Abstract

La mise en oeuvre de systèmes créant une pression positive en fin d'expiration (PEEP) se traduit par une diminution du débit cardiaque et du flux sanguin local, le coeur étant entouré d'une pression plus élevée que d'habitude (pression intrathoracique accrue). La présente invention permet de diminuer sélectivement la pression intrathoracique durant une faible partie du cycle cardiaque lorsqu'elle est le plus dommageable. Ladite invention permet de réduire la pression thoracique en fournissant une source de basse pression à la soupape PEEP (14). Sont décrits un moyen de détection (16) permettant de détecter les battements cardiaques séquentiels d'un patient, ainsi qu'un moyen de calcul (18), lequel est connecté au moyen de détection (16), pour calculer une période entre les battements cardiaques séquentiels. En outre, un organe à soupape (24) est connecté électriquement au moyen de calcul (18) et pneumatiquement au moyen de ventilation (12) afin de commander ce dernier, l'organe à soupape (24) étant positionné de manière à arrêter l'alimentation en pression positive en fonction de la période calculée.
