Aim It takes several minutes for infants to become pink after birth. Preductal oxygen saturation (SpO 2 ) measurements are used to guide the delivery of supplemental oxygen to newly born infants, but pulse oximetry is not available in many parts of the world. We explored whether the pinkness of an infant's tongue provided a useful indication that supplemental oxygen was required. Methods This was a prospective observational study of infants delivered by Caesarean section. Simultaneous recording of SpO 2 and visual assessment of whether the tongue was pink or not was made at 1–7 and 10 min after birth. Results The 38 midwives and seven paediatric trainees carried out 271 paired assessments on 68 infants with a mean ( SD ) birthweight of 3214 (545) grams and gestational age of 38 (2) weeks. When the infant did not have a pink tongue, this predicted SpO 2 of <70% with a sensitivity of 26% and a specificity of 96%. Conclusion Tongue colour was a specific but insensitive sign that indicated when SpO 2 was <70%. When the tongue is pink, it is likely that an infant has an SpO 2 of more than 70% and does not require supplemental oxygen.
