  • the defibrillator 100 may determine whether the current ECG intensity of the patient is less than the second threshold. If the ECG intensity is smaller than the second threshold value, the process may proceed to step S901. On the other hand, if the ECG intensity is greater than the second threshold, the patient is conscious and ends the operation.
  • each step of FIG. 9 may be performed in the reverse order, or may be performed simultaneously.
  • FIG. 7 illustrates a case in which step S909 is performed after step S907 is performed, but this is merely an example for description, and steps S907 and S909 may be performed regardless of the order or at the same time.

Abstract

Un mode de réalisation de la présente invention concerne un procédé de fonctionnement d'un défibrillateur qui comprend les étapes consistant à : mesurer au moins une valeur parmi les valeurs d'éclairement externe, de vibration et de son ; afficher un écran qui est réduit ou plus sombre qu'un écran en mode normal lorsqu'au moins l'une parmi les valeurs d'éclairement externe, de vibration et de son mesurées est inférieure à une première valeur seuil ; et afficher un écran qui est agrandi ou plus lumineux que l'écran en mode normal lorsqu'au moins l'une parmi les valeurs d'éclairement externe, de vibration et de son mesurées est supérieure à une seconde valeur seuil, la seconde valeur seuil pouvant être supérieure à la première valeur seuil.
