Abstract
(EN) There is a ventilator for mechanical ventilation during a breathing cycle including an 10 inhalation cycle and an exhalation cycle. The ventilator is configurable to be in fluid communication with a supply of a first fluid. The ventilator includes an inhalation pathway and an exhalation pathway. A first fluid injector is in fluid communication with the supply of the first fluid for injecting the first fluid. The inhalation pathway receives the first fluid injected by the first fluid injector. A controller is operatively 15 connected with the first fluid injector and programmed to selectively actuate the first fluid injector to inject the first fluid, which is received within the inhalation pathway such that an inhalation pressure in the inhalation pathway is within a predetermined range during the inhalation cycle.
(FR) L'invention concerne un ventilateur permettant une ventilation mécanique pendant un cycle respiratoire comprenant un cycle d'inspiration et un cycle d'expiration. Le ventilateur peut être configuré pour être en communication fluidique avec une alimentation d'un premier fluide. Le ventilateur comprend une voie d'inspiration et une voie d'expiration. Un premier injecteur de fluide est en communication fluidique avec l'alimentation du premier fluide pour injecter le premier fluide. La voie d'inspiration reçoit le premier fluide injecté par le premier injecteur de fluide. Un dispositif de commande est relié fonctionnellement au premier injecteur de fluide et programmé pour actionner sélectivement le premier injecteur de fluide pour injecter le premier fluide, qui est reçu à l'intérieur de la voie d'inspiration de telle sorte qu'une pression d'inspiration dans la voie d'inspiration se situe dans une plage prédéterminée pendant le cycle d'inspiration.
