Overview

Hemodynamic profile aids in classification of shock and is also valuable in directing fluid therapy in patients with cardiogenic shock.

Hemodynamic Profile

Classification of shock based on hemodynamic parameters. (CO, cardiac output; CVP; central venous pressure; PAD, pulmonary artery diastolic pressure; PAS, pulmonary artery systolic pressure; RVD, right ventricular diastolic pressure; RVS, right ventricular systolic pressure; SVO2, systemic venous oxygen saturation; SVR, systemic vascular resistance.)
