Joint criteria for evaluation of the functional status of the person

The paper deals with the task of formation a joint criteria for the functional state of the person evaluation based on heart rate variability parameters and synchronization degree between the cardiovascular and respiratory systems parameter. It is shown that proposed in previous studies method of forming a criterion of synchronization based on the Fechner's correlation coefficient has a significant correlation of the results with the results of psychological testing in the parameters “health”, “activity” and “mood”. Thresholds for given criterion of synchronization were established, which correlated with the stress level of the person. A new joint criteria based on stress index and criterion of synchronization, the corrected stress index, is offered. Conclusions about the effectiveness of the criteria developed are made.
