A review is presented of the latest data on the relationship between the blood flow velocity waveform in the lower thoracic part of the fetal descending aorta, internal carotid and umbilical artery and fetal behavioral states, in particular state 1F and 2F [1], in the normal-growing and growth-retarded fetus at term. Fetal neurological development, expressed by the emergence of fetal behavior and eventually resulting in well-distinguishable fetal behavioral states, is clearly associated with specific hemodynamic adaptations. The asymmetrically growth-retarded human fetus is capable of modifying this relationship. In the analysis of blood flow velocity waveforms for clinical purposes, fetal behavioral states and fetal heart rate have to be taken into account for a proper interpretation of recorded data.
本文综述了足月正常生长和生长受限胎儿的胎儿降主动脉下段、颈内动脉和脐动脉血流速度波形与胎儿行为状态（特别是1F和2F状态[1]）之间关系的最新数据。胎儿神经发育表现为胎儿行为的出现，并最终导致可明确区分的胎儿行为状态，显然与特定的血流动力学适应有关。不对称生长受限的人类胎儿能够改变这种关系。在出于临床目的分析血流速度波形时，必须考虑胎儿行为状态和胎儿心率，以便正确解读记录的数据。
