#270 Salicylate Toxicity Explained Clearly | Acid Base Disorders, Intubation Pitfalls & ICU Management

Salicylate toxicity is one of the most important acid-base and toxicologic emergencies encountered in emergency medicine, critical care, and hospital medicine. In this episode, we break down salicylate poisoning from the ground up including salicylate pharmacology, acid-base physiology, respiratory alkalosis, metabolic acidosis, sodium bicarbonate therapy, hemodialysis indications, airway management, and ICU management strategies. We also discuss: • Recognition of salicylate toxicity • Tachypnea and compensatory hyperventilation • Salicylate distribution and tissue penetration • Pulmonary edema and CNS toxicity • Volume depletion and electrolyte abnormalities • Intubation pitfalls in salicylate poisoning • Why mechanical ventilation can rapidly worsen critically ill patients • Co-ingestions and diagnostic challenges This episode is designed for medical students, residents, fellows, nurses, respiratory therapists, advanced practice providers, and practicing clinicians looking for a high-yield review of salicylate toxicity and acid-base disorders in critical illness.

#269 Opioid Toxicity Explained | Recognition, Naloxone & Critical Care Management

Opioid toxicity remains one of the most important toxicologic emergencies encountered in emergency medicine, critical care, EMS, and hospital medicine. In this episode, we break down opioid overdose from the ground up including opioid pharmacology, respiratory depression physiology, recognition of the opioid toxidrome, naloxone administration, airway management, ventilator considerations, post-reversal monitoring, and ICU management strategies. We also discuss: • Hypoventilation and hypercapnia • End tidal CO2 monitoring • Pulmonary edema in opioid overdose • Long-acting opioids and recurrent toxicity • Co-ingestions and diagnostic pitfalls • Intubation considerations in critically ill overdose patients This episode is designed for medical students, residents, fellows, nurses, respiratory therapists, advanced practice providers, and practicing clinicians looking for a high-yield review of opioid toxicity and overdose management.

#268 Frank Starling Curve and Cardiac Output - Cardiac Physiology Masterclass

The Frank-Starling curve is one of the most important concepts in cardiac physiology—and one of the most clinically useful in critical care. In this episode, we break down the Frank-Starling relationship and connect it directly to cardiac output, so you can understand how preload affects stroke volume and how this translates to real bedside decision-making. We cover: * What the Frank-Starling curve represents * How preload affects stroke volume and cardiac output * The relationship between venous return, ventricular stretch, and contractility * How to identify the steep vs plateau portions of the curve * What fluid responsiveness actually means * Clinical applications in shock, heart failure, and critical illness Whether you’re managing hypotension, shock, or complex hemodynamics, this episode provides a clear framework to understand preload responsiveness and optimize perfusion in real time. 🎥 Watch the full video version here: https://www.youtube.com/watch?v=eEWGl7OGKaM [https://www.youtube.com/watch?v=eEWGl7OGKaM] 📚 Download the full study guide + access our complete emergency critical care curriculum: https://www.patreon.com/c/WhiteBoardMedicine [https://www.patreon.com/c/WhiteBoardMedicine] Our Patreon includes: • Study guides for every video • Mini-courses (ventilation, shock, RRT & more) • Practice questions • Ad-free videos • A structured ICU curriculum Disclaimer: This content is for educational purposes only and does not constitute medical advice.
