Abstract

L'invention concerne un nouveau procédé de ventilation et d'échange de chaleur appelé ventilation par liquide en mode mixte (MMLV : mixed mode liquid ventilation). Ce procédé comprend l'utilisation d'un cathéter endothrachéal (fig. 1a et 6b) permettant d'ajouter et de retirer du liquide des poumons de manière continue et/ou cyclique, et d'administrer un gaz à un débit indépendant de l'administration de liquide. Ce procédé produit un mélange de gaz et de liquide à petite échelle dans les voies respiratoires, permettant un échange efficace de gaz et de chaleur. L'invention concerne également des applications médicales de ce procédé, parmi lesquelles l'induction et l'inversion de l'hyperthermie et de l'hypothermie.
