The determination of the circulating blood volume is still a stumbling block for obstetrician-gynecologists and anesthesiologists-resuscitators. Our view of the normal blood volume status during pregnancy is important in light of the assessment of the blood loss in the development of massive obstetric hemorrhage. The doctor needs to know what changes in the cardiovascular system are physiological and which are pathological in case of blood loss, with taking into account the functional changes in the heart that occur during pregnancy, parturition and in the earliest postpartum period. A deeper understanding of this problem will help the doctor avoid aggressive infusion therapy, which can lead to complications.blood volume statuspregnancythe cardiovascular systemphysiological changesassessment of blood lossволемический статусбеременностьсердечно-сосудистая системафизиологические измененияоценка кровопотери[Bedson R., Riccoboni A.
