• Registration Number: NCT02792738
• Lead Sponsor: Association pour le Développement et l'Organisation de la Recherche en Pneumologie et sur le Sommeil

Brief Summary

The purpose of this protocol is to test the effect of hypnosis on laboratory dyspnea.

Detailed Description

This is a study of permissive suggestion in two laboratory models of dyspnea ("work/effort", "air hunger"). Breathing discomfort rating induced by laboratory models of dyspnea will be assessed before, during and after hypnosis.

Arm && Interventions

Group	Intervention	Description
hypnosis, visual distraction	hypnosis	This is a crossover study in which each subject will be exposed to a 5 min phase of hypnotic suggestion and visual distraction. For hypnotic suggestion, subject will be invited to experience a pleasant memory . Indirect and permissive suggestion will be used. For visual distraction, subject will be watching the movie "la marche des empereurs"

Primary Outcome Measures

Name	Time	Method
Subject rating of Breathing Discomfort (affective component of dyspnea)	continuous measurement for 5 minutes	Subjects will rate breathing discomfort using a visual analog scale at baseline (pre-intervention), during the intervention (hypnosis/ visual distraction) and after intervention (recovery) while subject will be submitted to the laboratory model of dyspnea for 5 minutes (three runs of laboratory dyspnea (baseline, intervention and recovery).
Subject rating of dyspnea intensity (sensory component of dyspnea)	continuous measurement for 5 minutes	Subjects will rate dyspnea intensity using a visual analog scale at baseline (pre-intervention), during the intervention (hypnosis/ visual distraction) and after intervention (recovery) while subject will be submitted to the laboratory model of dyspnea for 5 minutes (three runs of laboratory dyspnea (baseline, intervention and recovery).
