Abstract :
The review is devoted to the prevention of neonatal asphyxia by assessing the reserves of adaptation of the fetus to intrauterine hypoxia in the second half of pregnancy and then choosing a safe type of delivery. The history of development of a new functional test that provides a non-invasive assessment of fetal adaptation reserves to intrauterine hypoxia using sonography is shown. It is proposed to use ultrasound to determine the duration from the beginning of apnea in a pregnant woman to the appearance of a distress signal, the fetus inside the uterus when its reserves of adaptation to hypoxia are exhausted. If a distress signal appears earlier than 10 seconds from the start of breath retention of pregnant woman is recommended to refuse of physiology birth and is offered delivery by Cesarean section.
