The objective of this study is to ascertain the diagnostic threshold of end-tidal carbon monoxide (ETCOc, adjusted for ambient CO levels) within the first three days postpartum, stratified by neonatal age at birth. Additionally, the study aims to evaluate the concordance of the risk range of ETCOc, as measured by non-dispersive infrared spectroscopy, with existing literature, and to assess the reliability of this technology in the management of neonatal hyperbilirubinemia.

| The ETCOc values of newborns were measured, and the optimal ETCOc threshold values between different time points of the TSB group were obtained. | Establish an ETCOc diagnostic threshold for assessing the risk of hyperbilirubinemia in the early postnatal period based on the infant's age at birth. Determine the reliability and repeatability of ETCOc detection using non-dispersive infrared spectroscopy technology.Compare the concentrations of ETCOc between different groups and employ the ROC curve method to ascertain the optimal cut-off values of ETCOc at various time points across the TSB groups. | The non-dispersive infrared spectroscopy technique was used to detect ETCOc in newborns at 12 hours, 24 hours, 48 hours and 72 hours after birth (the ETCOc detection should be completed within 4 hours at each time point) |
| The ETCOc values of newborns | The ETCOc values of newborns were measured, and the optimal ETCOc threshold values between different time points of the TSB group were obtained. | 12 hours, 24 hours, 48 hours and 72 hours after the birth of the newborn |
