Hypovolemia Assessment

Echocardiographic signs of a suspected diagnosis of hypovolemia are an underfilled right ventricle, hyperkinetic left ventricular wall motion, and close ventricular walls, or kissing trabecular muscles. Hypovolemia can be detected by measuring left ventricular end-diastolic volume or area (54) and is therefore a clinical variable used to assess preload.

Closure of left ventricle in systole

i. >50% within normal limits

ii. <30% significantly depressed

iii. 90-100% hyperdynamic
