    The experimental scheme for detection of foreign particles Analysis stages:  Determination of the chemical composition of foreign particles by Raman spectrums;  Determination of the area of each foreign particle S 1 , S 2 . . . S i ;  Calculation of particle concentration: n = N/(S•d) [unit./ml]; Calculation of the volume fraction of particles: ω = (100 (S 1 +S 2 +...S i ))/S [%]; N is the number of found foreign particles; s is the area in [cm 2 ] occupied by the test solution; d -layer thickness in [cm] occupied by the test solution. Optical microscopy and Raman spectroscopy in a 20% SMOFlipid solution revealed homogeneous microparticles with sizes from 1 µm to 50 µm (average size ~ 10µm, an average concentration of 10,000 particles / ml, and a volume fraction of 6.4 • 10 −3 . Filters of standard medical droppers with a pore diameter of 150 microns do not retain the above described microparticles. The circulation of microparticles through the bloodstream for 60 minutes was experimentally established when the centrifuged plasma of women aged 19 to 42 was added (10 to 1 by volume) to each of the AB0 / rhesus combinations. The average size of microparticles at 36.6°C did not change within 60 minutes, which is due to the specifics of the enzymatic activity of plasma albumin, liver and kidney enzymes and the properties of cell receptors. The Doppler method was used to calculate the transit time of the injected solution through the subclavian vein of fullterm newborns -0.07 s, which is incomparable with the period of lipolysis activation 60 minutes. When microparticles enter the pulmonary and cerebral bloodstream, they cause microembolism, which leads to a pathological decrease in ventilation-perfusion relations.
