Abstract
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.
