Conditions

Severe pneumonia in African children Infections and Infestations

Interventions

The trial has two strata: Stratum 1: severe hypoxia, SaO2 <80%)
and Stratum 2: hypoxia SaO2 =80% and <92%). Children in Stratum 1 (2-arm, 1:1 ratio) will all receive oxygen and randomisation will allocate participants to one of two methods of oxygen delivery: 1.
