A technique, Mixed-mode Liquid Ventilation (MMLV), for ventilation, and heat exchange is disclosed. The technique uses an endotracheal catheter (Figs. 1a and 6b) to add, to remove liquid from the lungs of user continuously/cyclically, and delivers gas at a rate independent of the delivery of liquid. This technique produces small scale mixing of gas, liquid in the user's airways, allowing efficient gas, and heat exchange. Medical uses for the technique are disclosed, that include induction, reversal of hyperthermia, and hypothermia.
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.
