NCT ID NCT05754034
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 8 times
Summary
This study compares high flow oxygen to standard oxygen for adults with dangerously low blood oxygen (acute hypoxemia) in five East African hospitals. Researchers want to see if high flow oxygen lowers death rates and uses oxygen more efficiently. About 1,600 participants will be randomly assigned to one of the two oxygen methods.
