Wednesday Edition
Every Wednesday: the physiology that drives every intervention.
Hemodynamic instability is the most common reason patients are critically ill.

Every Wednesday, ICCN publishes a bedside summary on cardiogenic shock, RV failure, vasopressor strategy, and the hemodynamic literature that should change practice.

Most ICU decisions are hemodynamic decisions at their core. Understanding why the cardiac output is low — preload, afterload, contractility, rate, or rhythm — is the difference between intervention that helps and intervention that harms.
