Abstract
Cette invention concerne un dispositif et un procédé de ventilation d'un patient permettant de réduire le flux régulé par rapport à des ventilateurs oscillatoires. Le dispositif comprend un circuit d'écoulement gazeux comportant un conduit oscillant, un conduit d'alimentation et un conduit d'expiration ou un conduit de retour. Une canalisation d'amenée du gaz et une soupape de sortie sont en communication pneumatique avec le circuit d'écoulement gazeux. Le circuit comporte un ou plusieurs épurateurs de CO¿2? et un ou plusieurs clapets anti-retour. Est également décrite une méthode de ventilation à l'aide d'un tel dispositif.
