Abstract

When comparing cardiac outputs in children of different sizes, or deciding on the normality of these outputs, we often convert the absolute output to the output per m body surface area-the cardiac index. For small infants, this leads to potentially large errors. The best way to evaluate these outputs is to determine their z values.
