METHOD FOR PREDICTION OF RESCUE WORKERS' ADAPTATION LEVEL TO PERSONAL PROTECTIVE EQUIPMENT Russian patent published in 2014 - IPC A61B5/452 A61B5/402 A61B5/02 A61B5/476 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, labour safety, vocational selection of rescue workers. The invention can be used for vocational selection in the sectors of industry using personal protective equipment, as well as for the workers labour safety in the sectors of industry with harmful working conditions. The method involves vocational selection and duty control on the basis of electroencephalogram (EEG) values and cardiological findings. The examination is performed prior to and when using the personal protective equipment. The cardiological examination involves assessing the heart rate variability with using the amplitude-frequency spectrum Fourier analysis VLF at a vibration frequency within the range of 0.0033-0.04 Hz, LF - at a frequency of 0.05-0.15 Hz and HF - at a frequency of 0.16-0.80 Hz, and is five-staged: initial resting state, mental work load, recovery of mental work load, hyperventilation load, recovery of hyperventilation load. At the beginning, the heart rate variations and EEG are examined prior to using the personal protective equipment. If any of the five stages of the heart rate variation examination shows the pulse more than 90 beats per minute, as well as changes from the normal values of: approximating entropy - less than 180, LF - less than 6 point, an alpha wave amplitude - to 12 vibrations per second and the presence of the paroxysmal activity by EEG, the prevailing sympathetic nervous system is stated, or if any stage of the heart rate variation examination shows the pulse less than 60 beats per minute, as well as changes from the normal values of: blood pressure - more than 140/90 mmHg, VLF - more than 130 points, HF - more than 16 points, an alpha wave amplitude - less than 25 mcV, the prevailing parasympathetic nervous system is stated; a low level of adaptation to the personal protective equipment is predicted, and a rescue work is not recommended during the vocational selection; the examination is terminated. If the heart rate variation and EEG prior to using the personal protective equipment fall within the normal values, the heart rate variation when using the personal protective equipment is started with the patient examined when using the personal protective equipment and performing a cycle ergometer test, and recording the hyperadaptotic changes of the assessed values: VLF - more than 130 points in relation to the normal value when using the personal protective equipment and LF and HF vibrations; an incomplete or unfinished adaptation to the personal protective equipment, and the rescue worker is suspended from work for several hours; if VLF is more than 130 points recorded 10-15 min after activating the personal protective equipment, a good adaptation level to the personal protective equipment is predicted.

EFFECT: method enables assessing the vegetative nervous function and predicting the rescue workers' adaptation level to the personal protective equipment.
