Automatic versus manual oxygen titration using a novel nasal high-flow device in medical inpatients with an acute illness: a randomised controlled trial

摘要

Guideline recommendations state oxygen should be administered to acutely unwell patients to achieve a target oxygen saturation (SpO2) range. The current practice of manual oxygen titration frequently results in SpO2 outside of a prescribed range. The aim of this study was to assess the efficacy of automatic oxygen titration using a closed-loop feedback system to achieve SpO2 within a prescribed target range
