d) To improve circulation in the legs.

Answer 1

A pneumatic compression device is used to improve leg circulation and prevent deep vein thrombosis by reducing swelling and helping return blood to the heart.

Step-by-step explanation:

The purpose of a pneumatic compression device is to improve circulation in the legs and prevent deep vein thrombosis (DVT). These devices are commonly used in healthcare to reduce swelling (or edema) due to fluid accumulation and to aid in the return of blood to the heart, especially after surgery or when a patient is immobile. By applying varying pressures at regular intervals, they mimic the natural blood flow and help to prevent blood from pooling in the legs, a condition that can lead to DVT, a potentially dangerous blood clot formation.

When a person stands for a long time, blood can accumulate in the legs, causing swelling and increasing the risk of fainting. Elastic bandages and tight stockings are recommended in some situations, such as during long flights, to apply pressure and assist the veins in sending blood back to the heart. The use of a pneumatic compression device follows a similar principle but is automated to provide consistent and regulated compression to the limbs.
