Abstract

La présente invention concerne un procédé de guidage de respiration pour guider la respiration d'un sujet et ainsi amener le sujet à se détendre, le procédé de guidage de respiration permettant d'amener le sujet à se détendre dans une courte période de temps.　La présente invention concerne un procédé de génération d'une forme d'onde respiratoire cible ayant : une étape pour mesurer l'intervalle des battements de cœur d'un sujet et acquérir une première forme d'onde, il s'agit d'une forme d'onde fluctuante indiquant la fréquence cardiaque par unité de temps par rapport à un temps de mesure écoulé, la première forme d'onde ayant des valeurs maximales et minimales successives; une étape pour mesurer, pour une pluralité d'emplacements successivement, les différences de temps entre des positions auxquelles la première forme d'onde correspond à la valeur maximale, et pour forcer le sujet à respirer profondément jusqu'à ce que l'écart type relatif des différences de temps soit inférieur ou égal à 15 %; et une étape pour générer une forme d'onde respiratoire cible, il s'agit d'une forme d'onde fluctuante dans le temps pour une profondeur cible de respiration, la forme d'onde respiratoire cible ayant des valeurs maximales successives indiquant les moments où l'inhalation se transforme en expiration et des valeurs minimales indiquant les moments où l'expiration se transforme en inhalation. Dans l'étape de génération d'une forme d'onde respiratoire cible, lorsque les temps associés aux positions auxquelles la première forme d'onde correspond à la valeur maximale sont représentés par T1, T2,..., Ti,..., Tn et les temps associés aux positions auxquelles la forme d'onde respiratoire cible correspond à la valeur maximale sont représentés par t1, t2,..., ti,..., tn, n étant un nombre naturel supérieur ou égal à 3, la différence de temps (Ti-ti), entre le temps Ti à une position à laquelle la première forme d'onde correspond à la valeur maximale et le temps ti à une position à laquelle la forme d'onde respiratoire cible correspond à la valeur maximale est calculée pour la pluralité d'emplacements successivement, et une forme d'onde respiratoire cible ayant une fréquence à laquelle la différence de temps est la plus petite est générée.
