Simple pulse test could spot hidden heart defects in newborns
NCT ID NCT03078218
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using a pulse oximeter (a small sensor on the foot or hand) to measure oxygen levels in all seemingly healthy newborns can help find hidden, life-threatening heart defects early. Over 44,000 babies took part. The goal was to see if this screening reduces serious complications and death, and if it is worth the cost for the French healthcare system.
