Hemodynamic changes in prone position - a non‑invasive physiological study

Abstract

No differences in cardiac output and preload were detected after proning in unsedated healthy volunteers. Prone position was associated with changes of systemic vascular resistance, blood stagnation in jugular catchment area and, in unsupported prone position, increased collapsibility of inferior vena cava.
