This is an observational study that will examine the possibility of determining the type of Acute Kidney Injury (AKI) using bedside ultrasound machines.
The investigators hypothesize that different types of AKI (pre-renal, renal, and post-renal) are associated with different inferior vena cava diameters and collapsibility index. The investigators will include subjects ages 18-89 years with AKI (creatinine of 2mg/100ml or higher for less than 24 hours from baseline creatinine ≤1.2 or with unknown baseline creatinine). Standard of care treatment will not be different for patients taking part in this study. Participants will have bedside ultrasounds on days 0, 1, and 3, and baseline and follow-up data will be collected from medical records.

Maximum and Minimum Diameters of the Inferior Vena Cava in Patients With Acute Kidney Injury
The investigators will measure the maximum and minimum diameters of the inferior vena cava with patients with acute kidney injury.
Time frame: Day 1 of ICU admission
Percent Collapse of the Inferior Vena Cava in Patients With Acute Kidney Injury
The investigators will measure the maximum and minimum diameters of the inferior vena cava with patients with acute kidney injury and calculate the percent change between the maximum and minimum diameters.
Time frame: Day 1 of ICU admission
