Abstract:
1. A device for detecting an improper adjustment of a ventilatory support machine used on a mammal, the device comprising: a measuring device configured to measure, as a function of time, a neurophysiological signal involved in the respiratory process of the mammal for at least two successive respiratory cycles, each respiratory cycle comprising a respiratory initiation time, the measuring device comprising an electroencephalograph; an input for receiving a respiratory initiation signal which is different from the neurophysiological signal; a processing unit configured to process the neurophysiological signal, the processing unit being configured to select, from the neurophysiological signal, one neurophysiological sub-signal for each respiratory initiation time, each neurophysiological sub-signal being formed by a portion of the neurophysiological signal extending over a period of time comprising the corresponding respiratory initiation time and starting before the corresponding respiratory initiation time, the processing unit being configured to process the neurophysiological sub-signals and to detect an occurrence of a premotor potential before the respiratory initiation time based on the processed neurophysiological sub-signals; and a detection unit configured to detect an improper adjustment of the ventilatory support machine based on the processed neurophysiological sub-signals, the improper adjustment being detected when the premotor potential occurring before the respiratory initiation time has been detected by the processing unit.
