TPTD requires indicator injection via a central venous catheter (usually placed via the jugular or subclavian vein). However, superior vena cava access is often not feasible due to the clinical situation. This study investigates the conformity of TPTD using femoral access.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Methods<\/jats:title>\n                        <jats:p>This prospective study involved an 18-month trial at a medical intensive care unit at a university hospital.

GEDVIfem and GEDVIjug were significantly correlated (r<jats:sub>m<\/jats:sub> = 0.88; <jats:italic>P<\/jats:italic> &lt; 0.001), but significantly different (1,034 \u00b1 275 vs. 793 \u00b1 180 mL\/m<jats:sup>2<\/jats:sup>; <jats:italic>P<\/jats:italic> &lt; 0.001).
