Added value of pulse oximetry to 2014 WHO IMCI guidelines for identifying deaths

IMCI=Integrated Management of Childhood Illnesses. SpO₂=peripheral arterial oxyhaemoglobin saturation. *Overall interpretation of less than 90% scenario: a total of 24 deaths occurred by 2 weeks, 18 of which were missed by clinical signs. Applying a less than 90% SpO₂ threshold identified four (22·2%) more deaths than clinical signs alone. A total of ten deaths were identified assuming pulse oximetry was available and a less than 90% SpO₂ threshold was applied.
