VENTILATION APPARATUS FOR CARDIOPULMONARY RESUSCITATION WITH DISPLAY OF THE TREND IN CO2

摘要

The invention relates to a respiratory assistance apparatus for delivering a respiratory gas, such as air, to a patient during cardiopulmonary resuscitation (CPR), having a source (1) of respiratory gas, means (4) for measuring the CO₂ content, and signal-processing and control means (5). The signal-processing and control means (5) are configured to process the CO₂ content measurement signals corresponding to measurements performed by the CO₂ content measurement means (4) during a given period of time (dt), and to calculate at least one mean CO₂ content value (Vmean) from the maximum CO₂ content values (Vmax) obtained over the time window (Ft), and to transmit said at least one mean CO₂ content value (Vmean) to the graphical user interface (7) which displays it.
