WebDETERMINING FLUID RESPONSIVENESS. To determine fluid responsiveness, a dynamic assessment is performed, which challenges the heart with a small amount of fluid to gauge its response. Two ways of performing this fluid challenge are a fluid bolus or a passive leg raise (PLR). The PLR translocates 250-300 cc of blood from lower extremities into ...
