WhiteBoard Medicine - Emergency And Critical Care

In this episode, we explore the different phenotypes of Acute Respiratory Distress Syndrome (ARDS), with a focus on severity, clinical, biomarker, and physiologically derived phenotypes. We dive into hyper inflammatory and hypo inflammatory phenotypes including their morbidity, mortality, and management differences. ARDS is a critical condition that requires timely and precise intervention to improve patient outcomes. Whether you're a healthcare professional, a medical student, or someone interested in respiratory care, this video provides an in-depth analysis of the best practices and latest research in ARDS phenotypes.

Endocrine shock refers to life-threatening shock states caused by hormonal deficiencies or endocrine crises that impair vascular tone, cardiac output, and metabolism. Unlike other forms of shock, endocrine shock is often diagnosed only after common causes such as sepsis, cardiogenic, or hypovolemic shock have been ruled out.
In this episode, we break down the pathophysiology, clinical presentation, and hemodynamic patterns of the most important endocrine emergencies: adrenal crisis, myxedema coma, thyroid storm, and severe hypoglycemia. We focus on recognition of key clues such as refractory hypotension, bradycardia, hypothermia, electrolyte abnormalities, and metabolic collapse.
Management principles including IV hydrocortisone for adrenal crisis, thyroid hormone replacement for myxedema coma, beta-blockade and thionamides for thyroid storm, and dextrose for hypoglycemia are reviewed alongside guideline-based recommendations. This video is designed for emergency medicine, critical care, and internal medicine trainees as well as board exam preparation.

Acute Respiratory Distress Syndrome (ARDS) diagnosis can be complex, but is critically important. In this video, we dive into the complexities of diagnosing ARDS. We discuss the Berlin Criteria as a diagnostic approach before transitioning into the newer Global Definition of ARDS published in 2024. We compare and contrast these two diagnostic frameworks, review real-world examples, and discuss how to apply this clinically.

Neurogenic shock is a form of distributive shock caused by loss of sympathetic tone after spinal cord injury, most commonly with lesions above T6. Unlike other shock states, it presents with hypotension, bradycardia, and warm, dry skin.
In this episode, we break down the pathophysiology of neurogenic shock, how to distinguish it from spinal shock, classic clinical findings, and high-yield hemodynamic patterns. We also review evidence-based management including fluid strategy, vasopressor selection, bradycardia treatment, and temperature control.
Guideline-based targets for spinal cord perfusion, including AANS/CNS MAP goals, are discussed along with critical trauma and ICU pearls. This video is designed for emergency medicine, critical care, trauma, and neurology trainees as well as board exam preparation.

Cardiogenic shock is a life-threatening form of shock caused by primary cardiac pump failure, leading to severely reduced cardiac output despite adequate intravascular volume.
In this episode, we break down the physiology of cardiogenic shock, classic clinical presentations, hemodynamic patterns, and evidence-based management strategies. Major causes including acute myocardial infarction, arrhythmias, acute valvular failure, and cardiomyopathies are reviewed, along with practical bedside management pearls.
We also cover mechanical circulatory support options (IABP, Impella, VA-ECMO), vasoactive medications, and landmark trials including the SHOCK Trial, IABP-SHOCK II, and CULPRIT-SHOCK.

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.
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.
