The invention refers to a method and an apparatus for changing the concentration of a target gas at the blood compartment of a patient's lung from an actual target gas concentration to a desired target gas concentration during artificial ventilation with an inspiratory gas composition by a respirator being controlled via a set of ventilation parameters. In order to decrease the negative effects of general anaesthesia during artificial ventilation even further, the method according to the invention comprises the following steps: a) ventilating the lung in a first ventilation stage, and b) ventilating the lung in a second ventilation stage in which alveolar recruitment is promoted.
L'invention concerne un procédé et un appareil permettant de modifier la concentration en gaz cible au niveau du compartiment du sang d'un poumon d'un patient d'une concentration en gaz cible actuelle à une concentration en gaz cible souhaitée, pendant une ventilation artificielle, au moyen d'une composition de gaz inspiratoire, grâce à un respirateur commandé par le biais d'un ensemble de paramètres de ventilation. Afin de diminuer les effets négatifs de l'anesthésie générale pendant la ventilation artificielle de manière plus importante, le procédé selon l'invention comprend les étapes suivantes consistant: a) à ventiler le poumon au cours d'une première étape de ventilation et b) à ventiler le poumon au cours d'une seconde étape de ventilation pendant laquelle le recrutement alvéolaire est favorisé.
