Evaluation of Respiratory Function During Self-induced Cognitive Trance

Study Overview
=================
Brief Summary
-----------------
The goal of this Prospective, monocentric, non-randomized, open-label study aimed at evaluating the variation of FEV1 during a state of self-induced cognitive trance participant population: Person with expertise in the practice of TCAI can be inclued. (at least 6 months, in order to be able to control the depth of the trance and to have a motor control allowing the realization of a spirometry) The main question: Study the significant variation of FEV1 before, during, or after the state of self-induced cognitive trance

Detailed Description
-----------------
Primary objective : Study the significant variation of FEV1 before, during, or after the state of self-induced cognitive trance judgment criteria: Significant variations in: PEF PEF25 PEF50 PEF75 FVC Inspiratory capacity, SpO2 Respiratory rate before, during, or after the self-induced cognitive trance state Evolution of the feeling of self-efficacy, assessed by questionnaire
