Passive leg raising maneuver for fluid responsiveness
Passive leg raising maneuver for fluid responsiveness
Passive leg raising maneuver. After starting with the head elevated to 45 degrees, rapidly repositioning the patient with legs elevated to 30 to 45 degrees allows autotransfusion of blood from the legs into the thorax. An increase in cardiac output suggests that the patient might be fluid responsive.
