FIELD: medicine.
SUBSTANCE: invention relates to field of medicine, in particular to the field of marine medicine, and can be applied in practice of diving medicine for determination of degree of individual stability to decompression sickness (DS) in 20-30 year old men-divers. Estimation of clinical data, obtained in determination of the state of the organism's functions, is carried out. 30 minutes before and 30 minutes after submersion in pressure chamber under water carried out are: submersion to 30 metre depth, staying at said depth for 1 hour and 63 minute long decompression. Parameters, characterising the state of central nervous and cardiovascular system are determined, after which index of stability of DS (ISDS) is determined by formula: ISDS=1.243+0.0004×EI+0.074×EC+0.02×PP-0.072×CFLFF-0.004×SVMR-0.012×DAP, where: EI is Evans index, measured before descent, making it possible to estimate external heart work (conv.units); EC is endurance coefficient by Quaas, measured before descent, characterising detraining of myocardium (conv.units); PP is pulse pressure, measured after descent (Hg mm); CFLFF is critical frequency of light flash fusion, measured after descent (Hz); SVMR is simple visual-motor response, measured before descent (ms); ARP is diastolic arterial pressure, measured after descent Hg mm). If value is below 1.4, high degree of stability of DS is determined in diver, from 1.41 to 2 - medium degree of stability to DS and higher than 2.1 - low degree of stability to DS.
EFFECT: method makes it possible to increase accuracy of determining degree of individual stability to DS in 20-30 year old divers.
