Abstrákta:The aim of this study was to determine whether weight force application to the lower torso can lead to impairment of inferior vena cava (IVC) and cardiovascular parameters. Using ultrasound sonography and impedance cardiography, the effects of a weight force application of 5, 10, 15, and 25 kg to the lower torso, placed in prone position, on IVC diameter and maximal blood flow, mean artery pressure, stroke volume, heart rate, cardiac index, cardiac output, oxygen saturation (Spo2), and acceleration index were investigated in 6 healthy volunteers. The following parameters showed a statistically significant correlation with the amount of weight force applied: IVC diameter: r =-0.83, P < .001; IVC maximal blood flow: r =-0.76, P < .001; cardiac index: r =-0.33, P < .05; and cardiac output: r =-0.32, P < .05. Application of moderate weight force to the lower torso can lead to major changes in IVC parameters and minor changes in cardiovascular parameters.   The aim of this study was to determine whether weight force application to the lower torso can lead to impairment of inferior vena cava (IVC) and cardiovascular parameters.
