Solar-powered O2delivery for the treatment of children with hypoxaemia in Uganda: a stepped-wedge, cluster randomised controlled trial

Supplemental O2is not always available at health facilities in low-income and middle-income countries (LMICs). Solar-powered O2delivery can overcome gaps in O2access, generating O2independent of grid electricity. We hypothesized that installation of solar-powered O2systems on the paediatrics ward of rural Ugandan hospitals would lead to a reduction in mortality among hypoxaemic children.
