Which breathing aid works best for babies after heart surgery?

This study looks at 200 infants under 1 year old who had heart surgery for congenital heart disease. After surgery, when the breathing tube is removed, babies need extra help breathing. This study compares two standard methods—high flow nasal cannula and non-invasive positive pressure ventilation—to see which one leads to fewer breathing failures and better outcomes. The goal is to find the safest and most effective way to support these babies' breathing after surgery.
