Title
(EN) SYSTEM AND METHOD FOR ADAPTIVE HIGH FREQUENCY FLOW INTERRUPTER CONTROL IN A PATIENT RESPIRATORY VENTILATOR
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE ADAPTATIVE DE COUPURE D'ÉCOULEMENT À HAUTE FRÉQUENCE POUR LE RESPIRATEUR D'UN PATIENT
Abstract
(EN)
A method and system for controlling fluid flow settings by receiving a precondition pressure wave function, representative of a precondition frequency, a precondition amplitude and a precondition pressure of the fluid flow in the system, establishing an operating pressure wave function, representative of an operating frequency, an operating amplitude and an operating pressure of the fluid flow desired in the system, determining cycle error between the precondition pressure wave function and the operating pressure wave function, converting the cycle error to flow adjustment, and updating an operating flow with the flow adjustment.
(FR)
L'invention concerne un procédé et un système de commande de réglages d'écoulement de fluide, le procédé comportant les étapes consistant à recevoir une fonction d'onde de pression de préconditionnement, représentative d'une fréquence de préconditionnement, d'une amplitude de préconditionnement et d'une pression de préconditionnement de l'écoulement de fluide dans le système, à établir une fonction d'onde de pression de fonctionnement, représentative d'une fréquence de fonctionnement, d'une amplitude de fonctionnement et d'une pression de fonctionnement de l'écoulement de fluide souhaité dans le système, à déterminer une erreur de cycle entre la fonction d'onde de pression de préconditionnement et la fonction d'onde de pression de fonctionnement, à convertir l'erreur de cycle en ajustement du débit et à mettre à jour un écoulement de fonctionnement par l'ajustement du débit.
