Pediatric low cardiac output syndrome

Low cardiac output syndrome is the most serious physiological abnormality in cardiac surgery, and it is one of the main causes of patient death after surgery. The cardiac output of a normal person is calculated based on the area per square meter, that is, the heart index is 3 to 4 L / (min · m2). If the heart index decreases below 3L / (min · m2), there is a phenomenon of peripheral blood vessel contraction and insufficient tissue perfusion, which is called low cardiac output syndrome.
