Diagnostic Highlights

General Comments: No one specific diagnostic test identifies the degree of hypovolemic shock state. Several laboratory indicators do provide valuable information on the status of the patient, however. These include ABGs, hemodynamic parameters (cardiac output and cardiac index, oxygen delivery, oxygen consumption, central venous pressure, pulmonary capillary wedge pressure, and systemic vascular resistance), blood lactate level, hemoglobin, and hematocrit. Radiographic and imaging studies are important depending on the location of interest and might include: chest and abdominal x-rays, transesophageal echocardiography, aortography, computed tomography, magnetic resonance imaging, or focused abdominal sonography for trauma (FAST).
