Excerpt
Predicting fluid responsiveness is a topic of major interest. The passive leg raising (PLR) manoeuvre has been recently proposed and tested [
1‐
8]. PLR is based on the principle that it can induce an abrupt increase in venous return secondary to auto-transfusion of peripheral blood from capacitive veins of the lower part of the body [
9]. The attractiveness of PLR relates to the apparent simplicity of its physiology, but it presents some limitations [
5,
6]. In particular, the increase in preload is not predictable and may be insufficient to challenge the right cardiac function curve [

SUPINE) or semi-recumbent (PLR
SEMIREC)––remains a matter of debate [
