A system and method prevents and diagnoses deep vein thrombosis in a body limb by providing a pressure sleeve having a plurality of individually fillable cells, the pressure sleeve being configurable to be placed around a body limb. A source fills each fillable cell individually, and a pressure sensor measures a pressure in a fillable cell. A controller establishes a fill sequence of each individually fillable cell and a fill time for each individually fillable cell. The controller causes a first individually fillable cell of the pressure sleeve to be filled to a predetermined pressure and causes the pressure of first individually fillable cell of the pressure sleeve to be measured while a second individually fillable cell of the pressure sleeve is filled. The controller determines a presence of deep vein thrombosis in a body limb having the pressure sleeve therearound based upon a measured pressure change in the first individually fillable cell of the pressure sleeve.
