Dilated ivc with 50% collapse with sniff
WebThe IVC was identified in longitudinal access. The IVC was flat with over 50% collapse with respirophasic measurements. There was evidence of volume depletion and fluid tolerance. A bedside IVC ultrasound was performed to assess volume status in setting of fluid overload. The IVC was identified in longitudinal access.
