| Summary: Six different pneumatic compression devices (VenaFlow calf, Jobst calf, Jobst thigh, Kendall thigh, Venodyne calf, and PlexiPulse foot) were compared for their effect on venous blood flow and the results were compared to that of active and passive dorsiflexion. Doppler measures were taken proximal to the greater saphenous vein-femoral vein junction. The Aircast VenaFlow produced venous velocity rates most similar to those of active or passive dorsiflexion. The venous velocity achieved with the other devices was significantly lower than active or passive dorsiflexion and the Aircast VenaFlow. "The relative effectiveness of pneumatic compression devices, particularly with respect to increasing venous blood flow in the lower extremity, may correlate well with how closely the device simulated the physiologic contraction of the calf muscles." |
