A deep vein thrombosis prevention garment includes three (3) chambered polymer having an integral welded filling tube forming three (3) sequentially filled air chambers. The aft chambers receive air from an integrated fill tube attached to pump. When the air within the first air chamber reaches a predetermined air pressure, air begins to pass into a second air chamber at a higher rate, and similarly, when the air within the second air chamber reaches a predetermined air pressure, air passes into the third air chamber at another higher rate to reach the predetermined air pressure. The different internal diameters of the integrated fill tube outlets for each air chamber provide different air flow rates, resulting in staged inflation of air chambers. A membrane panel allows air to escape the sequentially filled air chambers.
