A deep vein thrombosis prevention garment includes a central panel formed with sequentially filled inner, intermediate and outer air chambers separated from each other with pressure resistive valves, a left side panel, and a right side panel formed with a number of attachment straps having an integral fastener. The inner air chamber receives air from a pump. When the air within the inner air chamber reaches a predetermined air pressure, the pressure resistive valve between the inner air chamber and the intermediate air chamber allows air to pass from the inner air chamber to an intermediate air chamber. When the air within the intermediate air chamber reaches a predetermined air pressure, the pressure resistive valve between the intermediate air chamber and the outer air chamber allows air to pass from the intermediate chamber to the outer air chamber. A membrane panel allows air to escape the sequentially filled air chambers.
