METHOD FOR MEASURING INDIVIDUAL PERSISTENCE TO COMPRESSED-AIR DISEASE IN FEMALES AGED 30-40 Russian patent published in 2014 - IPC A61B5/205 

FIELD: medicine.

SUBSTANCE: method involves immersing in a decompression chamber at a depth of 30 metres, staying at this depth for 1 hour and decompressing for 63 minutes. The following values are determined 30 minutes before the immersion: systolic blood pressure (SBPbi), heart rate (HR) and moving object response (MOR). The following values are determined 30 minutes after the immersion in the decompression chamber: systolic blood pressure (SBPai) and critical flicker fusion frequency (CFFF). That is followed by determining an index of persistence to decompression disease (DD) in the females aged 30-40 (IPDDF_30-40) by formula: IPDDF_30-40=0.442+0.032×SBPbi+0.017×SBPai-0.032×HR-0.009×MOR-0.017×CFFF-0.048×age, wherein SBPbi is the systolic blood pressure measured before the immersion, mm Hg; SBPai is the systolic blood pressure measured after the immersion, mm Hg; HR is the heart rate measured before the immersion, beats per minute; MOR is the moving object response measured before the immersion, ms; CFFF is the critical flicker fusion frequency measured after the immersion, Hz; age is the age, completed years. If IPDDF_30-40 is 1.1 included, the high persistence to DD is stated in the female; the value falling within the range of 1.1 to 2.19 included shows the moderate persistence to DD is stated; and if the value of more than 2.19, the low persistence to DD is shown.

EFFECT: method provides the differentiated assessment of the persistence to DD in the females of certain age with using no additional equipment.
