ABSTRACT

Blood is a specialized liquid tissue, composed of formed elements and a liquid part. The literature describes 55% for the liquid part (plasma) and 45% for the cellular fraction (erythrocytes, platelets and leukocytes); however, this general description is not sufficient to determine the exact amount of plasma and formed elements that an individual can have. The plasma is constituted in 90% of water and the rest corresponds to proteins, electrolytes, hormones, coagulation factors, immune complexes, gases, waste products, lipids mainly. The hematocrit is the percentage of the concentration of the blood cells, mainly the erythrocytes and is a determining factor to be able to perform the necessary calculations to perform therapeutic apheresis procedures. In general, all cell separators that currently exist require data on sex, weight, height, hematocrit and some other cellular accounts, in order to program the procedure we want to perform; that is why it is very important to have a blood count of the same day that the procedure is going to be performed, so that the separator can carry out the separation in an appropriate way, since it performs internal calculations to establish the separation interface according to the conditions of each patient and type of procedure.
