MONITORING OR VENTILATION APPARATUS FOR CARDIOPULMONARY RESUSCITATION WITH DETERMINATION OF AN AIRWAY OPENING INDEX

摘要

The invention relates to a monitoring and/or respiratory assistance apparatus that can be used during a cardiopulmonary resuscitation (CPR) with successive chest compressions of duration (dt) performed on the patient and with relaxations, said apparatus comprising a CO₂ content measurement sensor (10) a graphical user interface (14), and signal-processing system (11) configured to process the CO₂ content measurement signals in such a way as to determine at least one maximum CO₂ content value (Vmax) and at least one minimum CO₂ content value (Vmin), during at least one duration (dt) of at least one chest contraction, and then to calculate at least one airway opening index AOI or mean index AOI_meanon the basis of the CO₂ content values. Said one or more indices are displayed on the GUI in the form of numerical values or graphical representations, especially curves or pictograms.
