Comparing how VenAir and SCD700 compression garments affect leg blood flow
Evaluating the Hemodynamic Performance of the VenAir Sequential Compression System
This test will see if the VenAir intermittent pneumatic compression device produces similar blood flow effects as the SCD700 in healthy adults aged 20–64.

What this trial studies
Healthy adults aged 20–64 will lie down and rest to stabilize heart rate, then wear thigh, calf, and foot garments from both the VenAir device and the SCD700 in separate measurements. Researchers will use ultrasound to measure venous blood flow with each garment configuration and with no garment as a baseline. The main goal is to determine whether VenAir's hemodynamic performance is not inferior to the SCD700 for each garment type. Measurements are done sequentially during a single visit at the study site.
Who should consider this trial
Good fit: Healthy adults aged 20–64 whose leg circumference fits the device garments and who have no cardiovascular disease, diabetes, recent thrombotic events, significant leg wounds or pregnancy are ideal candidates.
Not a fit: People with cardiovascular disease, prior or suspected deep vein thrombosis or pulmonary embolism, significant leg wounds or edema, pregnancy, or those outside the 20–64 age range are unlikely to receive benefit from participating.
Why it matters
Potential benefit: If VenAir matches the SCD700, it could provide an additional device option that preserves the expected blood flow benefits of intermittent pneumatic compression.
How similar studies have performed: Sequential intermittent pneumatic compression devices such as the SCD700 have been shown in other studies to increase venous blood flow and reduce VTE risk, so this study compares a new device to that established benchmark.
