What are the expected results when using sequential or pneumatic compression devices?

Using sequential or pneumatic compression devices is primarily aimed at reducing swelling and improving circulation in patients, particularly those who may be immobile or have poor blood flow. These devices work by applying controlled pressure to the limbs, which helps promote venous return and can prevent blood clots.

The mechanism operates by inflating and deflating, mimicking the natural muscle activity that occurs during physical movement. This helps push blood back toward the heart, effectively alleviating edema and enhancing overall circulation.

The other options, while they may be influenced by general mobility and circulation, do not directly relate to the primary function of sequential or pneumatic compression devices. For instance, stimulating walking and moving refers to physical activity that is unrelated to the device's function. Preventing skin breakdown is more related to pressure relief and skin integrity. Enhancing digestion, although it can be influenced by overall health and movement, does not directly correlate with the primary action of these compression devices.
