Overview
The goal of this clinical trial is to learn an Intermittent Pneumatic Compression Device (IPCD), VenAir, effectiveness in healthy adults. The main questions this research aims to answer are: 1. The hemodynamic performance of VenAir paired with the thigh garments, calf garments, and foot garments is not inferior to that of SCD700 paired with the corresponding garments. 2. The hemodynamic performance of VenAir paired with the thigh garments, calf garments, and foot garments is not inferior to that of SCD700 paired with the thigh garment. Researchers will compare VenAir and the SCD700 to see if the hemodynamic performance of VenAir is as well as or not worse than the SCD700. Participants will lie down and rest for approximately 30 minutes to stabilize their heart rate. The researcher will then use ultrasound to measure the participant's blood flow while they wear different leg garments (one at a time) and also when no garment is worn.
Interventions
- Device VenAir
VenAir is an intermittent pneumatic compression (IPC) device intended to help prevent venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). In this study, VenAir is applied to the participant's lower limb under standard operating settings, and hemodynamic performance is measured for comparison with SCD700. - Device SCD700
SCD700 is a commercially available intermittent pneumatic compression (IPC) device used to prevent venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). In this study, SCD700 is applied to the participant's lower limb under standard operating settings, and hemodynamic performance is measured to compare with VenAir.
Primary outcome measures
- Peak Velocity of Blood Flow Increasement [Time frame: During and immediately after device application]
