![]() ![]() You may need this device if your legs are swollen. To use the device, you lie still while the cuff inflates around your leg at a programmed rate. 1 These pneumatic stockings increase lower limb venous return, causing acute but transient decrease in pulmonary artery blood temperature. The device squeezes your blood vessels together to force old blood out of your legs and let in fresh blood. cardiac output, sequential compression device, leg LOWER limb pneumatic compression devices are recommended to prevent venous thromboembolism in many intensive care unit patients. We postulate that sepsis and the ensuing volume resuscitation may have resulted in cool extremities and that the patient’s low flow state amplified the impact of cool fluid being delivered to the central circulation. Sequential compression device is an inflatable cuff that you wear around your leg or foot. Not so long ago, SCDs were used to prevent Deep Vein Thrombosis (DVT). What are SCDs SCDs (sequential compression devices) are simply therapeutic massage devices. In this blog, you'll learn what SCDs are, what they are used for, who should use it and the current solutions available. Neither one-leg SCD nor calf SCD compression produced enough volume to create a CO waveform by itself. All thanks to sequential compression devices (SCDs). When a patient is immobile for long periods of time, as in recuperation from an injury, blood tends to pool in the calf area of the lower leg. ![]() In this extreme example, because the patient was febrile and edematous with a low stroke volume, the volume of cool blood from the two legs squeezed by the long-sleeve SCD was enough to create a CO waveform and CO calculation by the computer. Sequential Compression Devices, or SCD’s, (also known as Lymphedema pumps) are designed to limit the development of Deep Vein Thrombosis (DVT) and Peripheral Edema in immobile patients. Given that the thermistor on the PAC measures temperature changes, we hypothesize that the inflation cycle of the compression stockings brought cool blood from the legs into the central circulation, resulting in a decrease in pulmonary artery blood temperature. In the current patient, the measure of CO was significantly impacted by the use of SCDs. When using a PAC, CO is inversely proportional to the area under the thermodilution curve and is determined by injectate volume, blood temperature, density factor, and computation constant. ![]()
