According to the class of hypovolaemic shock, a blood loss less than 750 ml is not associated with the physiological changes. As a result it may cause a delay in fluid resuscitation. We postulate inferior vena cava (IVC) diameter reduction in inspiration and expiration may resemble the significant volume of blood loss in a healthy adult. We conducted a study to examine the changes of the IVC di...
