasound Score).

We walk through how to interpret IVC diameter and collapsibility, when it works (and when it doesn’t), and how VExUS expands your assessment by integrating hepatic vein, portal vein, and renal venous Doppler to evaluate venous congestion and fluid tolerance.

This episode focuses on one of the most important clinical challenges in critical care: determining fluid responsiveness vs fluid overload. We outline a practical, physiology-based framework you can apply immediately in the ICU and emergency department.

If you’ve ever struggled with deciding when to give fluids—or when to stop—this episode will help you move toward a more complete and clinically useful approach to hemodynamic assessment.

In this episode, we break down mechanical power in mechanical ventilation and its role in ventilator-induced lung injury (VILI).

We walk through how ventilator settings—including tidal volume, respiratory rate, PEEP, and driving pressure—combine to deliver energy to the lungs, and why thinking in terms of total energy delivery may be key to preventing lung injury in critically ill patients.

Rather than focusing on individual ventilator settings in isolation, this episode provides a framework for understanding how these variables interact and how to apply this knowledge to optimize lung-protective ventilation at the bedside.

If you manage ventilated patients in the ICU or emergency department, this is an essential concept that connects physiology to real-world clinical decision-making.

TEG and ROTEM (viscoelastic testing) can fundamentally change how we approach coagulation — but only if we understand how to interpret them and act on the results.

In this episode, we break down viscoelastic testing from the ground up, then walk step-by-step through how to choose the right blood product based on real physiology — not guesswork.

We cover:

This episode is designed for medical students, residents, fellows, nurses, respiratory therapists, and practicing clinicians looking to build a clear, high-yield understanding of coagulation management in the ICU and ED.

Vasopressin is often thought of as just a “second-line pressor” — but its physiology and clinical applications are far more nuanced.

In this episode, we break down vasopressin from the ground up, starting with receptor-level physiology and how it differs from catecholamines, then build into a focused deep dive on one of its most important uses: right ventricular (RV) failure and pulmonary hypertension.

We cover:

This episode is designed for medical students, residents, fellows, nurses, respiratory therapists, and practicing clinicians looking to better understand vasopressor selection in emergency and critical care.

In this episode, we break down VExUS ultrasound (Venous Excess Ultrasound Score) and how to assess venous congestion at the bedside in critically ill patients.

We walk through the physiology of venous congestion and how to integrate IVC ultrasound, hepatic vein Doppler, portal vein Doppler, and renal venous Doppler into a practical framework for evaluating fluid tolerance vs fluid overload. This is a powerful tool for clinicians managing patients in the ICU and emergency department who are trying to decide when to give fluids—and when to stop.

If you’ve ever struggled with fluid status assessment, this episode will help you move beyond isolated measurements and toward a more comprehensive, physiology-based approach.

Viscoelastic testing with TEG (thromboelastography) and ROTEM (rotational thromboelastometry) is changing how we approach coagulopathy, bleeding, and massive transfusion in the ICU and trauma setting.

In this episode, we break down TEG and ROTEM in a simple, practical way so you can confidently interpret results and apply them at the bedside.

Stress ulcer prophylaxis is one of the most common interventions in the ICU — but also one of the most overused and misunderstood.

In this episode, we break down when stress ulcer prophylaxis is actually indicated, what medications to use, and what the evidence really shows so you can make better bedside decisions.

We cover:

Current evidence suggests stress ulcer prophylaxis should be targeted to high-risk patients rather than applied universally, with discontinuation once risk factors resolve.

This episode is part of our emergency critical care series focused on making ICU pharmacology and physiology simple, practical, and clinically applicable.
