The volume of extracellular fluid under conditions of long-term space flights

The volume of extracellular fluid (the bromine space) was determined in 18 cosmonauts 30 days before the start of a space flight and on the first day after landing. The duration of space flights on the Mir orbital station was from 126 to 438 days. Moreover, the volume of extracellular fluid was dete...

Description
Summary:The volume of extracellular fluid (the bromine space) was determined in 18 cosmonauts 30 days before the start of a space flight and on the first day after landing. The duration of space flights on the Mir orbital station was from 126 to 438 days. Moreover, the volume of extracellular fluid was determined in seven cosmonauts directly during long-term space flights approximately two weeks before landing. After long-term space flights, the volume of extracellular fluid was decreased in all cosmonauts studied. The bromine space volume was significantly decreased compared to its initial preflight value. A decrease in the volume of extracellular fluid was caused not only by the reduction in the dense mass of the body but also by its dehydration. These processes developed independently of the duration of weightlessness but are mainly determined by the individual features of human beings.
