Comparison of Different Intermittent Pneumatic Compression Devices for Deep Vein Thrombosis

Various kinds of intermittent pneumatic compression devices (IPC) with particular ways of compression have been developed and used for prevention of deep vein thrombosis. There are still some controversies about the physiologic properties and clinical impact of numerous issues including the variety of the cuff length, inflation rate, compression sequence, compression-relaxation cycle rate, and pressure generation characteristics. This study is designed to compare clinical efficacies as well as venous hemodynamic improvements between Simultaneous bilateral compression with fixed venous refill time versus alternate compression with adjusted refill time
