TEE (transgastric LV short-axis view) showing normovolemia versus hypovolemia
TEE (transgastric LV short-axis view) showing normovolemia versus hypovolemia
Intraoperative TEE TG LV short-axis images in a patient at baseline (left panel) and after acute blood loss of approximately 10 mL/kg (right panel). Hypovolemia caused by acute blood loss decreased TEE LV short-axis cross-sectional area and diameter at both end-diastole and end-systole. Each 1.75 mL/kg blood loss will acutely decrease LV end-diastolic area by 0.8 cm2 and LV end-diastolic diameter by 0.1 cm[1].
TEE: transesophageal echocardiography; TG: transgastric; LV: left ventricular; SAX: short-axis.
