Abstract

La présente invention concerne un procédé et un appareil permettant de fournir de l'air régulé avec précision à un patient nécessitant une assistance respiratoire. On utilise un amplificateur de débit d'air de type venturi; une commande numérique incrémentielle d'un vide d'air fournissant de l'air comprimé à l'amplificateur. L'air comprimé induit et entraîne de l'air ambiant en quantités importantes, ce qui fournit au patient un flux fortement amplifié d'air non turbulent. Les flux combinés sont soumis à des mesures rapides et répétitives de pression et de conditions d'écoulement, ces mesures servant de données de rétroaction permettant de gérer au plus près le fonctionnement du système. Dans divers modes de réalisation, le procédé et le système de l'invention fournissent une assistance à la respiration spontanée du patient, qui peut être contournée par des moyens de synchronisation, si le patient n'arrive pas à respirer naturellement pendant trop longtemps. Le système assure étalement une mesure du volume respiratoire du patient, garantissant qu'un volume suffisant d'air est inhalé et exhalé par le patient pour éliminer l'excédant de CO2 des poumons du patient. L'amplification passive de l'air offre un fonctionnement particulièrement silencieux, ce qui permet un meilleur sommeil du patient. Ce système qui n'est pas seulement efficace, est également exceptionnellement économique à installer et mettre en oeuvre.
