Analysis of foetal haemodynamics using Doppler ultrasound is widely applicable in obstetrics in assessing foetal well-being. To evaluate the parameters of foetal circulation we examined 205 pregnant women to ascertain normal velocity ranges of the foetal internal carotid artery and the foetal renal artery. By establishing the ratio between the pulsatility indices of the foetal internal carotid artery, the foetal aorta and the renal artery of the foetus, standards of these were obtained. From this it seems to be possible to gain information on the extent and degree of the centralisation of foetal blood circulation.
