Hemodynamics or haemodynamics are the dynamics of blood flow.The circulatory system is controlled by homeostatic mechanisms, just as hydraulic circuits are controlled by control systems.The haemodynamic response continuously monitors and adjusts to conditions in the body and its environment. Thus, haemodynamics explains the physical laws that govern the flow of blood in the … 2016-11-28 artery pulsatility index (UtA-PI) at 12, 22, 32 and 36weeks’ gestation in singleton pregnancies which develop pre-eclampsia (PE) and examine the performance of this biomarker in screening for PE. Methods UtA-PI was measured in 92712 singleton preg-nancies at 11–13weeks, in 67605 cases at 19–24weeks, pulsatility index: calculation of Doppler measurements of systolic and diastolic velocities in the uterine, umbilical, or fetal circulations.
