SYSTÈME DE DÉTECTION ÉLECTROENCÉPHALOGRAPHIQUE DUNE INADÉQUATION ENTRE LÉTAT DUN PATIENT PLACÉ SOUS ASSISTANCE VENTILATOIRE ET LE RÉGLAGE DE LA MACHINE UTILISÉE POUR CETTE ASSISTANCE, ET UTILISATION DE CETTE DÉTECTION POUR LADAPTATION DU RÉGLAGE
The invention relates to a system for electroencephalographic detection of an improper adjustment of a ventilator used on a mammal. The system includes an electroencephalograph, capable of measuring, as a function of time, an electroencephalographic signal representative of a breathing process and an input for receiving a respiratory initiation signal, different from the electroencephalographic signal, capable of indicating a respiratory initiation time. The detection system further includes means for specifying a beta frequency band comprised between 15 and 30 Hz and with a width comprising between 5 and 10 Hz means for processing the measured electroencephalographic signal, configured for processing the measured electroencephalographic signal as it is being acquired, in the sole specified beta frequency band and means for identifying, for each breathing cycle, an improper adjustment of the ventilator from the electroencephalographic signals processed in the sole beta frequency band.
