Analisis Pengaruh Ketinggian Infus dan Posisi Tubuh terhadap Kelancaran Aliran Infus dan Tekanan Vena

Intravenous fluid therapy is a nursing procedure requiring precise regulation of pressure and flow rate to maintain patient hemodynamic stability. The height of the IV fluid container and body position are physical factors that can influence hydrostatic pressure, venous pressure, and the smoothness of the infusion flow. This study aimed to analyse the effects of infusion height and body position on infusion flow and venous. The method employed is a literature review with a descriptive approach. A quantitative analysis method was employed, observing variations in infusion height and body position. Observed parameters included blood pressure, infusion flow rate, venous pressure, and flow continuity. Control variables included the type and size of the IV tubing, fluid type, catheter size, fluid volume, and the condition of the infusion system. Analysis results indicated that differences in infusion height affect hydrostatic pressure and fluid flow rate. The greater the height difference between the IV fluid and the insertion site, the higher the generated pressure, leading to an increase in fluid flow. Changes in body position such as supine and semi-Fowler positions can also influence central venous pressure and hemodynamic status. Thus, proper adjustment of infusion height and body position is essential to ensure smooth fluid therapy and maintain patient hemodynamic stability.
