Dear Editor,

Severe hypoxia is detrimental during critical illness, but hyperoxia has also been associated with adverse outcomes [1, 2, 3]. Harm from hyperoxia may be a biological consequence of oxidative damage or reflect iatrogenic injury resulting from more aggressive care. ARDSnet protocols include conservative oxygenation targets (arterial oxygen saturation (SpO2) 88–95%) [4] in recognition of the fact that the harms of high inspired oxygen fractions (FiO2) and ventilation volumes and pressures may outweigh any advantage of an additional buffer against hypoxia.

Where does this balance of harm and benefit of oxygenation lie on the paediatric intensive care unit (PICU)? As part of preliminary work towards our Oxy-PICU trial for conservative versus liberal oxygenation targets, we investigated current practice at a large general PICU over 12 months. Children were selected on the basis of a measured actual oxygen content in arterial blood (PaO2):FiO2ratio (PF) of <300 mmHg (8217...
