Femoral vein-to-artery diameter ratio to predict fluid responsiveness
This project will test whether a bedside ultrasound measurement of the femoral vein-to-artery diameter ratio can tell if mechanically ventilated ICU patients with acute circulatory failure or shock will increase their cardiac output after a 500 mL fluid bolus.
-
Fluid balance guided by mVExUS in ICU patients on CRRT with acute kidney injury
This trial tests whether using modified venous excess ultrasound (mVExUS) to guide fluid removal in ICU patients on CRRT with AKI can achieve a better fluid balance in the first 72 hours compared with standard care.
-
Skin blood flow and capillary refill monitoring in ICU patients with circulatory failure
This study will see if capillary refill time and local skin blood flow change after routine treatments (fluids, vasopressors, or inotropes) in ICU patients with acute circulatory failure from sepsis or heart failure.
