Commentary on Twitter

COAST RCT O2 in African children >28 days w severe pneumonia, less is more!
SO2 80-91%? no O2 ➡️48h mortality comparable to low-flow O2/HFNC. O2-sparing strategies potentially offer cost-effective approaches to reduce requirements in low resource settings. https://t.co/8JHit94WQY pic.twitter.com/EEIybSOlmy
