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).
