How does Aqualung work? The aqualung introduced a regulator system that allowed divers to inhale and exhale through the same mouthpiece, significantly improving oxygen efficiency and mobility. Cousteau and gagnan’s design utilized high-pressure metal tanks filled with compressed air, enabling divers to reach depths of up to 68. Jacques cousteau and emile gagnan together invented
