A ventilation bag for a manually operable ventilation device for the artificial ventilation of humans. The bag is made of an elastic, gastight material in the form of an elongated hollow body, with an essentially circular cross section perpendicular to its longitudinal axis with gripping surfaces for differentiated reduction of the volume of the hollow body along its length and having an air inlet opening at one end and an air outlet opening at the other end. To be able to administer different ventilation volumes with relatively greater accuracy and to reduce fatigue to a minimum, the gripping surfaces are arranged, essentially concentrically about the longitudinal axis and one behind the other in the direction of the longitudinal axis, at at least one end of the hollow body, the diameter of the hollow body decreasing toward that at least one end having the gripping surfaces.
