Which device is used to prevent thrombus formation in immobile patients?

Explanation:
Immobility slows venous blood flow in the legs, increasing the chance of clot formation (venous stasis). Sequential compression devices provide intermittent external pressure to the calves, mimicking the normal muscle-pump action. This boosts venous return, reduces pooling, and lowers the risk of thrombus development in patients who cannot move. The other devices don’t address clot prevention in this way: ambulatory aids help with movement but don’t mechanically reduce venous stasis; a pacemaker treats heart rhythm; an oxygen concentrator delivers oxygen.
