Normal cardiac output is 4-8 L/min
Normal cardiac index is 2.5-4 L/min/m2
Normal stroke volume is 60-100 ml/beat
Normal stroke volume index is 33-47 ml/beat/m2
A Low CO/CI may be observed with hypovolemia, hypoperfusion, shock, arrhythmia, and severe metabolic acidosis
A High CO/CI may be observed with hypoxia, the use of positive inotropes, early septic shock and anemia
A Low SV/SVI may be observed with impaired LV contractility, acidosis, hypoxemia, hypercapnia, increased afterload, decreased preload and tachycardia
A High SV/SVI may be observed with bradycardia, the use of positive inotropes, and decreases in afterload
