Point-of-care ultrasonography (
#POCUS) is a noninvasive bedside imaging modality used to assess intravascular volume status in hospitalized or emergency department patients with possible
#VolumeOverload.
POCUS evaluates the inferior vena cava, internal jugular vein, and lung parenchyma with high-frequency linear, low-frequency phased-array, and low-frequency curvilinear probes.
