High-Flow Nasal Cannula (HFNC) has become one of the most important respiratory support modalities in emergency medicine, critical care medicine, respiratory therapy, and hospital medicine. By delivering heated, humidified oxygen at high flow rates, HFNC can improve oxygenation, reduce work of breathing, wash out anatomic dead space, and provide a small amount of positive airway pressure. HFNC has emerged as a key tool for managing acute hypoxemic respiratory failure and is increasingly used across emergency departments, ICUs, and inpatient settings.

In this episode, we review the physiology behind HFNC, discuss how it differs from conventional oxygen therapy, and explore practical applications in acute hypoxemic respiratory failure, pneumonia, ARDS, preoxygenation, post-extubation support, and other critical care scenarios. We also discuss flow rates, FiO₂ adjustments, troubleshooting, and common pitfalls when caring for patients requiring advanced oxygen therapy.

BPAP and AVAPS are two commonly used forms of noninvasive ventilation, but understanding how they differ and when each mode may be appropriate can be challenging. While BPAP delivers fixed pressure support through preset IPAP and EPAP settings, AVAPS adds a target tidal volume and automatically adjusts inspiratory pressure support to help maintain that goal.

In this episode, we compare BPAP and AVAPS, review the physiology behind each mode, discuss practical settings, and explore common clinical applications. We also review the advantages, limitations, and troubleshooting strategies for both modalities and discuss how they are used in patients with COPD exacerbations, hypercapnic respiratory failure, obesity hypoventilation syndrome, neuromuscular disease, and other causes of ventilatory failure.

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:

• The pathophysiology of stress-related mucosal disease (SRMD) and GI bleeding
• Which ICU patients are truly high risk (shock, coagulopathy, critical illness)
• Evidence-based indications for prophylaxis vs overuse
• PPIs vs H2 blockers — mechanisms, benefits, and risks
• Potential harms including pneumonia, C. difficile, and unnecessary continuation
• When to start and stop therapy based on ICU course and risk factors

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

In this episode, we break down ICU pharmacology into three foundational domains that form the backbone of bedside critical care:

• Sedation and analgesia (propofol, fentanyl, dexmedetomidine)
• Vasopressors and inotropes (norepinephrine, vasopressin, epinephrine, dopamine, dobutamine)
• Intravenous fluids (crystalloids, colloids, and fluid resuscitation strategies in shock)

This is not a comprehensive review of all ICU medications, but a practical, physiology-driven framework to help you understand how these therapies work together in real patients.

We focus on hemodynamics, perfusion, sedation strategies, and fluid management—with an emphasis on septic shock, respiratory failure, and emergency critical care applications.
