Cardiac & Hemodynamics
Every Wednesday: the physiology that drives every intervention.
Hemodynamic instability is the most common reason patients are critically ill. The vasopressor you choose, the fluid you give (or don’t), and the right ventricle you forgot to assess shape every other decision. Every Wednesday, ICCN publishes a bedside summary on cardiogenic shock, RV failure, vasopressor strategy, and the hemodynamic literature that should change practice.

Why Wednesdays matter.
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.
