Measurement of oxygen saturation is considered the ‘fifth vital sign’ but is challenging to measure in infants and preschool children in community settings.
Several national and international guidelines advocate oxygen saturation measurement in primary care for children presenting with acute respiratory illness to aid decision making on referrals to secondary care, but some think the technology has led to overdiagnosis, such as increased admission rates for infants with bronchiolitis.1
Oxygen saturation monitoring for children is not widely available in general practices2 despite acute respiratory infections (ARIs) accounting for a high number of presentations in primary care.3
Easier and more reliable ways to measure oxygen saturation in children could not only aid clinical decision making in primary care but could also provide a useful tool for care delivered at home (especially in any future respiratory pandemic). The unmet need is also relevant to resource-limited settings, where pneumonia remains the largest cause of mortality in those aged under 5 years.4
We ran a multidisciplinary, ideation workshop (with parents, paediatric nurses, GPs, paediatricians, and engineers; n = 14) to identify problems associated with measuring oxygen saturations in infants and young children, and to discuss possible solutions (themes are summarised in Table 1).

|Problems||What we could do now||Ideas to take forward|
Challenges to the measurement of oxygen saturations in young children in the community have long been a neglected problem. Improving how we do this has the potential to reduce deaths from pneumonia in resource-limited settings,4 and improve trust in the interface between families, primary, and secondary care while cutting healthcare costs.3
