We designed this study to expand the usage of ultrasound to detect early occurrence of hypovolemia. We explore the potential use of inferior vena cava (IVC) and abdominal aorta (AA) diameter index (IVC:AA) measured ultrasonographically to detect class 1 hypovolemic shock with blood loss less than 15%.ᅟ
