Ultrasound vs. blood test: which better measures lung severity?
NCT ID NCT05631756
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 86 ICU patients with a lung condition called interstitial syndrome. Researchers compared a lung ultrasound score with a standard blood oxygen test to see if the ultrasound could reliably measure how severe the condition was. They repeated both tests at the start, 24 hours, and 48 hours to track changes. The goal was to see if the simpler, radiation-free ultrasound could be a valid tool for monitoring these patients.
