The Physiology of Passive Leg Raising

The one finding in your paper that really emerged as probably the best was the passive leg raising. So could you describe how that's done and how you use the measurements that you get from that maneuver to gauge the need for resuscitation? Yeah so the Passive Leg Raising what you basically do is you tip the patient and then you raise the patient's legs. The physiology behind it is that there's a lot of blood that's pooled in the patient’s legs and when you actually tip the patient over the fluid should go back into the circulation without giving a fluid bolus.
