Decision-making procedure directed by focused cardiopulmonary ultrasonography.

Ultrasonography Finding Question	Answer Choices
What is the IVC diameter?	<10 mm/≥20 mm*/other
What is the RV size?	Normal or dilated*
Is there evidence of diffuse interstitial syndrome?	Yes* or no
What is the LV systolic function?	Hyperdynamic/normal/moderately impaired*# /severely impaired*#

*If none of these choices applied, fluid resuscitation was given at 30 mL/kg within 3 hours; if any of these choices applied, fluid resuscitation was cautiously performed; if two of these choices applied, fluid resuscitation was dispensed and vasopressor support was enhanced. ^#Inotropic support was initiated as needed.

IVC, inferior vena cava; RV, right ventricular; LV, left ventricular.
