Summary

This study is aimed to develop analysis methods and measurements tools for physiological variables : respiration, circulation and their mutual interactions and with the functions involved in the daily life in healthy volunteers (drinking, eating, sleeping, coughing...). The devices that are used are non invasive. The development of these tools needs to be validated on physiological signals obtained in healthy volunteers.

Detailed description

The analysis and interpretation of a record consist, for example, to measure the amplitude of the respiratory modulation of the cardiac period, a witness of the level of the subject's sympathetic activity. To do this, a mathematical model of this oscillation is adjusted on the experimental data, and its characteristics (amplitude, phase, non-linearity...) are considered indexes of the interaction to be compared with the same characteristics in other conditions. The transition to clinical applications requires validation of the developed tools on physiological signals recorded on healthy volunteers in a non-clinical environment, avoiding extra psychological stress in the Protocol followed. Whether it is for the development of tools or their validation, it is essential that the sensors used are non-invasive. Recorded situations are those of everyday life, such as working (only sedentary work are envisaged), eat, talk, rest and move from one place of life to another one.
