The invention relates to a device for detecting the improper adjustment of a ventilatory support machine used on a mammal. The device (12) includes measuring means (40) for taking a measurement, as a function of time, of a neurophysiological signal involved in the respiratory process of the mammal for at least two successive breathing cycles, each breathing cycle comprising a respiratory initiation time; an input for receiving a respiratory initiation signal (to) which is different from the neurophysiological signal; means (42) for processing the neurophysiological signals, which are configured to process the neurophysiological signals for each respiratory initiation time over a period of time starting from the respiratory initiation time; and means (44) for detecting an improper adjustment of the ventilator using the processed signals.
Le dispositif (12) comporte des moyens (40) de mesure, en fonction du temps, d'un signal neurophysiologique mis en AEuvre dans le processus respiratoire du mammifère pour au moins deux cycles respiratoires successifs, chaque cycle respiratoire comportant un instant de déclenchement respiratoire; une entrée pour la réception d'un signal de déclenchement respiratoire (to) différent du signal neurophysiologique; des moyens (42) de traitement des signaux neurophysiologiques, configurés pour traiter les signaux neurophysiologiques, pour chaque instant de déclenchement respiratoire, sur un intervalle de temps comprenant l'instant de déclenchement respiratoire et s'étendant en avance de l'instant de déclenchement respiratoire; et des moyens (44) de mise en évidence d'un réglage inapproprié du ventil-teur à partir desdits signaux traités.
