(EN) METHOD AND APPARATUS FOR CONTINUOUS MANAGEMENT OF AIRWAY PRESSURE FOR DETECTION AND/OR PREDICTION OF RESPIRATORY FAILURE

Abstract
(EN)
Various embodiments are described herein for a controller for controlling the operation of a breathing assistance device that provides breathing assistance to a user. The controller comprises a processor that generates a respiratory index value that is determined during a current monitoring time period to detect a respiratory failure, or predict the respiratory failure when at least one PSG signal is measured. The respiratory index value is compared to a threshold to determine if the control signal needs to be updated to reduce or eliminate respiratory failure that the user is currently experiencing or to prevent a predicted respiratory failure from occurring.

Selon divers modes de réalisation, la présente invention concerne un dispositif de commande destiné à commander le fonctionnement d'un dispositif d'assistance respiratoire qui fournit une assistance respiratoire à un utilisateur. Le dispositif de commande comprend un processeur qui génère une valeur d'indice respiratoire qui est déterminée pendant une période de temps de surveillance actuelle pour détecter une insuffisance respiratoire, ou prédire l'insuffisance respiratoire lorsqu'au moins un signal PSG est mesuré. La valeur d'indice respiratoire est comparée à un seuil pour déterminer si le signal de commande doit être mis à jour pour réduire ou éliminer une insuffisance respiratoire que l'utilisateur subit actuellement ou pour empêcher la survenance d'une insuffisance respiratoire qui a été prédite.
