To define reference ranges for the 3% and 4% mean desaturation nadir in healthy children under 12 years: observational study using oximetry motion-resistant technology

In 2020 we published data defining reference ranges for pulse oximetry parameters generated from oximeters which use short averaging times and contain motion rejecting algorithms in healthy children under 12 years of age.1 This paper reported the minimum saturation (SAT min), which is the lowest oxygen saturation recorded, a value that is commonly reported in the paediatric literature.1 2 This is limited by the fact that it takes into account the single most severe dip, without reflecting the pattern of desaturations occurring throughout the period of sleep. It is increasingly recognised that the SATmin may not provide a representative reflection of the impact of sleep disordered breathing (SDB) on oxygen saturations. Recently there has been interest in reporting the mean desaturation nadir (MDN).3 This is an average of the minimum saturation resulting from desaturations from baseline and may be a more...
