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: V1, V2, and V3 receptor physiology How vasopressin affects systemic vs pulmonary vascular tone Differences from norepinephrine and other vasopressors Why vasopressin can be uniquely helpful in RV failure Practical bedside considerations in shock states 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. 🎯 Want the full breakdown?
