Overview

The goal of this observational study is to gather more information on kidney oxygen levels in babies with a patent ductus arteriosus (PDA), and evaluate the relationships between kidney oxygen levels, PDA status and kidney injury.

Researchers will do this by looking at ultrasound images of the heart, analyzing substances in the urine, and evaluating oxygen levels in the kidneys.
