NCT ID NCT04934566
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 48 adults on ECMO for severe heart shock to see if oxygen levels measured from different spots in the body agree. Doctors checked blood from the ECMO machine, a neck vein, and a lung artery. The goal was to improve monitoring without adding risk.
