Fetal Cardiac Output Calculations

Inspired by the 2001 manuscript from Mielke and Benda, Cardiac output and central distribution of blood flow in the human fetus.

Cardiac output z-scores according to the 2018 data from Rocha et al., Z-Score Reference Ranges for Fetal Heart Functional Measurements in a Large Brazilian Pregnant Women Sample.
