Determining reference data for overnight oximetry in neonates: A pilot study

To determine the variability of overnight oximetry parameters in a group of normal, healthy term infants; to enable the calculation of the number of subjects required to produce reliable reference ranges for neonatal overnight oximetry. A convenience sample of normal, healthy term neonates was recruited. Each had overnight oximetry using the Masimo SET Radical oximeter (data downloaded using Profox software). The report included the number of oxygen desaturation events (an absolute decrease in SpO2 of 4 or more), and the duration of oxygen saturations
