Pneumatic compression boot is designed to apply intermittent pneumatic compression of the lower limbs , in order to help increase venous blood flow in patients at risk, seeking to prevent deep vein thrombosis ( DVT) by compressing limbs.
The boots contain three cameras for generating a gradient sequential compression . They have a Velcro closure with adjustable , making it personalized for each patient.
Generally, they are used in conjunction with stockings elastocompression collaborating in the treatment for the following types of patients:
· Patients immobilized pre, intra and post surgical ;
· Elderly patients requiring bed;
· Before and after birth;
· Patients on therapy units and / or prolonged hospitalization.

Why use pneumatic compression boots ?
In a patient immobilized for a long period may be prescribed pneumatic compression boots to prevent deep vein thrombosis ( DVT). Attached to a pump and applied to one or both legs, boots are fabric wraps containing internal cavities that swell intermittently to compress the legs and push blood forward. There are different models for the calf, thigh or both.
How the leg compression prevents DVT?
Intermittent compression force blood from the blood vessels of smaller caliber to deeper and into the femoral veins . Facilitation decreases venous blood flow stagnation and congestion dispersed coagulation factors and facilitates locally activated fibrinolysis. In addition, compression decreases the relaxation of the vessels , which reduces the risk of injury coat endotelial.Debe note that the system of intermittent compression of the lower limbs by pneumatic boots is a complementary method to existing prevention DVT and not replaced.
Who is at risk ?
People who stay long periods in bed or immobilized after surgery or fractures. Surgical procedures trigger multiple biological mechanisms that predispose to venous thrombosis.
Although anyone can get TVP , there are some factors that increase your risk of presenting it . Having more than one risk factor increases the risk even more .
Pregnancies are also a major risk factor . The changes that occur in the blood during pregnancy facilitate the formation of clots. The risk of DVT is almost 10 times higher during pregnancy. This risk remains high for 4 to 6 weeks after giving birth.
Women who take birth control pills are at greater risk of DVT than those not using them. This risk is increased in women using hormone therapy after menopause . Smoking and age also increases the risk .
Risk factors for DVT
Among the events or situations that may increase the risk of DVT include the following: surgery, trauma , extensive periods without movements ( stay in bed, sitting in extensive travel ) , Cancer and cancer treatment , history of DVT advanced age, pregnancy and the period of 4 to 6 weeks postpartum , contraceptive drugs that contain estrogen or hormone therapy for symptoms of menopause, certain diseases such as heart failure , inflammatory bowel disease and some kidney disorders . Obesity , smoking , varicose veins, intravenous catheters, thrombophilia , etc.
