摘要： The invention relates to a medical ventilator (1) configured to provide respiratory assistance to a person in cardiac arrest, comprising a motorized blower (2), a gas circuit (3), and storage means (4) for storing ventilation modes (MV1, MV2) to be implemented during cardiac massage or in the absence of cardiac massage, in particular during an RSCA. Selection means (5; 5.1, 5.2) for selecting a ventilation mode (MV1, MV2) enable a user to select one of the stored ventilation modes, and control means (6) control the motorized blower (2) in response to the user's selection of one of said ventilation modes (MV1, MV2), so as to supply the gas at the desired low and high pressures.

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 AOImean on 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.

摘要： The invention relates to a medical respiratory assistance apparatus for delivering a respiratory gas such as air, which may or may not be enriched with oxygen, to a patient during cardiopulmonary resuscitation (CPR), having a source (1) of respiratory gas, for example a micro-blower, for delivering a respiratory gas to said patient during cardiopulmonary resuscitation (CPR), and means (4) for measuring the CO2 content, signal-processing and control means (5), and at least one graphical user interface (7). According to the invention, the signal-processing and control means (5) process the CO2 content measurement signals, to select the maximum CO2 content value (Vmax) during a given time period (dt), and to transmit this maximum value (Vmax) to the graphical user interface (7), which displays this maximum CO2 content value (Vmax).
