Flotation device for rescue apparatus includes a support portion onto which an injured person is placed, and a buoyant structure connected to the support portion to provide buoyancy for the support portion. The buoyant structure includes one or more fluid containers each attached to the support portion by, for example, straps. At least one pressure regulating mechanism is integrated into or onto a surface of each container and functions to vary pressure of fluid in the hollow space of the container, and may include inflation mechanisms that enable controlled inflow of fluid into the hollow space of the containers, and deflation or pressure release mechanisms that enable controlled outflow of fluid from the hollow space of the containers. |
