Trial Outcomes & Findings for Vasculaire Compression System Increases Flow Velocity in the Femoral Vein (NCT NCT01240330)

NCT ID: NCT01240330

Last Updated: 2011-03-03

Results Overview

The femoral vein in the mid-thigh area was located and the femoral venous Peak Flow Velocity (PFV)was measured using duplex ultrasound during the compression phase of treatment. PFV is the maximum velocity of blood flow achieved when the foot and calf compression is applied. The PFV was then compared to the subject's own baseline PFV using a paired t-test.

Measure
Pneumatic Compression Therapy
The Vasculaire System provided compression therapy to the foot and calf of the participant's right leg. The system compressed and released the foot and calf to increase blood flow and circulation of the participant's right limb. Ten cycles of compression therapy was applied. Increase in blood flow rate was measured in the participants femoral vein using duplex ultrasonography.

Change in Femoral Venous Peak Flow Velocity Compared to Resting Baseline
18.9 cm/s
Interval 16.3 to 21.6

SECONDARY outcome

Timeframe: 3 measurements/10 minute therapy

Peak Flow Velocity (PFV) from the compression phase subtracted from the PFV from the decompression phase divided by the PFV from the decompression phase expressed as the percent augmentation.
