Accurate assessment of preload status is a major concern in the resuscitation of the critically injured patient. Of the three physiologic determinants of stroke volume, preload is the variable that is most frequently influenced by an insult or intervention or both in the trauma. patient. in the critically injured patient, clinicians focus on the preload status to restore and maintain intravascular volume in attempts to optimise cardiac output and: oxygen delivery. Until recently, efforts to measure and optimize ventricular preload have focused on intracardiac filling pressures (central venous pressure and pulmonary artery occlusion pressure), The purpose of this review is to discuss the application of volumetric measurements that provide a more accurate means of delermining recruitable ventricular preload in the critically injured patient.
