Hemodynamic Parameters in Shock

The monitoring of hemodynamic parameters is an important tool for the diagnosis of different kinds of shock, as well as the management of such cases. The table below shows the main hemodynamic characteristics of different kinds of shock:

Hypovolemic↑ (early) or ↓ (late)
- Neurogenic
- Anaphylactic
- Septic↑ or ↓
- Pulmonary embolism, tension pneumothorax
- Pericardial tamponade

PWP – Pulmonary Artery Wedge Pressure (Preload)
CO – Cardiac Output
CVP – Central Venous Pressure
SVR – Systemic vascular resistance (Afterload)
SvO2 – Mixed Venous Oxygen Saturation (From Pulmonary Artery Catheter). Cutoff is 65%.
ScvO2 – Central venous O2 saturation (From Regular Central Line). Cutoff is 70%.
