Abstract: The invention concerns a manual artificial respiration bag (1) for ventilating a patient in need thereof, comprising a deformable bag (10) with a gas inlet (11), a gas outlet (12) and an inner volume (13) for a respiratory gas; an upstream conduct element (20) fluidly connected to the gas inlet (11) of the deformable bag (10), and comprising a gas entry port (21); and a downstream conduct element (30) fluidly connected to the gas outlet (12) of the deformable bag (10), comprising an exhaust valve (35) comprising an exhaust port (36). A venturi device (50) comprising a main body (110) comprising a venturi nozzle (120); at least one oxygen inlet (131) for providing oxygen; at least one air inlet (132) for providing air; a mixing chamber (133) for mixing therein oxygen and air and obtaining an air/oxygen mixture; and gas selection means (110, 130) for selecting oxygen or an air/oxygen mixture as a desired gas to be provided to the venturi nozzle (120). The venturi nozzle (120) is in fluid communication with the upstream conduct element (20), via the gas entry port (21), for providing the desired gas to the upstream conduct element (20), such as oxygen or an air/oxygen mixture.
