Title (EN) METHOD AND ANAESTHETIC BREATHING APPARATUS
(FR) PROCÉDÉ ET RESPIRATEUR D'ANESTHÉSIE
Abstract:
(EN) A method for maintaining ventilation during an oxygen flush in an anaesthetic breathing apparatus (2) is disclosed. The breathing apparatus (2) comprises a breathing circuit (3), a fresh gas section (5), and a ventilator section (7). The fresh gas section (5) comprises an oxygen supply (12), and the ventilator section (7) comprises an expiratory pressure control valve (21). The method (100) comprises steps of: starting a continuous flow of oxygen from the oxygen supply (12) into the breathing circuit (3) interrupting an ongoing ventilation in order to activate the oxygen flush; maintaining the continuous flow of oxygen;, and cycling the expiratory pressure control valve (21) between an upper pressure level setting to provide an inspiratory phase of a breathing cycle and a lower pressure level setting to provide an expiratory phase of the breathing cycle.
(FR) L'invention concerne un procédé permettant de maintenir une ventilation pendant une purge d'oxygène dans un respirateur d'anesthésie (2). Le respirateur (2) comprend un circuit respiratoire (3), une section de gaz frais (5) et une section de ventilateur (7). La section de gaz frais (5) comprend une alimentation en oxygène (12), et la section de ventilateur (7) comprend une vanne de commande de pression expiratoire (21). Le procédé (100) comprend les étapes consistant : à démarrer un flux continu d'oxygène provenant de l'alimentation en oxygène (12) dans le circuit respiratoire (3) interrompant une ventilation en cours afin d'activer la purge d'oxygène; à maintenir le flux continu d'oxygène; et à mettre en cycle la vanne de commande de pression expiratoire (21) entre un réglage de niveau de pression supérieur pour fournir une phase inspiratoire d'un cycle respiratoire et un réglage de niveau de pression inférieur pour fournir une phase expiratoire du cycle respiratoire.
