WhiteBoard Medicine - Emergency And Critical Care

Respiratory failure is one of the most common and high-stakes problems in emergency and critical care medicine — but understanding the different types can be confusing.

In this episode, we break down Type 1–4 respiratory failure into a simple, structured framework you can actually use at the bedside. We focus on the key distinction between hypoxemic vs hypercapnic respiratory failure, how to interpret ABGs, and how to recognize the underlying physiology driving each type.

Whether you're a medical student, resident, nurse, respiratory therapist, or practicing clinician, this episode is designed to help you move beyond memorization and build a practical, bedside approach to respiratory failure.

We cover:
• Type 1 respiratory failure (hypoxemic) — causes and physiology
• Type 2 respiratory failure (hypercapnic) — ventilation failure and CO₂ retention
• Type 3 respiratory failure — perioperative atelectasis and reduced lung volumes
• Type 4 respiratory failure — shock-related respiratory failure
• ABG interpretation and how to differentiate respiratory failure types
• Common ICU and ED causes including ARDS, COPD, pulmonary edema, and neuromuscular disease
• A structured framework for bedside recognition and management

Mechanical ventilation is a core skill in critical care and emergency medicine—but the ventilator can feel overwhelming when you’re first learning it.

In this episode, we break down the essential ventilator settings—PEEP, FiO₂, respiratory rate (RR), and tidal volume (TV)—in a way that’s simple, practical, and directly applicable at the bedside.

We focus on building a clear mental model of how the ventilator works, including:

What PEEP does for oxygenation and alveolar recruitment

How FiO₂ impacts oxygen delivery

How respiratory rate controls ventilation and CO₂ removal

How tidal volume relates to lung-protective ventilation

How these settings interact in real ICU and ED patients

Whether you’re a medical student, resident, nurse, respiratory therapist, or practicing clinician, this episode is designed to help you move from memorizing settings → actually understanding them.

Understanding stressed vs unstressed volume is one of the most important—and most misunderstood—concepts in hemodynamics and shock.

In this episode, we break down how venous capacitance, mean systemic filling pressure (MSFP), and venous returnactually work, and why they matter for managing critically ill patients in the ICU and emergency department.

We focus on translating physiology into practical bedside understanding, including:

What stressed and unstressed volume actually represent

How MSFP drives venous return

Why vasopressors (like norepinephrine) increase effective circulating volume

How fluids vs vasopressors impact preload differently

Applying this framework to septic shock, hemorrhagic shock, and distributive states

If you’ve ever wondered why fluids or vasopressors work (or don’t), this episode gives you the physiology behind it.

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.
