![]() ![]() The relative efficacy of the two devices in deep vein thrombosis prevention should be tested in future studies. This was enhanced further by the sensing of refill time, which resulted in more compression cycles over time. Data Element Scope: This value set may use a model element related to Device. Sequential compression showed hemodynamic superiority compared to a rapid inflation device. Clinical Focus: The purpose of this value set is to represent concepts of devices using intermittent pneumatic compression devices for venous thromboembolism (VTE) prophylaxis. Although peak velocity enhancement was higher with the rapid inflation device, flow augmentation (a product of average blood flow velocity) was comparable (669+/-367 vs 771+/-574 cm/s P=0.223) with the sequential compression device, mainly because the rapid inflation device failed to maintain flow enhancement beyond the initial flow surge. This increases blood flow through the veins of your legs and helps prevent blood clots. The devices use cuffs around the legs that fill with air and squeeze your legs. Similarly, the total volume of blood expelled per hour with the sequential compression device was 100% higher than the rapid inflation device (9685+/-5426 vs 4853+/-3658 mL P<0.001). What are intermittent pneumatic compression devices Intermittent pneumatic compression (IPC) devices are used to help prevent blood clots in the deep veins of the legs. The sequential compression device, by augmenting flow throughout a significantly longer compression period per cycle (10.9 s vs 6.3 s), expelled significantly more venous blood (121+/-68 vs 81+/-63 mL P<0.001). Refill time of the rapid inflation device was shorter in comparison with the sequential compression device (15+/-2.2 vs 25+/-4 s P<0.001), suggesting incomplete vein evacuation. The initial IPC devices were pumps with a single-chamber pressure cuff that applied a uniform level of compression to the entirety of the limb. Total and peak volume of blood expelled per hour during compression were calculated using flow data and the individual cycling rate.īoth devices increased venous flow velocity, up to 3.8 times the baseline (all P<0.001). Pneumatic compression devices have been utilized in the medical management of swelling since the early 1950’s (8,9). Refilling time was determined from velocity recordings of the common femoral vein. ![]() Baseline and augmented flow velocity and volume flow were measured at the level of the common femoral vein, above the saphenofemoral junction. Mortality (0.43) was applied only in intensive care and long-term. The two devices were tested in 12 normal volunteers in the semirecumbent position using duplex ultrasound. Objectives: Traditional intermittent pneumatic compression device (IPCD) has. The former, by sensing venous refill time, commences compression when the calf veins are refilled. The aim of our study was to compare the hemodynamic effectiveness of the portable sequential compression device (SCD Express Compression System, Tyco Healthcare Group LP, Mansfield, MA, USA) with a rapid inflation device (VenaFlow, Aircast, Inc, Summit, NJ, USA). ![]() Sequential leg compression has been previously shown to be superior to uniform compression. ![]()
