![]() For example, when a blood clot blocks a blood vessel in the lung, the resulting pulmonary embolism can be fatal. Venous thromboembolism describes a blood clot breaking off and traveling through the circulatory system to block another vessel. Unfortunately, DVT often leads to more serious medical complications. Although symptoms-including swelling, pain, a feeling of warmth, or red skin-may accompany a deep vein blood clot, the condition can also develop without any noticeable signs. Another name for DVT is venous thrombosis. This body part is a particularly vulnerable area for bedridden patients, the NATF website explains: “As patients lay in bed, blood is more likely to pool in the calf, creating the right environment for a clot to form." What Is Deep Vein Thrombosis?ĭVT occurs when a blood clot forms in the deep veins, typically in the legs. An anti-embolism stocking is designed for those patients lying in bed, immobile, and it prevents blood from pooling in the calf. According to the NATF, "TED hose help reduce th risk by administering pressure on the lower part of the leg and feet-with the most compression occurring at the calf muscle. TED hose often provide uniform pressure throughout the sock, which means that the thickest part of the leg receives the most pressure. ![]() ![]() Because of this,TED hose are ideal for someone reclining in a bed. In contrast, most TED hose do not apply graduated pressure and, if they do, they provide more pressure to the calf. When you wear knee-high graduated compression stockings, the force of the compression gradient helps to stop blood and waste fluid from stagnating in the lower legs. The sock assists the veins as they move blood and lymphatic fluid from the lower extremities towards the heart.įor anyone standing or sitting for long periods, blood often pools in the lower limbs and feet. ![]() (For context, normal diastolic blood pressure measures 80 millimeters of mercury.) While this pressure pattern pushes blood from the ankle to the calf, the blood flows in the same direction inside the veins. This means that sock exerts 20 millimeters of mercury at the ankle and 15 millimeters of mercury at the calf. For example, a mild, graduated compression sock measures 15-20 mmHg. For that reason, the strength of a graduated compression sock is described using a pressure range, rather than a single measurement. Graduated compression garments provide pressure on a gradient, with the most pressure at the ankles and the least pressure at the calves. In fact, the North American Thrombosis Forum (NATF) recommends, "Patients may wear TED hose for up to three weeks, at which time they are mobile once again or have been prescribed a different treatment." What Is Graduated Compression? ( "Anti-Embolism" ) As a patient regains mobility after surgery, graduated compression socks typically become the more appropriate choice for preventing DVT. While compression socks and anti-embolism stockings both reduce the risk of blood clots and DVT, anti-embolism stockings are designed to be worn during times of decreased mobility such as a period immediately following sclerotherapy, endovenous ablation, phlebectomy, or any major surgery. ![]() Since bedridden patients stay in a reclining position, they usually do not need graduated compression, which works against gravity by exerting pressure up the leg. Typically, anti-embolism stockings offer uniform compression with a pressure level less than 20 mmHg. Whereas compression socks work well for people who are able to walk around, TED hose reduce the risk of DVT for non-ambulatory patients. Anti-embolism stockings-also called thrombo-embolic deterrent hose or TED hose- provide pressure, but do so with less force and often without an upward directional thrust.īoth compression socks and anti-embolism stockings help to prevent deep vein thrombosis (DVT) and pulmonary embolism. Compression socks, especially graduated compression socks, push blood and waste fluid from the feet towards the heart. The main difference between TED hosiery and other compression garments has to do with the way they apply pressure to the leg. ![]()
