The patient should wear SCDs for 21 hours a day. In order to be effective in preventing both DVT and VTE a SCDs should be worn for 90% of a 24 hour period. How Long Can a Sequential Compression Device be Worn? Synthetic tPA is a medication that is used to break up clots in a heart attack patient. This protein is found on the cells that line the blood vessels. tissue plasminogen activator is a protein that is involved in the breakdown of blood clots. These devices have been shown to increase the amount of tissue plasminogen activator -tPA. The intermittent compression of the sleeves, jackets, or boots ensures the movement of venous blood. When the sleeves deflate the veins will replenish with blood again. The most distal chambers will inflate first, and then subsequent packets will follow the same manner to help squeeze the blood from underlying deep veins. Typically the sleeve, jacket, or boot has multiple chambers that work together to inflate in a series to squeeze the limb in a “milking action”. Pressure lines are connected between the controller pump and the sleeves and when turned on, the sleeve, jacket, or boot inflates with air. Inflatable sleeves, jackets, or boots enclose the limb that requires treatment. Intermittent pneumatic compression is an established method used to prevent deep vein thrombosis (DVT) or pulmonary embolism (PE). SCDs work to not only reflow blood but to prevent deep vein thrombosis or a pulmonary embolism. After the pressure is applied, the blood is able to flow freely through the extremity. Air is pumped in the chamber and put on the swollen body part. The device is put on the extremity that has severe swelling. A sequential compression device works by applying pressure to recirculate blood and allow blood to flow to all vital organs and extremities. Deep vein thrombosis is when a blood clot is formed in a vein. A pulmonary embolism is a blood clot that can get lodged in the lungs, or into the heart. Limited blood flow may cause a pulmonary embolism. When the blood cannot be distributed, the patient’s safety is at risk. By limiting blood flow, the nutrients, oxygen, and water in the blood cannot be distributed to the necessary organs. If people are bedridden, the blood is unable to flow to each vein in the extremities. Sometimes, people have circulatory issues from some diseases, or because they have limited mobility. The main goal of sequential compression devices is to recirculate the blood in a person’s body. The SCD medical abbreviation stands for sequential compression device. Continue reading to learn more about the Sequential Compression Device ( SCD). These devices can be used in hospitals and are approved for at-home use. Sequential compression devices are medical equipment devices that help to improve circulatory function in people who have poor circulatory flow.
