Which breathing aid works best for pneumonia? new study aims to find out

This study compares two ways to help pneumonia patients who have trouble breathing: alternating between a mask that helps push air in (non-invasive ventilation) and high-flow oxygen through the nose, versus using high-flow oxygen alone. The goal is to see which approach improves oxygen levels and patient comfort better. About 128 adults with pneumonia and low blood oxygen will take part.
