Abstract

Ce système clos de réinhalation constitue un moyen sûr et efficace de ventilation par liquide qui, réduisant à leur minimum les pertes en fluide de ventilation en phase vapeur, permet d'abaisser la consommation dudit fluide et réduit au maximum le travail lié à un nouveau dosage. Il est possible d'employer un ventilateur ICU fonctionnant en modes normaux si l'utilisateur corrige la réduction de volume respiratoire (associé à la perte de la compliance pulmonaire) et intervient manuellement, si nécessaire, pour augmenter rapidement la concentration en oxygène. Ce circuit fermé permet de mesurer la consommation d'oxygène et sa déperdition.
