Abstract: 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.

Abstract: The specification describes an artificial resuscitation bag (5) having (i) a deformable bag (54) with a gas inlet (54A) and a gas outlet (54B), (ii) a pneumatic control valve (50) comprising an exhaust port (50c) adapted for controlling the flow of gas exiting to the atmosphere through said exhaust port (50c), and (iii) a monitoring module (60), operably connected to the pneumatic control valve (50) and having an absolute pressure sensor (60d) for measuring at least an absolute pressure (Pabs) in the inner compartment (50f) of the pneumatic control valve (50) and for transmitting at least an absolute pressure signal to a central processing unit (60c) and an ambient pressure sensor (60b) for measuring at least an atmospheric pressure (Patm) and for transmitting at least an atmospheric pressure signal to the central processing unit (60c).

Abstract: An apparatus for supplying gas, includes a ventilator having a motor, a rotor having vanes and a volute, a conduit for cooling the motor, and a soundproofing housing containing the ventilator and the conduit. The conduit has a shape similar to the wall of the motor and the volute, thus providing a flow path around the motor and the volute. The conduit also includes two housing portions, one of which includes a set of walls, forming a portion of the soundproofing housing and the conduit, and the other also includes a set of walls, forming the matching portion of the soundproofing housing and the conduit. The portions of the soundproofing housing and the conduit on the same portion of the housing are integral with one another, the two portions being suitable for being assembled together around the ventilator such as jointly to form the conduit and the soundproofing housing.

Abstract: An apparatus (1) includes a housing (2), an air feed duct (21) a volute (5), an impeller (4), and a motor (3) for driving the rotation of the impeller (4) so as to generate a centrifugal air flow in the volute (5). The housing (2) has a first part (18a) where wall is intended, after assembly, to extend around the motor (3), espousing the shape of this motor (3) in such a way as to lie at a substantially constant distance from this motor (3); and a second part (18b, 19) where wall is intended, after assembly, to extend around the volute (5), espousing the shape of this volute (5) so as to lie at a substantially constant distance from this volute (5). The housing (2) internally forms a salient axial lump (20) which, after assembly, sits close to the hub (10) of the impeller (4).
