Oxygen saturation nomogram by pulse oximetry in the first 24 h of life (original) (raw)

Journal of Clinical Neonatology, 2021

Abstract

Aims: The aim of this study is to plot a nomogram of oxygen saturation (SpO2) in healthy newborns during the first 24 h of life and study the possible relationship to birth weight, mode of delivery, parity, and gender. Materials and Methods: This was a retrospective study done on a healthy newborn population. The primary purpose of the study was to see preductal saturation during the first 24 h of life and to plot a nomogram of the 5th and 95th percentile for the first 24 h of life. Results: From 5252 babies born in our hospital during 2016, 4139 (78.8%) were included in the study. Mean SpO2 was 98.82%, with a standard deviation of 1.21%. Saturation nomogram of 5th and 95th percentile of preductal saturation during the first 24 h of life was between 96% and 100%. There was no significant difference in gender and mode of delivery. Conclusion: Baseline arterial SpO2 was relatively stable during the first 24 h of life. Moreover, it was similar to the other studies reported earlier.
