Lifesaving devices for providing flotation support to their users, and comprising a pressurized gas container, a flotation balloon and a valve for releasing the pressurized gas into the flotation balloon. The method of designing the devices comprises selecting a gas charge for the pressurized gas container, having a high molecular weight, such that, for a specific lifesaving device, the diffusion of the gas charge through the walls of the pressurized gas container are reduced, as compared with a gas charge having a lower molecular weight. The device therefore has a longer shelf life before the need to recharge the gas fill. The use of such a high molecular weight gas also reduces the diffusion of the gas charge through the walls of the flotation balloon, such that the device fulfils its purpose of supporting the user in water for a longer period of time.
